Re: Domain Controller

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi,

That's the gist of how it works, but if I remember correctly, in Windows
2000 native, if the DC that was down was a GC, a user logging on would need
to obtain Universal Group Membership from a GC before they are authorised to
logon. If there was no GC left in the domain to contact, this might be why
your user was unable to logon.

I believe this was refined in Windows 2003, whereby a DC would cache
Universal Group Membership if enabled so if a GC was down, a user could
obtain a current cached listing from the DC and mitigate the requirement of
contacting a GC.

If you domain is single, might be worth making both DC's GC's.
