I'm trying to figure out an issue that my coworkers and I have come across. We are running XP Pro SP1 with Office 2K. When opening up an e-mail with a large attachment (3MB PowerPoint), it takes about 3 minutes to open. If we test this on a NT4.0 SP6 or W2K SP3, the document opens in about 30 60 seconds with the same e-mail. Anyone have any idea what could cause this and what a possible fix is? Thanks in advance for everyones help.
