TCP issues

[Guest]

I am trying to troubleshoot an issue with TCP socket communications between a
Win2003 server, and a Win2000 server. The 2003 box is acting as the client
in this instance, and is sending SYN requests, but the 2000 box sends back
RST SYN. Anyone seen this before, and if so, is there a fix?

How are you trying to connect? SMB? Try disabling the requirement for SMB
signing on the W2K3 server. Or make sure it's at least at the "if required"
level on the W2K box. Should work if set at the defaults. If not SMB then
what is the session layer protocol?

We have a proprietary app that manages the session layer protocol. From what
I can tell, it is running a standard pdl minimum TCP protocol

Can you make other TCP connections? How about FTP?

The unusual thing about this is that when the Win2003 box is acting as a
server in client/server config., it seems to work fine.
