Exchange 2007 Information Store will not mount

Information Store and Service host services will not start.  Transport service is in starting status.  All other Exchange services are running.  Rebooted the server a couple times.  Event ID's showing up are:  2114, 2080, 1000, 7005.  Seems they are related to Exchange not able to communicate with AD.  Not sure what to do?

Have you checked, is your domain controllers are working fine or not. As you mentioned the event codes it is clear that there is some communication failure of your exchange server to active directory server (DC/ADC). First check your domain controllers by following commands and post the result.
DCDIAG /V
DCDIAG /TEST:DNS

Also run exchange best practice analyzer and post the results.

See dcdiag file below.
Exchange is installed on a DC.
EVENT ID: 2114
Process MAD.EXE (PID=2000). Topology discovery failed, error 0x80040a02 (DSC_E_NO_SUITABLE_CDC). 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.

EVENT ID:2141
The Microsoft Exchange Replication Service attempted to start the RPC server but failed because an error occurred when attempting to read the Exchange Servers Universal Security Group SID from the Active Directory. Error message:
The Exchange Topology service on server localhost did not return a suitable domain controller.

EVENT ID: 1003

Thanks for the points, out of interest did you have SP3 installed?

WebccAuthor Commented:
No I did not.  Was trying to install as a solution but was not successful because some of the services would not start.  However, as soon as things were resolved I was able to load sucessfully.  Thanks again.

So did you have to resolve the DNS issues first or once tcpip6 was disabled things started looking good/better? Or did you disable tcpipv6 and then sort out the DNS issues to get the exchange services to start?

Disabled IPV6 and then DNS.  There was no A record for the server although it was complaining about AAAA record so I added one.  First I deleted the zone and created a new zone then added the A record for the server.  When I was trying to install SP3 initially it was giving me DNS errors.
