In our local subnetwork we have a domain server. It's a Windows Server 2008 R2.
It was configured by following this guide I think.
My main domain is wm.local
. My server is domainserver.wm.local
. My devices are dev1.wm.local
, dev2.wm.local
etc.
It works fine most of the time, but sometimes a client cannot resolve an other device's domain name. For example I can ping the IP address of an other client, but pinging the FQDN results in: `Ping request could not find host dev2.wm.local. Please check the name and try again.'
when I whip up nslookup
, I can actually look up dev2.wm.local
without any problems:
> set q=a
> dev2.wm.local
Server: domainserver.wm.local
Address: 192.168.1.203
Name: dev2.wm.local
Address: 192.168.1.102
So the given domain can be resolved.
Restarting my network adapter solves the problem temporarily.
But for example ipconfig /flushdns
does not solve the problem, the host is still unreachable for any request (ping, http, and remote desktop are the ways I'm trying).
Since this happens on more than one clients, I'm guessing that there is something misconfigured on the server.
What would be the best way to find the source of the problem?
Since I'm a programmer and not a system administrator I'm trying to search for a solution on the internet, but I have no first hand experience on how to configure a dns server.
Here is the output for ipconfig /all
