To all you Exchange 5.5 Guru's out there: I need to upgrade my Exchange 5.5 server which is a BDC, running on WNT 4.0 sp6. I'm upgrading the network to W2K Server. I need to downgrade the Exchange Server 5.5 BDC to a stand alone machine, (so I can upgrade our network to a Native Mode W2K network.) If I leave the Exchange 5.5 Server BDC box exactly as it is, what will happen if I just install Windows 2000 Sever directly on it as it is? Will I be given the option to downgrade the BDC? Or make it a stand alone unit? Thank you much! Jared __________________________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo http://search.yahoo.com
