I have an app that runs fine on my development pc but does not run on target pc. Both are XP-SP2. The program was built using VC++ 2008. I linked as static without CRL or ATL. The gui portion works on both pcs, but on the target pc it will not send UDP packets over sockets. Any ideas of what to look at? I am not even sure what code to provide since no errors are being reported. I can provide some if when we narrow down the possibilities..
