Hello Experts,

I have a strange issue with my firewall/DNS
Whenever I restart a computer and try to connect to the internet i am unable to.
This is the message i get on the Firewall Logs:
2      Nov 10 2010      09:53:11      106007      10.60.3.20      56153      DNS            Deny inbound UDP from 10.60.3.20/56153 to Server/53 due to DNS Query

In about 10-15 minutes the internet will start working. But in the mean time, I will keep getting that message non stop.

Any help would be appreciated.

Thank you!

Are you hosting a DNS server in house at the 'Server' host?   Or perhaps some kind of dns 'caching' at 'Server'?
