Our existing setup is as follows:
Windows NT 4.0 Domain Controller with Exchange 5.5 for Email. We have
3 sites each has its own Domain Controller. Each site is linked to
each other via 64K DDN and Trusted to each other using Windows NT 4.0
trusted theory.
SharePoint is installed on a Compaq ML 570 box with Windows 2000 Adv.
server as the OS of the box with SP2. This SPS Box is configured to
be a member of the Domain.
SharePoint works fine for all the users in the same site ( Same
Domain), but users on other Domain Controller cannot access the
Sharepoint, but they can access other application on the same server.
