Our company currently using a Windows NT 4 Server PDC and 4 others NT 4 BDC. We have to install a new Windows 2000 Server and 5 Windows 2000 Professional PCs. I wonder the windows 2000 server can act as a BDC in our NT Server network. Also, will there any communication problem between NT server and 2000 server, especially NTFS4 and NTFS5. Thanks!
