Hello,

I have a domain D whit 2 sites A and B. There are 2 DCs on each site.
On A there is the PDC (W2K SP4)
On B one W2KSP2 and one W2K SP4

Today the link between A and B has been cut and the users on B have never
been able to open a session on D, although there 2 DCs on their site and well
replicated.

Where could be the problem? The configuration of the DCs on B seem to be
correct.

Thanks for help.

Max

How your DNS resolution is set up in site B? Which DNS server is configured
on all your workstations?

Also, verify that all domain controllers in site B are correctly registered
in DNS (srv records), since clients use DNS to locate DCs.

One DC on B is DNS server and is configured on all the workstations on B.

The 2 DCs are in the DNS but i'm not sure to understand what is a srv record?

Thanks

OK, you have a DNS server, but is it able to resolve queries related to your
AD domain? For example, does it has a copy of appropriate domain zone for
that domain, or does it set up for appropriate forwarding?

About SRV records - you better read some documentation about them.
Basically, each DC registers a number of specific records in DNS - called
SRV records because they allow clients to find service location. By
"service" here it is meant services required for ldap search, kerberos
authentication, global catalog and such; "location" means the hostname of
appropriate server and tcp and/or udp ports where this service can be
reached.

Any computer that is a member of domain will use DNS to locate domain
controllers; if appropriate records in dns are missing or incorrect, it will
be impossible to locate DC at all, or, incorrect DC will be used. This might
include DC from a remote site, but since in your case remote site is not
available, no DC is found.

At least one of the DCs in Site B should be a Global Catalog
server. Is this so?

Cheers,

OK all domain controllers are registered in DNS (srv records), but no DC on B
was GC...
I hope it was the problem, but it's difficult to test since I need to cut
the link between my 2 sites.

Thank you!
