Hmm, Greg mentioned to me earlier that he was suspicious of SSPI which seems to drag in dependencies on gdi32.dll and user32.dll via secur32.dll. Sure enough, testing with 8.2.5 on XP Pro, I get to 150 connections running as a service having used 97.2 of desktop heap (vs. 45 connections max with 8.3). So we have a pretty serious regression in 8.3. Of course, that still doesn't tally up with what you're seeing on Win2k3. I'll test on there tomorrow.
