couldn't telnet exchange 2010 server and now cannot start IS, lots of event errors

Hi, I have a 2011 sbs running exchange 2010.

earlier today the SMTP seemed to stop in both directions. Playing with it now, I have stopped all exchange services and cannot start the IS.

Originally the exchange trouble program reported port 25 couldn't be used and to check the local ip, etc.

I've run a dcdiag and  have found errors to do with the AD in some cases, please see a snippet of the report

 Starting test: NCSecDesc

         Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have

            Replicating Directory Changes In Filtered Set
         access rights for the naming context:

         DC=ForestDnsZones,DC=domain,DC=local
         Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have

            Replicating Directory Changes In Filtered Set
         access rights for the naming context:

         DC=DomainDnsZones,DC=domain,DC=local
         ......................... 2011SBS failed test NCSecDesc

Also getting in event viewer

event 1121 - Error 0x96f connecting to Active Directory.
event 5000 - Unable to initialize the Microsoft Exchange Information Store service.   - Error 0x96f.
event 2102 - Process STORE.EXE (PID=15832). All Domain Controller Servers in use are not responding:
2011SBS.domain.local

also attached is a full dcdiag log

SBS blocks the local network from using port 25 by default. Therefore that wasn't probably the original issue.

Run the fix my network wizard from the SBS management console to begin with.

You are getting some network issues - running the fix my network wizard could help resolve those. If there are issues with SBS communicating with the domain controller (on itself) then Exchange doesn't start.

I get the dns server is not listening to the ip address of the primary network adapter
I click fix, which it claims it has fixed. Rerun the program again and this issue still appears.

it also lists  dns is using a dns forwarder

the primary DNS on the adapter is the server itself 192.168.1.5

the DNS forwards are
192.168.1.1 - router
ISP DNS server

rang Microsoft in the end and discovered that avg may have messed up the replication service and also the transport queue for exchange. one we had remove AVG and sort out the problems, all worked fine.

Now I need to find another antivirus file server program to go on the server.

any recommendations.
