Having intermittent problems hitting your favorite UNC path over openvpn? Does your Domain Controller turn it’s back on you randomly over the tunnel asking for authentication as if it no longer knows who you are?
If you have been plagued by any of the above anomalies you are not alone! Unfortunately hair loss products, Viagra, those vitamins you bought from GNC, or any other magical elixir of some unknown origin will not help.
You may even find yourself going down the same foolhardy path as yours truly. Thinking that editing %SystemRoot%\System32\Drivers\etc\hosts with the FQDN and NetBIOS names of all your favorite hosts will suffice only to be greeted with the grotesqueness of an authentication prompt repeatedly prompting you for information it should already know until you become mad. Finding yourself breaking out those emergency cyanide pills and washing them down with a flask of hemlock.
Wait friend! No need for such drastic measures yet. Simply edit your servers config file to include the following:
push "dhcp-option DNS ip.of.dc"
Make sure your client config allows pushing by having the following cleverly named setting of:
Now once you’ve restarted your server and client you should see your DC IP set as the default name server when typing ‘nslookup’ at the command line.
Yes a simply fix but still worthy enough to stop any self mutilation.
