Hi,
I followed all steps regarding setting up a custom AD in azure
I followed all steps and all worked nice, until about a week ago. (I assume the machine got rebooted or reallocated to some other area in the Data center, which might be causing issues)
I set up my virtual private network to be in the 10.0.0.x range and my AD server + DNS is 10.0.0.5
DNS is configured in the virtual private network settings and all my domain joined clients recieve this as the dns server to go to.
All of a sudden my client VM's that have joined the domain start to show intermittent problems with accessing internet resources.
this means that when I type an andress in the browser I sometimes get the IE dialog that I don't have a connection and sometimes it jst resolves fine.
I tried to look with nslookup and there I found that I get most of the time the response back that the request timed out
So I looked at the DNS server, shich is the same as my domain controller and there I tried the same. Exact same issue.
response is like this:
C:\Users\marcelv>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: 10.0.0.5
> google.com
Server: UnKnown
Address: 10.0.0.5
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out

So then I look at the DNS configuration and I see that the forwarder set for my DNS server is the same as the DHCP server that provides the ip adress. Now this server can not be resolved on the properties tab as well.
the probem is, that I am rather clueless what to do here?
I Can't find a way to provide a new forwarder name, since I think this is the culprit of my problem, if the forwarder is not available or not responding or responding occasionaly, then that migth be the issue. But I can't seem to find a list or set of ip adresses I could give there to set a forwarder that works.
Perhaps I am looking in a complete wrong area, and would love to get some help getting this resolved, since a development network without reliable internet access is rather useless.
Let me know what diagnostics I can run to provide additional info and I happily provide it.
Thanks a lot in advance,
Marcel
