Internet down, fixed by rebooting Windows 2003 DNS server, What are the DNS issues?
Posted on 2013-10-25
We have a domain that has 2 DNS servers that are Windows server 2003. One is the exchange server 2003 that also runs AD (DNS1) and the other DNS server is running DHCP along with AD (DNS2). Every few days I have an issue with all the computers connecting to the internet. They can't ping to the websites by name. The only fix is a reboot of the server. Even if I restart DNS services it does not clear the issue. DNS2 is a virtual server with 2 Nics, one attached to 192.168.1.x subnet the other to 192.168.60.x subnet. It is providing DHCP for both. I had to reboot DNS1 4 days ago to allow users to get on internet. Today I tried rebooting DNS1 and it did not fix the internet access issue, but a reboot of DNS2 did. Any thoughts on what is causing the issue. It has been sporadic over the last 3 months or so.
