I recently set up a new server with W2K - made it a domain controller - then upgrade to 2003 - ALL the proper steps per the Microsoft KB and other suggestions here. I have a W2K member server running Exchange 2000. I also ran the script to avoid mangled Attributes. I also have the another DC running W2K - On the new server everything is replicating and in holds the FSMO roles and is a GC. My question is what do I have to do to get the Exchange tabs to show up on the 2003 DC?
