Is this to what the which you are referring to in the afore mentioned DNS issue?

Wasn't XP really finicky about sticking to one DNS server, and if it went down, it didn't properly fail over to the secondary one? On Fri, Jul 5, 2013 at 11:46 AM, Andrew S.

As far as I could see DNS replication seems to be working. However, when querying certain things I discovered some problems. I was able to resolve all sites from the additional DNS server but not from the primary DNS server. I next looked at the DNS manager and when looking at the primary DNS server I am seeing Automated Test Query Failed message. When checking the System Event Log of the primary domain controller I am seeing 5774 Events (NETLOGON) being logged every day.

How is external DNS handled? Forwarding Servers or Root Servers? Was DNS replication working properly prior to the shutdown? Can you resolve all the sites in question from the DNS server? Any eventlog messages? Regards, ASB http://XeeMe.com/AndrewBaker<http://xeeme.com/AndrewBaker> Providing Virtual CIO Services (IT Operations & Information Security) for the SMB market...

I cannot understand why this should have happened. Any idea why this happened? Thanks Pierre
