Exchange 2007 Kerberos
Oct 24, 2009
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 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?

I'm trying to do a setup of alfresco.It has two basic sites. [URL]. Both use kerberos authentication. Alfresco has SSO and share has not. Both sites are on the same server (its just one site but different subs)
I want to put this behind a reverse proxy to eliminate the servername:port combination.
When I put it in a normal config with ajp everything works fine for the share website. I can login without problems. Not so however for the alfresco website. I get a browser login request (not the alfresco one) when i enter my credentials he asks them again and again and then he ends on the regular login page of alfresco at which point everything works. The username I entered is displayed at this point. When I do not enter my credentials correct I do not reach the page.
If I remove the SSO from the alfresco website everything is normal (but i have to login)

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.

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?

Windows Questions
I WILL be install WS2003 EE R2 on a dedicated server.
However, I will make this into a DC/AD so I can install Exchange and serve the system as a Webserver. All that's fine
But the question during the creation of an DC props up.
I have 2 domains. I will also have 2 dedicated IP's.
Now, lets say I have domains www.aaa.com and www.bbb.com
1) Would I Install and configure DNS on this server? Remember, this is a dedicated server located in a datacenter somewhere with their infrastructure in place.
2) Would I need to configure anything in the LAN settings? Should I just leave everything to automatically detect IP and DNS Servers? (No other computer will be joining this domain)
anything else I should be aware of?
ok, now I have those domain names, I would need to update the DNS Records from the web hoster right? So I would need to update the NS records (The place I purchased the domain from)
Exchange
Now, since I will be creating several user accounts here, these user accounts will be for email addresses.
1) Is it possible to have 2 domains on this 1 exchange server? I'm guessing not? (I dont have knowledge about exchange)
2) What about configuring an exchange server? How would I say create an email address like "abc@aaa.com"? So this email account would then be able to send/recieve email?

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:
Spot Marketing on 1/11/2008 12:39 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail.uaminc.com #5.7.1 smtp;550 5.7.1 Unable to relay for **@spotaviation.com" ******@spotaviation.com>
The following recipient(s) could not be reached:
*****@Tracercorp.com" ***@Tracercorp.com on 1/11/2008 9:24 AM
There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator.
<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.

I've seen various companies offering Microsoft Exchange hosting but I'm not sure if this is what I need to go with or not. Let me explain what I'm wanting to do and maybe someone can give me a yay or nay on it. I have a desktop and a laptop running Outlook that I would like to be able to sync together with a web-based server. I also have a Treo 750 cell phone that I want to have my calendar and tasks synced as well with the web-based server.
For example: I add an appointment on my desktop computer and it syncs with the web server. When the web server gets it, it syncs to my cell phone via ActiveSync. Right now I'm using the free version of Mail2Web which doesn't support Outlook syncing. (I have to manually enter the data on the website interface and then it will sync via Activesync to my phone.) They do have a paid version starting at $11.95/mo that will supposedly do what I'm wanting to do with Outlook, but I'm not sure if this is overkill for what I need or not. Again I don't really need to sync email, just my calendar and tasks.
So do I need a full blown exchange hosting provider or is there some software (other than Exchange) that I can install on my Windows VPS that will do what I'm looking to do?

I have a slight issue that some of my emails are being converted to a htm file and attached to the email. I am using exchange server and outlook.
For example if I received an email and it was converted into a htm file and the body of the email was deleted so only the attachment existed which included the email.
There is no trend to this as sometimes it happens and on other occasions it doesn’t.
Besides this when I receive a read receipt many of these are converted to a normal email. I know this can happen from the senders side but I know for sure that some of the read receipts received should include outlooks read receipt icon although this is not happening. Is this something to do with exchange or my outlook installation.

I have a client with SBS 2003 and exchange. They had a bad HDD (it held the exchange .edb and .stm files).
I installed the new HDD, configured Exchange to use the new HDD for the files but I did not mount it when it was done because I was in a rush.
I came back into their office first thing in the morning and mounted the volume. However, they did not get any emails during the night.
My question is: The emails that were sent to them, are they gone forever? Did they get bounced back to their senders? If not, can they be recovered?

I'm currently with 1and1 - obviously they suck - no need to belabor that here. I've been resisting a hosting switch, but the outages are more and more frequent, and my website is my livlihood. Need recommendations for web/MySql hosting and also hosting for a single Exchange account. Does not have to be the same company. Price is not a huge issue - I'm willing to pay for quality. Requirements are basic; about 3-5 GB of file storage, SQL 4 and 5, linux server. Shared server is fine. Any recommendations? Don't really trust the "review" sites.
Some kind of moving assistance/support would be GREAT. I've managed to muddle through and set all this stuff up over the years, but am not at all confident of my ability to move it all without screwing up. Includes 3 active databases, several sites, SSL cert (currently purchased through 1&1 but it looks like they farmed it out to geotrust), and exchange mailbox.
