socket based programs

Testing some software on Vista B2 that create sockets for network comm. These worked fine on 5308, but are failing here when trying to create a listening socket.
What might have changed to cause this?

Check your firewall, and group policy settings - these can both have problems with sockets etc.

Firewall is off. Will check group policy. Same components worked for 5308 but fail for 5384.

The firewall stuff is turned off. I have found nothing in security or group policy that seems likely to cause this. Basic connects to an active TCP/IP port on another PC is where it is failing.

Further testing seems to show a DLL difference of some sort between the two builds.
