MS Exchange Server 2007 - Security &
Mar 30, 2009
I am trying to setup the trial of Exchange 2007, everything is installed. However, I am unable to connect to the SMTP server
Quote:
452 4.3.1 Insufficient system resources
Connection to host lost.
After googling around, I found the solution, I changed the settings xml file and now I have to restart the service but I can't seem to find the "Restart Service" option in the EXCHANGE MANAGEMENT CONSOLE?
Also, how secure is exchange by default - any guides/tips so I can secure this test environment?
Any 3rd party Anti-virus/worm/spam solutions for Exchange that are affordable instead of MS Forefront?

does anyone have a fix for the Exchange 2007 kerberos issue when connecting Kayako to Exchange via pop3 or imap?
kayako says:
Quote:
The reason for the error you are getting is a bug in MS Exchange 2007. The exact reason is, Exchange server falsely advertises that it support Kerberos authentication even when it is configured not to use Kerberos. This causes the fetch request to fail from PHP as PHP-imap always tries to use Kerberos first.
The workaround to this issue is either to use a different mail server or compile PHP without Kerberos support(in that case it will simply ignore Exchange's erroneous behavior regarding Kerberos).
If possible you may setup a secondary mail server (Non exchange 2007) and forward the required emails there and configure help desk to fetch the emails from the secondary email server(non-exchange 2007) instead of your Exchange server 2007.

ive set up Exchange 2007 on WS2008. I have a domain "fasterfasterfaster.net"
its nameservers are changed correctly and is pointing to the right IP address including the @ and CNAME records.
the mx record is set to mail.fasterfasterfaster.net
my DC is called "faster.local"
in the org configuration > hub transport, I have accepted domains:
fasterfasterfaster.net Authoritative
mail.fasterfasterfaster.net Authoritative
faster.local Authoritative
also in the org config, there is an internet send connector. its FQDN is mail.fasterfasterfaster.net.
for the Server config > hub transport:
Client is enabled with the FQDN: mail.fasterfasterfaster.net and permission groups enabled:
Anonymous, exchange users, exchange servers and legacy exchange servers
the Default is enabled with its FQDN to machineName.faster.local and same permission groups as above.
problem is, I am unable to recieve any emails (no bouncebacks)
And when I send email from an exchange account, the recipient recieves it from account@faster.local

I'm sure by now most of you have read the Web Server Optimization Guide by Shaw Networks. It came in handy for me when I was first starting out, I reduced my load & memory usage by tonnes. I thought I would make a new thread with an updated How-To.
Recommended Tools/Programs:
Putty - Free SSH Client - [url]
WinSCP - Free SFTP and SCP Client - [url]
MySQL Optimization:
BACKUP:
cp /etc/my.cnf /etc/my.cnf.backup
Use Pico (pico /etc/my.cnf) or Download via WinSCP for editing,
Delete everything that is currently in the file and add the following...
Code:
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock

I've recently had a number of enquiries from hosted clients and potential customers requesting SharePoint hosting for use in connection with their current packages. I've used Windows SharePoint Services 2.0 in the past, but am specifically looking into the latest and greatest release of SharePoint to date to install - SharePoint Server 2007.
I've read over Microsoft's server requirements for running SharePoint, who recommend a 3GHz or higher processor and 2GB RAM for web servers, and 4GB RAM for SQL servers. To me, this seems ridiculous for the small number of clients I'll ever be hosting, and who will only have a small number of SharePoint users per site.
Those with any experience of SharePoint hosting please share your opinions of SharePoint hosting on various server configurations, as I'm interested to know how it performs. As I'll only have a small user base, would running SharePoint fully on one existing IIS 6 web server do the trick? What processor should this machine have, and amount of RAM to run SharePoint well?

