Exchange server can't detect GC
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!

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.

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,
