In our company we had a PDC and a BDC both running Windows NT Server 4.0. Recently we upgraded the PDC to Windows 2000 with Active Directory. The BDC is still running 4.0. The problem we have is that Windows 2000 users are taking up to approx. 1 miunte to logon.

If you upgraded, I will bet that you are running an older, slower server. A server that is not at least 500mhz Pentium III does not work well with either 2000 or active directory.

On the desktop, Windows 2000 also has to be 200mhz faster in speed to equal Win 95/98 performance, and about 100mhz faster than N/T 4.0.

Desktops have to be at least 500mhz Pent III with 64 gig ram to get reasonable performance out of 2000...Celerons and Pentium II's do not work well with 2000.

Your network also has to be at least 100 base-T switched. (a 10 base-t or a 10/100 will not work well with active directory)

If above ok..the next step is to make sure the server has enough memory and processors to support your number of users. Add 15 to 20% for N/T to 2000 conversion. If it is a single processor....forget it with 2000.
