DNS not auto Detected on client machines

Afternoon

 

Little help please

Network all seems to run fine, connects to internet, shared drives, etc.  But when a certain  piece of software requires an update (AVG) we have issues on any machine connected to the network.

If you enter our DNS info manually, it updates and works fine.  But i cant seem to get the DNS to be auto detected, it picks up Google and something else, which dont seem to work.  We can get around with machines that stay on site but not much use for visiting equipment or those that work in several places

I can ping either dns address that we need to use on our IP's 192.168.250.250 (server) or 192.168.250.1 (Router)

I'm assuming its something in the configuration of the DNS Server thats causing the issue as nothing connects to the correct one.

Any advise would be great, thought it was all working and i'll be the first to admit, its bit of a learning curve. Hoping its something simple i've missed

Many thanks

  • Please run;

    • Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
    • repadmin /showrepl >C:\repl.txt
    • ipconfig /all > C:\dc1.txt
    • ipconfig /all > C:\dc2.txt
    • (etc. as other DC's exist)
    • ipconfig /all > C:\problemworkstation.txt

      then put unzipped text files up on OneDrive and share a link.

     

     

     

  • Pretty vague but assuming a domain environment then I'd check the domain controller and problem member both have the static ip address of DC listed for DNS and no others such as router or public DNS

      Thanks Dave.. Apols for the vague, this ones a carry on from someone elses job!! And to be honest, not at all sure as to how to deal with, hence why i'm on here

       

      Your correct, Domain Controller with the DNS.  I've now got the Server itself seeing the correct DNS (which it wasn't before), just not the clients now.  If i enter the IP manually, their fine. Leave it on Obtain auto and the NSLOOKUP comes back with DNS timed out and picks up google

       

      Its bound to be a server config somewhere i assume


      Any pointers, fire away.  Going round in circles at the mo!!
