Does anyone know where I can get the MMC snap in for Exchange 2003 running on XP??? All I can find is the snap-in for Vista or Window 7.

Its supported on XP,: http://technet.microsoft.com/en-us/library/bb123850(EXCHG.65).aspx You can do a custom installation with the 2003 Binaries.

The links only apply to Vista and Windows 7. I've tired running both on an XP computer but it won't work because of incorrect .dll's. I used to be able to download for XP but it seems no one has the download any longer.

Use your ordinary installation media/binaries. But before you can install E2003 tools on your XP you have to install normal admin tools at first. Then you can perform custom installation from your E2003 setup and get the tools installed. If you have .dll troubles, double check the installation media.Petri
