We recently migrated all of our machines to Windows XP SP2 (windows-only environment) from having a novell client environment. One thing we have noticed, and just for the record we have Windows XP SP2 before on some machines, but not all, so when people are doing a lot of copying and pasting, the paste function stops working. We have received several TIDs including people using MSTSC, but the majority of people are seeing the issue on their normal machine (same machine as before, doing the same thing) and the paste is indeed hosed. They reboot and all would be good for a little while. We found a hotfix, loaded that and it still does not seem to make a difference. We have Dell machines wil 1 or 2 G of memory. Several people have reported using other tools at the same time for example SQL Server Mgmt Studio 2005, AD MMC console with Outlook and Word open. It is all over the board. It almost appears to us that there is a memory leak. Is there a utility or something we can load to figure out what might be causing this. Or perhaps, the 50 others I see having the issue on google, what type of fix they put in place. Rebooting several times a day is not an option for people and we will not be going to Windows XP Sp3 soon. Any help would be appreciated. Thanks.
