Exchange 2007 - Cannot find GC in forest/domain

So, I had a bad DC a while back... ended up losing a LOT of my DNS (being ad-integrated, and suffering from replication problems).  Resolution there was to recreate the zone, and re-add all of my servers (registerdns, recreate static records, etc).

We'll say my domain is domain.fq.dn

I'm unable to manage my exchange server now.  The error reads:
Could not find any Global Catalog in forest domain.fq.dn

Checking the SRV records from DNS on the Exchange 2007 server:
nslookup
set type=srv
_ldap.gc._msdcs.domain.fq.dn
>>>>Returns 3 records, all correct.

repadmin /showrepl
>returns no bad information

repadmin /syncall
>returns successful results

replmon displays that all partitions are synced

setspn -L <server>
>displays a bunch of SPN records, both qualified and unqualified.

I've been searching the issue now for 3 days, without any luck.  My theory is that I've missed something... a srv record,

please restart your server and try

check event viewer
you should have an event 'adaccess'
in that you can see what are the active GCs and DCs

Odd... the first thing I tried when I was having problems was a reboot.  Seems to fix everything... didn't fix it then.

Did fix it this time.

Though, I do worry that it only listed 2 of the 3 DCs.  Do you think there's a replication problem (despite the replication tests listed above showing as successful?)

Primary DC is listed ?

It is not, actually.  It is also not listing the GC-DC that is in its site, and is instead listing 2 DCs that are out-of-site (if that matters).

If the primary DC/DNS is active/running and good

configure correct DNS and alt.DNS in the NIC properties
and
run this command 'setup.com /prepare AD'

I won't have a window to restart until this evening, but I'll post back when that is finished.

Turns out the problem was related to autodiscover DNS.  Problem resolved.

DNS entry was missing... re-added it and things magically are fine now.  Gotta love DNS issues.

FYI
Autodiscover has no role in discovering GC.

Could be DNS AD integration issue
