32-bit edition of the Windows Server 2003 Global Catalog required for Exchange 2010?

    Question

  • Is this for real? "In every Active Directory site where you plan to install Exchange 2010, you must have at least one global catalog server that is the latest 32-bit edition of the Windows Server 2003 Standard or Enterprise." Systems requirement also state that the Schema Master has to be on a 32-bit Windows Server 2003 Standard or Enterprise. I have just about all my DC's on 64-bit 2008 looking to go 2008 native. Please tell me this is old info.

  • No, your domain controllers can be 32 or 64 bit.   I believe that documentation has yet to be updated.

  • And just to confirm, I just checked my lab and I have 2 x64 2008 domain controllers (one full, the other server core).

  • Keep in mind if you only have 32-bit DCs then you won't be able to things like extend the schema. You'll need at least one 64-bit DC to do that stuff on and make it the schema master for that period of time if it isn't now, then you can switch it back after. :)

    *edit*

    Someone fact-check me and make sure setup.exe has to be run directly on the schema master. :)

    Setup does not need to be run from the schema master, you can have a 32bit schema master and run the update from a seperate 64bit computer.
