How To Block IP Addresses In Windows 2003 Server - Software Firewall
Jun 18, 2007
I am running windows 2003 server.
Recently, there have been brute force attacks to try and compromise my sa password (MSSQL) and root password (MYSQL).
I would like to block certain ip addresses, but looking in the built in firewall in windows I don't see a way to do this. Is this possible with the built in tools/firewall that comes with windows 2003?
If not, can anybody recommend a simple firewall solution that will allow me to block ip addresses? I don't want something that is bloated and blocks popups, viruses, adware, etc. I just want a solution that will allow me to block ip addresses and prevent brute force attacks.

Recently our windows 2003 server, running Microsoft SQL 2005 has been the victim of brute force attacks on the MS SQL admin account. They are unsuccessful, but its annoying all the logged entries in event viewer and the extra stress they are putting on the server asking to authenticate 25 – 60 times a minute.
It comes from the same IP addresses. Is there a way to configure a software fix to block these ip addresses completely from the server? We are running a Hotbrick NAT router, SPI firewall but to my knowledge there is no way to configure an individual IP block with it. Here is link to the specs on the Hotbrick we have:

I found out the ips that were being used to attack my server, but I don't know how to block them. My provider (Limestonenetworks) will not block them from the main router because they don't believe in blocking traffic. Is there a way I can run a firewall that could block the ips? The windows firewall does not have an option to block ips. Last question, if I was to install a 3rd party firewall, it won't lock me out of the server right?

can anyone recommend firewall software for Windows 2003 Server. I'm aware it has a firewall on board, but this one doesn't allow me to specific access to specific IP address on the server, which are configured on a single adapter.
Also, I've looked into IPsec, which is my backup solution if I cannot find a decent firewall. Unfortunately, IPsec is kind of restrictive and not particularly stateful.
I'm looking for a simple firewall, which is not too expensive. This is only for one simple server.

I have Windows 2003 Server on my dedicated server...
PLESK 8.1
When I go into the Control Panel -> Windows Firewall.
It won't allow me to open Windows Firewall to configure it.
I get the following error....
"due to unidentified problem windows cannot display Windows Firewall settings".
I have checked PLESKs control panel. And there does not seem to be a service in there for Windows firewall.
My Host suppose to have contacted PLESK about this problem but they are taking far to long to resolve the issue.

First of all, I am from Australia. Some people might know here dedicated servers cost a lot coz bandwidth is extremely expensive. I am hiring a box to put dedicated game servers on them (Counter Strike Source). I am looking for a Windows Firewall and Anti Virus. I am also wondering what version of Windows 2003 server should I get. Do I need to get real time protection and email scanner? And also, is it wise to download and browse TRUSTED sites on the server?

good software firewall solution that will allow me to block certain IP addresses from all ports.
The problem is that, the only way I have access to the server is via remote desktop. I found when you install almost all software firewall solutions, that it requires a restart. The problem here is that after the restart I probably wont have access to the server via remote desktop because it will be blocked by default by the new software firewall.
What is the solution? How do I install a firewall solution but have access to the machine via remote desktop by default?

The subject pretty much says it all. A simple implementation / reversal is what we are looking for.

With Windows 2003 server, there are comprehensive lists of what you need to do to secure the server before use. For Windows 2008, I wonder is there such a list? Or is it true as what I heard from Microsoft that it is already secured out of the box?
Anyone has any resources on the hardening or preparation of 2008 for server hosting uses?

Server: OS RHEL 4
Web Server: Apache1.3.37
Hi. I want to block a range of IPs. Currently, I use the following command as an effective weapon against the IPs of people I find in the log trying to do bad things.
/sbin/route add -host x.x.x.x reject
Works like a charm. I then put the offending IP in the file /etc/rc.d/rc.local so that it will reload the bad ips when the server reboots next.
I also use the CSF/LFD firewall, and it successfully blocks single, offensive IPs also.
What I need, though, is the ability to block an entire range of IPs. For example, i have a very persistent hacker trying to access from a certain range like so....
255.155.x.x.
The last two numbers are always changing but the first two remain the same.
How do I block this "range" of IPs from accessing my server?
Note, I know how to block a range of IPs in a .htaccess file for a certain account, I put this in the .htaccess file...
deny from 205.196.
But when I try this with /sbin/route, it will not accept the ip. My firewall will also not accept a range of IPs.

This is my first dedicated and I am plugging away at it.I am running windows server 2003 web edition and I have my database, website, and ftp setup and everything is working so far. Now if you go to 66.96.196.102 my site that I'm working on will show up. My question is my domain and site that I am in the process of moving is hosted on a shared server on 1and1. Now I need that domain to point to that ip. Do I need to set up name servers on the server? If so can someone point me in th right direction.

We have two Windows Server 2003 machines as active directory controllers and DNS servers for our in-house operations. For our purposes, let's say the domain name is example.com.
Both servers have DNS, and example.com is stored in Active Directory to allow us to use the benefits this provides. Our issue is probably simple, but I'm not sure how to fix it.
Let's call server one EX1, and server two EX2. These have local IPs of 192.168.1.111 and 192.168.1.112, respectively.
We want example.com to be resolved to an external IP address (for web hosting), let's say 1.2.3.4. The problem is, the two domain controllers keep registering example.com with their internal IP addresses .111 and .112, so the DNS round-robins between 1.2.3.4 and the two internal servers, which aren't web servers.
Is there a way we can get those DNS controllers to stop registering their internal IPs as example.com?
