Is it possible to block all outgoing connections from a port on Windows Server 2003? If it is not possible by default, is there a firewall program that can block outgoing ports?

Yes,several ways, but the best way is using IPSec See here how to accomplish it: How to block specific network protocols and ports by using IPSec

I ran this: IPSeccmd.exe -w REG -p "Block UDP 29910 Filter" -r "Block Outbound UDP 29910 Rule" -f 0=*:29910:UDP -n BLOCK and it says command executed successful, but when I run: netdiag /test:ipsec /debug it says that there is no policies or blocks setup.

Is the IPsec Policy Agent service started?

I can't get on to the server now, but there was an IPSec service running but it was not called IPsec Policy Agent. IPsec Policy Agent was not a service in the list. This is what I did: 1. I downloaded Windows Server Support Tools and Installed. 2. I downloaded Windows XP SP2 Support Tools and installed on my computer and copied IPSeccmd.exe to the server since I couldn't install XP software on Windows Server. 3. I ran that command in command prompt.

Hi, You can run the following command to check if the IPSec policy has been created: ipseccmd show all Normally, you should see the policy in the Local Policy section.

Hi Joshua,I would also like you to check the inbuilt firewall / windows firewall.b) you can also use software firewall called ISA firewall / forefront server to block a specific port from a specific IP address but as Joson, shadowman mentioned you could rely on IPSEC. sainath Attending Microsoft Teched 2009

What exactly do you need me to check in the windows firewall? Hi, You can run the following command to check if the IPSec policy has been created: ipseccmd show all Normally, you should see the policy in the Local Policy section. I did that and it says no policy assigned, even though I ran the command to block the port.
