I have a client that I am installing a new Win 2000 DC with a BUDC & Exchange server. But I am having problems getting the workstations to log into the DC.... It comes back and indicates that the DC cannot be contacted of the UserID/PW is invalid. The client has 3 locations over a cisco WAN 4500 & 2-2500 routers. Any ideas??

Windows 2000/Exchange 2000 combination should work fine, but Windows 2000 as a DC and Exchange 5.5 can give you trouble. There are two reasons:
1. Windows 2000 uses LDAP to locate DC services. Exchange installs its own LDAP on the same port (389) and then you have a clash. To correct this, try to change LDAP port on Exchange 5.5

2. If you use Internet Mail Connector (IMC), then you have similar problem. Windows 2000 can have SMTP service running (usually for AD replication across sites). Exchange 5.5 installs it's own SMTP service. Try to disable SMTP on WIndows 2000 (if you don't use replication across sites).
