Have a client running Server 2008, that every day around noon, no one can print. No other problem with the network. After about 1/2 hour people can print again. Resources are fine all below 20% untilization. Check the Event Log and see that everyday at 11:50 AM there is a DNS error, Event ID 5782. "Dynamic registration or deregistration of one or more DNS records failed with the following error: No DNS servers configured for local system.
Thing is the server does have DNS running on it, so not sure why it's getting that, AND could this DNS error be causing some weird timeout thing with the print spooler?
