Hi Richard, I've always felt that WinXP SP1 was ill fated, and I don't install it if I don't have to. But like you say, if you have an integrated SP1 in your XP installs, you've got problems. So, is XP SP1 your only problem? From what I can tell, the Outlook SPs tend to be a problem too. Thanks!

Windows XP SP1 Outlook 2000 (SR1 and up)/2002 (SR1 and up) Exchange server not inside a domain ISA server with/without FP1 I have fought this fight for some time. All is well until XP SP1 is put into the picture. Thanks to whoever sent in the information about the Reg hack for the GC (Q307926). It has finally fixed my access trouble. Everything was working fine until I installed SP1 so as far as I can tell this is the problem. My real trouble is that all the newer system have an integrated SP1 in the OS so removal is not an option.
