My mail server sudenly lost connection to Global Catalog, and cannot reestablish it. On the list of "All domain controllers" the actuall GC is missing, i can see other domain controller though. "Global catalog" list is empty. Typing in manualy name of GC is not solving problem :(

GC however, as well as secoundary DC are passing all DCDIAG tests :/

Please help!

How do you know ? what alerted you?

Can you ping it ? are they in the same site

try "net use \\gcname"  where the gcname is the name of your dc.

I am not sure for what specific items, but exchange needs wins and dns.

if it does ping and they are on the same subnet look at the arp table - to confirm the macs match.

Thanks,
Mark

Outlook couldn't connect to  mail server. Mail server logs reported unable to connect to GC.

I can ping GC, i can browse it, I can even connect AD Users and Computers console to it. For some reason however mailserver doesn't see it as GC, not even domain controller.

I runned yesterday morning SECEDIT on that DC, as it couldn't refresh group policy for the past few days.

I thinking od demoting it from being DC altogether and promote it again?

Also, forgot to mentioned.

I worked around the issue, by enabling secondary DC as GC. Mailserver is using it now, and it's the only DC and GC it sees.

I have solved the problem.

I disabled GC on domain controller that exchange server couldn't detect, and re-enabled it. Mail server detected it after few minutes.

Thanks.
