VC6 and VC2008 Socket Compatibility

[vipergt023]

Hi,

I have an VC2008 (C++) app that reads data from a VC6 app using CArchives
over sockets using regular socket reads. On my local computer when I send
the packets to 127.0.0.1, it reads it with no issues. On a blank "test"
computer with .NET 3.5, VC++ redist, and both applications installed, the
local (127.0.0.1) test doesn't work. The VC6 app simply cannot detect the
open port of the VC2008 app. No error messages on the VC2008 app. Are there
some extra libraries that need to be installed? I'm pretty sure if I install
VS2008 on the "test" machine, it'll work, but that defeats the purpose.

Thanks!

Is there a difference in the firewall set-ups of the 2 computers.

I checked that, made sure Windows firewall was disabled. No other programs running (e.g. Symantec, McAfee). I have a test program that is written in VC6 that communicates fine using the CArchive across the network with different computers.
