Re: AD global catalog server query delay in application.
If there is a local GC, then the app should be able to find all the AD
information that it needs at LAN speed, as the GC holds a copy of all
the domain objects. (note: the domain,not the forest or other domains in
the forest, if its bigger)
You won't be able to figure this one out without being able to do some
digging I'm afraid.
Universal Group membership may help if your users would experience
delays because of security groups needing to be checked at a remote DC.
I wonder though if it would solve this issue.
rather than attempting different things to hope & find a cure, the
better approach is to try & understand what is going wrong & find the
bottleneck.
As mentioned this would involve some 'hands-on' work, for example with
process explorer (sysinternals) and or wireshark.
Would it be possible to reproduce the problem in a lab environment?
regards,
Paul
