DNS Server issues

I have a client where we have to restart the DNS service every weekend for a few months.  What would cause this?  I have removed the forwarders from the configuration to see if that is causing the issue but I don't think it will.  Users can't log in during this time.  I guess I can have a script to restart the service every week, but would like to find what is causing this.  The OS is Server 08 R2.  Anyone else had or have this issue?

Do you have anything strange in the event logs when you experience this issue?

Does DNS respond to any requests while you are having the issue?

Maybe try an nslookup next time this happens to an internal resource to see if DNS replies, then try an external resource and see if you get a reply.

Is there anything showing in the event logs that isn't there after the restart?

Now since you have to restart it every weekend (I'm assuming not during the week), what, if anything is running or happening before the system goes into state?

Backup jobs, batch processing, etc.
What exactly are the symptoms that are causing you to restart the DNS server service?  When the trouble occurs, can you resolve internal host names/websites? External host names/websites? As others asked, are there any events in the logs indicating a specific problem with DNS?

It had Active Directory integration which I removed,  Seen errors in the DNS logs during the time of the issues.  I will have to see if this resolves the issue. I will update.

AD integration should not be the cause of this problem.
After removing the AD integration for DNS, there was no more issues.