Just today we started having some problems with our exchange server...everything was working fine until around 10:00 A.M this morning.
We've started getting sporadic reject messages from people that we have always been able to email in the past.
These are a few of the NDR's we've received.
There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator.
<mail.uaminc.com #5.5.0 smtp;550 not local host baronintl.com, not a gateway>
The following recipient(s) could not be reached:

<mail.uaminc.com #5.5.0 smtp;530 authentication required for relay (#5.7.1)>
Theres more as well, but that pretty much sums up the main issues really....as I said, these were working fine for the last year, until today. No changes have been made on our exchange server.
We have GFI Mail essentials installed with SPF records turned on.
We have reverse dns setup through Time Warner Telecom for our IP.
I can send email to my hotmail address, but yahoo rejects it.
I've checked dnsstuff.com and dnsreport.com and we're not on any blacklists.
I'm not exactly sure where else to look.
These mail servers rejecting our email are not from just 1 ISP or 1 mail server, these are from companies in different states/countries.

can someone here help me setup/configure exchange server? I really have no idea but interested in doing so on my dedicated server.
I just want to know how to say, setup email accounts/web access.
Right now, just installed WS2003 EE R2 with updates and installing other things too like SQL Server 2005/AV/ISA Server
I take it I need to make the machine into a domain?
I have 2 IP Addresses assigned to me. and I have 2 domains, so I'm thinking about configuring each domain for an IP Address.
I would ideally like to have email addresses for both domains but going to test it on 1 domain first before proceeding onwards.
It would be appreciated if someone could just jot down on how to go about setting up Exchange, how to configure it...and pretty much it. I will be using Exchange 2003 Enterprise

My entire hosting life, I've been with Linux, so now that I'm looking to setup a Blackberry Enterprise Server account, things are very new to me.
Let me explain. I have a Blackberry and would like to setup a BES system such that I can get push email, calendar, and contacts for OTA syncing from my own personal.com
So, the question is, what sort of hosting package do I need to do this? And, will this cost a lot of money?
Again, I'm completely new to Windows hosting, so I'm not sure what I need and if it's even possible.

We are currently using Veritas BackupExec to backup our in-house Exchange Server. However, we ALWAYS get some type of error when using this program, whether its the "Advanced Open File" piece of the program, or just what it calls a "corrupt email," I'm fed up with it. Does anyone have any suggestions for a sub-$100 program that can backup everything Exchange (database, emails, etc.) and has open file protection (for backing up system files, etc.)?

I have two questions that hopefully someone will be able to help me out with. The first, is my partner and I want to provide server redundancy for our clients. Our set-up is as follows: two identical servers with multiple virtual machines (about 4) on each. One for SQL, one for IIS, etc. We also have a ServerIron XL to connect the two together and provide replication and load balancing. So the question is, has anyone here used a ServerIron XL and how easy is it to use/how effective is it? The second question is, we would like to provide our clients with hosted Exchange. I have set up and maintained a few Exchange 2007 servers, but only for a single company with a single domain. What would be the best way to go about providing a hosted Exchange solution?

webhost that supports Microsoft exchange server
I have a client who needs a solid webhost that supports MS exchange server for his email.
I usually recommend Bluehost , but I guess they donât do this. Quick turnaround time on email tech issues (2-4 hours) and phone support is also needed. The client is definitely a phone person.
It should be Wordpress friendly. My CMS that I'm using is actually Textpattern, but most people don't know it so I just opt for the default popular version, Wordpress.
At the minimum, it should support; PHP 4.3+
MySQL 3.23+

if I have a dedicated server with WS2003, would I be allowed to install my own software (with license)? such as MS SQL Server - I have an MSDN subscription and multiple licenses.... would this be ok to do so?
What about Exchange Server? I have a License for that also...again, MSDN subscription

I'm currently with Steadfast Networks for my VPS (Linux). We are now in need of shared MS Exchange Hosting plan. Although I found some companies offering Exchange Hosting, they do not offer VPS's. Does anyone knows of any reliable company offering both?
I want someone (well maybe except Rackspace) who is reliable, has good feedback and provides good uptime and customer service.

We've been buying our Microsoft licences retail which was fine when we were a lot smaller. But as we grow I was thinking about the joining the Microsoft services provider licence agreement.
Can anyone out there give me an idea if this is a worthwhile route to take for a managed services webhost? If so what are the requirements, we aren't a Microsoft partner, have no Microsoft certifications, etc.
What are the initial costs? What are the long term costs?

