SOLVED - ran Wireshark to see what exactly was going on at the packet layer. Looks like the client was requesting info from InstantMedicalHistory.... that was an old service we had installed, but I did not reinstall it since we no longer used it. I didn't do the original installation, so I was unaware there was a integrated piece for that turned on in AC. Turned it off on the server, restarted AC, Windows XP clients now open charts immediately.
Wooh!
Thanks everybody for your help and encouragement!!!
@Bert - did try to move the PC first and direct connect to server, no luck.
@stylnchris - the devils in the details. I just read that if the average user actually read all of privacy policies they agree to alone they would spend 1 month out of the year reading privacy policies.
