DNS diagnostic errors
Hi
We have some schools servers
Windows 2003, Active directory and DNS server installed.
We occationally get error messages in event viewer agains DNS Server
I downloaded windows 2003 support tools to use
dcdiag to test DNS Server.
To my big supprise it looks like its totally failing.
Can anyone have a look at this result file of that test:
It says that its invalid DNS Servers. They are bouth valid DNS Servers for TDC (provider)
It also gives errors to all the root hints and I am not sure why
Our DNS Server is setup as we are using Terminal Server.
Can anyone tell me if this is serious and if this might affect the stability of our server
I am totally new to DNS and got lost trying to read about it so if anyone can find some good easy documentations or som basic analyze what I need to do, I would be a happy man
Kind Regards
Morten
