I seem to be having some issues with my domain controller when trying to resolve hostnames using dns. It does seem to work but it always takes a couple of attempts, even if its a hostname i have already resolved. I have been noticing it with webpages and downloads.
Here is a nslookup test i did
C:\Users\chris.townsend>nslookup abc.com
Server: dc.example.com
Address: 192.168.101.20
DNS request timed out.
timeout was 2 seconds.
*** Request to dc.example.com timed-out
C:\Users\chris.townsend>nslookup abc.com
Server: dc.example.com
Address: 192.168.101.20
Non-authoritative answer:
Name: abc.com
Address: 199.181.132.250
Some sites it works first time and some it takes a couple more. I cant seem to figure it out and its the same on all the systems in our office. Restarting and /dnsflush dont seem to make any diffence either.
Can anyone suggest anything?
just incase anyone else has this same issue : this is what we found out it was – we use a watch guard router and it seemed to be proxies causing this issue
