Windows Server 2003 (Standard) Firewall Issue

There's a vendor application that needs TCP Port 1935 open on the network firewall- which it is. I can capture packets and see the data flowing. However, when it reaches the server, the server resets the connection.

The built in windows firewall on the server does not appear to be active and I dont even see any security software installed. I even checked Add/Remove programs. All there is a Symantec System Center MMC, but no software.

I'm afraid to enable the Windows Firewall because it may prevent current operations from occuring.

I was considering creating a group policy to enable the port but with the firewall apparently disabled, I wasnt sure that was worth trying.

Any ideas? Thanks in advance.

Does the server have ISA/TMG client installed?

No sir. It's an app server within a Small Business Server 2003 domain.

Hi,
Take a look of this...

Perhaps MMC enable it's own Firewall and/or it's detecting false-positive on the TCP/UPD traffic.
Check this...

Also install MS Network Monitor to see the traffic flows and to see that's blocking it.

Thanks for the suggestions, they helped to determine that the problem was with the application itself and not the data flow.
