Nightmare logon time.

Hi everybody,

All of the computers in my company last month are in windows 98SE, windows 2000, XP and netware server 3.12. Last week I have changed the server to windows 2000 domain and I see that the computer with 98SE login the the domain very fast(10 seconds) but the computers with windows 2000 pro or XP pro login to the domain very slow (~3 minutes). Many of my users feel very uncomfortable.

If any one know how to speed up the logon process, please help me.

Thank you very much.

Regards,
Quoc.
