DNS problems

I am running SBS with Exchange and I am having some DNS problems. It just started a few weeks ago. We run SharePoint Server on another 2003 server with many virtual sites. People out side can only access these site if I go to the SPS server and repair the network connection. In the event log I have the error:

The DNS server timed out attempting an Active Directory service operation on DC=acct1,DC=AmyxDL.local,cn=MicrosoftDNS,DC=DomainDnsZones,DC=AmyxDL,DC=local. Check Active Directory to see that it is functioning properly. The event data contains the error.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Once again you go to the Microsoft link and it tells you very little. I checked on the event # 4016 and found this:

4016
MessageId=4016 Severity=Error SymbolicName=DNS_EVENT_DS_LDAP_TIMEOUT

The DNS server timed out attempting an Active Directory service operation on %1. Check Active Directory to see that it is functioning properly. The event data contains the error. Caching problems

Should I clear the cache??
Thanks for the help

Hi dwarren0940,

Did you add your additional server to the SBS network according to the prescribed method? Generally the failure to follow this procedure is the cause for DNS issues. Please see: http://blogs.technet.com/sbs/archive/2006/02/16/419784.aspx

Have not changed or added anything. All the servers have been up and running for 2yrs. This problem just started a few weeks ago.
