Unable to join Windows NT 4.0 Server BDC to Windows Server 2003

Unable to join Windows NT 4.0 Server BDC to Windows Server 2003

Post by Rick Kingsla » Thu, 10 Jul 2003 04:40:14


We have checked the security on the DC and disabled most
of the settings for the domain controller.  Still does not

Any other suggestions?

Thank you.

1. Use Windows 2003 server as a Windows 2000 server

I have two trial CDs for Windows 2003 server, 1 standard and 1

I would like to use them as though I am using Windows 2000 servers,
because I am uncertain what new unexpected features are in Windows
2003 and may want experience on Windows 2000 like setup. Unfortunately
I do not have trial versions of windows 2000 server.

Any one have tried similar things, and if so, share the experience?
