I have had the following scenarios occur since I installed this 2008R2 Foundation Server:
1. The server and clients internet goes down. All intranet activity is great.
2. The clients internet goes down, but the server's doesn't.
Both can be solved by restarting the DNS Service.
This is happening at least once every day, at random times. I've applied a hotfix I thought described my problem, added registry entries, and still, it goes down.
Short of scheduling a restart of the service a couple times a day, I am stuck.