On of our clients use an MS Exchange 2003 SBS server, with exchange for their internal email. We provide them with a domain, ADSL (which uses dynamic DNS) and POP3 email. They don't have an spam filter program on the exchange server itself due to costs, so I have setup each user on the Exim server, which runs ASSPX for anti-virus / spam filter / etc.
Then I setup the SBS 2003 server to pull the email via POP3, but this doesn't seem to work too well, cause the exchange server doesn't always download the POP3 email, and then the users often sit without email until I go there to manually download the mail again.
I have tried changing the MX record to point to their DynDNS address, and it works well, but then they get a lot of spam. And the cost of a server-side spam solution is just too expensive, and they also pay for the bandwidth uses when spam comes in. So, I moved their MX record back to the Linux server. But now I sit with the problem of the POP3 connector failing from time to time.
So, I would like to know, is there a way to "push" (not forward) mail from the Linux server, after it has arrived and spam been blocked, to another domain, but with the same email address? i.e. the domain in question is attorneys.co.za and I've setup attorneys.dyndns.net as the dynamic domain, but the exchange serves email for attorneys.co.za Forwarding email doesn't work, since there's no such user as bob@attorneys.dyndns.net, but rather bob@attorneys.co.za.

Customer wants to move his website in-house along with his email. The hardware guy installed a windows 2003 64-bit exchange server. I logged in with logmein and created a directory c:Inetputwwwroot hewebsite. Copied iisstart.html to the new dir. Put the company name in the iisstart file. Opened IIS6. Went to properties of the default website and pointed to the new directory on the home dir page. Added iisstart.html the Documents page and moved it to the top. Closed everything. Opened Internet Explorer 7 and put in http://localhost. All worked well. Brought up the new start page. Opened IE7 on my pc and put there ip address in and it also brought up the new webpage (tested the port 80 in the router). Said we were ready to go.
The hardware guy sent me an email stating that he was having problems with the 64-bit version and took the server back to the 32-bit version of windows exchange server. I logged back in with logmein and followed the same exact steps as above but it will not show the new webpage. Am getting a page not found error.
I have done the above on several 2003 servers and several xp pro machines. Always works.
Have done one 2003 exchange server. Went to a couple of those servers and made sure the default website settings were exactly the same as the ones that work. Still no help.
Downloaded an iis6 troubleshooting program from microsoft but cannot locate the error. I have been studying the II6 documentation and 2003 exchange server documentation. Went thru all the tutorials in google on iis6 and exchange I can find no help.

Our company has recently invested in a Microsoft Small Business Server, we are moving all our email accounts to exchange server.
Our company runs a high profile website in Japan and we have a few email accounts that are downloaded by multiple staff, rather than have all staff download the same emails is it possible to have all emails forwarded to a public inbox where emails processed can be marked and ignored by other staff?
We do not want to forward the emails to user's personal inboxes, this seems to be the common solution for this type of email.
This might sound like a basic questions but we have trolled the internet for best practices in trying to set up this solution on exchange server but have not come across an answer.

I have a 2003 SBS server with about 50 users on exchange. It is a standalone DC - all the users connect with 'profiles' and 'docs' on the server and use exchange thru outlook..when they leave the office they VPN in and exchange works like a charm.
Problem is for a quick setup I've used the POP 3 connector and kept the emails hosted on my server - I want to get rid of the POP3 connector setup altogether and have mail delivered directly to the server.
Can someone give me a walk thru of steps to do this - so far I have fgured out that I have to add the domain to the recipient policy - configure it properly and then setup each user to receive email for that username and it will just work....
I want to be sure and was hoping that someone who has done the same thing could point me to an accurate tutorial of sorts.

I have built a server so I can co-locate it to be used for shared hosting. The specification is high, compared to most dedicated server offerings, so I was considering splitting it up into different virtual machines for different purposes. The specification is: Intel Xeon 3230 (4x 2.66ghz), 8GB DDR ECC RAM, Seagate Cheetah SAS 15,000rpm (4x 147GB), Adaptec RAID 5405 (RAID 6 Array with Battery Backup), Dual on-board NIC, etc.
The original plan was to use this machine as just one linux server, but I am concerned most of its potential will not be exploited. So I am exploring the possibility of setting it up as 2 Virtual Machines, installing Linux on one and Windows on the other. This way I can offer hosting for ASP and ASP.NET, and possibly MS SQL and/or Exchange depending on costs for their licences.
What Microsoft licences are suitable for servers used for shared hosting? From what I can gather there are several ways of being licenced, but I can't figure out which is the most cost effective. It seems you buy the server OS edition that supports your requirements, then pay another licence per user (CAL?) - I haven't got a clue how many users I will need to have though. Then if you want to use MS SQL, DNS or Exchange you need the correct edition - and buy licences for these too.
Does anyone know roughly what I should be looking to pay for what? I would ideally like to have MS SQL, DNS and Exchange - but am aware that the licence could be so expensive that it wouldn't be worth doing.

