DNS Issue on SBS 2011

Hello,

I have a SBS 2011. I have issues with the DNS - on random bases it just stops working properly. Some websites are opening, others are not. After restart of the service - it works like a charm. To solve the issue I created a batch file to restart it every 4 hours. However the schedule is working fine, but the issue persist. It is gone only after a manual restart of the service.

Any help, please.

Your application might be leaking memory. Check the event the event viewer of any error.

Also, you might need to use IIS debugging tools to get any crash dump for analysis.

Hi,

Are you able to open security website like symantec, sophos or microsoft? this may caused by virus. Worth to perform a full AV scan on the server. Also, have you changed your forwarders recenly or is this configured correctly?

The website you are unable to access, are you able to ping them?

As Cliff points out, this is a well known issue.  you can either do the registry fix as pointed to or simply add DNS Forwarders
