Exchange 2007 - The Exchange  topology service did not return a suitable domain controller

Hello,
I am having an issue with my exchange 2007 SP1 server. The entire office environment runs on server 2003 standard.

I have narrowed the problem down to the exchange server not "seeing" any AD servers in my domain. I can ping from my email server to both my DC's and there does not seem to be any DNS issues as everything is resolving to the correct IP's.  I keep getting the following errors in my event log on the exchange server about every minute:

Look up the Lightweight Directory Access Protocol (LDAP) error code specified in the event description. To do this, use Microsoft Knowledge Base article 218185, "Microsoft LDAP Error Codes." Use the information in that article to learn more about the cause and resolution to this error. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers.

Process IISIPM1DED805F-6588-48A0-9D04-A8CA72C32C41 -AP "MSEXCHANGEOWAAPPPOOL (PID=5844). Exchange Active Directory Provider has discovered the following servers with the following characteristics:
 (Server name | Roles | Enabled | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version)
In-site:
AD1.FQDN      CDG 1 7 7 1 0 0 1 7 1
AD2.FQDN      CDG 1 7 7 1 0 0 1 7 1
 Out-of-site:
 
So from I see the topology service sees the AD serves but is not reporting them as suitable for the other MS exchange services to use so many fail at startup including the exchange transport service.

Looking further into the logs i also find these two events which point to an account problem in AD but I cannot find any problems there.