Have been receiving the following warnings for more than a day. Does BFD auto execute a permanent ban or do I have to do it myself? If so, how? Also, I did a whois, found out the service provider, and sent an email regarding abuse. I have yet to receive a reply.
I was wondering since its a HK IP, do I have to send the message in chinese? Would anyone be kind enough to do so?

My hosting with everity.com started at the end of November and beginning of December 2007 when I was having issues with Crucial web host and them blocking members on my site and a slow site as well I will not go back to Crucial for that reason and they more then doubled their prices.
Any way when I was having trouble with Crucial I looked into many hosts. I had a huge list only remember a few but now that I came back here am remembering a few more. A few off the top of my head are trexhost glad I did not go with them as they closed down, reliable site and ok hmm I forgot the rest but any way this review is about everity not other hosts. So one of the things that sold me on everity was the kindness shown to me when I was asking him questions. One of my questions was about semi dedicated as I was thinking that might be what I need. He had descriptions of it in 2 spots on his site and they were different so I asked him about that and if I remember right he said it starts at the lower one and you can get up to the higher one. But the thing he said that sold me was when he told me I probably would not need semi dedicated and would be fine on a shared. This shocked me as every other host I have talked to always tries to get me to buy the vps or semi dedicated.
So after he impressed me by saying that I got an account. He did a free site move and had to do it manually too as crucial disabled the back up feature. After every thing was moved he even made sure every thing worked on my site, some hosts only move you and do not make sure things work. He even joined my forum , the owner I mean.
Back in January I did have a minor issue where at midnight my site would not load. Opened a ticket about it and it was fixed in a timely manor I am unsure of what was doing it but glad its fixed.
There was an issue a week or so ago when my Arcade's tournament system was doing funky things and found it was from another site that had an open exploit that caused mine to go funny after that customer was contacted my issue was fixed.
A new issue one that happened today was with my gallery and it had stopped working do to mod_security being installed. When I contacted support he did offer to remove it but because it was added to prevent the above issue I told him just to leave it and I will re install the gallery. I do love the kindness he put forth in that ticket as well as all the rest.
Oh speaking of kindness in tickets I opened a ticket about being confused about his billing system as it was totally different then what I am used to but he explained it and even changed the wording on it to make it less confusing.

[url]- down right now do to the mod_security but am working on reinstalling it. just waiting for ftp to finish downloading the images.

I downloaded and installed this today thinking I'd build two VM sessions. one for CentOS and one for Ubuntu just to play around in.
But when I start a new session, choosing 'other' for the O/S, assigning plenty of RAM and hard drive space I still can't get to the setup.
Using the CentOS 5 iso I attempt to install. I get about 10 seconds into the load, and the system stops right after it sets the read only session on the kernel.
Using Ubuntu I can't even start. I choose to install text version, and i get two immediate CRC errors.
I've downloaded them both twice.
One other thing, I put my Vista disc in to test this (not an iso) and it ran fine.
Is it not possible to install linux from an ISO using this?

There is a strange problem with picking up and sending emails on Outlook 2007 which I have wasted hours on over the last week.
Whenever I try to pick up/send emails on domain names, I get a 800CCC0F error message. It says: "reported error (0x800CCC0F): 'The connection to the server was interrupted. If the problem continues, contact your server adminstrator or Internet Service Provider (ISP)'"
I have gone through all the steps here [url]and here [url]and on another websites.
I have been setting up email addresses on Outlook for several years, so know how they should be done.
The strange thing is the email addresses of domain names hosted elsewhere work perfectly. But both new and existing Clook-hosted email addresses are producing this error message.
I believe it may be an error with the software for two reasons:
1. The email addresses work perfectly when I open Outlook in Safe Mode.
2. Our web host's staff have not been able to find anything wrong and the email addresses work when they try to set them up on their computers.
Any idea why our email addresses may not be working and how I can fix this please?
I have tried System Restore and Repairing the program on my computer's Control Panel.
