I am having troubles with some Group Policy’s with my domin and VPN. What I am working is Microsoft SUS server. What it does is goes to Microsoft and downloads updates and then I approve them for the clients to download from my server and install them. I am still in testing but close to the end the problem comes in with the VPN. There is a policy that comes with this through a template where you can specify what time the client looks for updates and what server and so on and so forth. I have no problem with clients updating to the new group policy at “home office” but when I go across the VPN I have problems. I am almost certain that it is my Firwall VPN device. I have also looked at the event viewer and I get this error:
Source Userenv
Catergory None
Event ID 1000
Type Error
User NT Authuority\System
Description: Windows cannot obtain the domain controller name for your computer network. Return value (59)
I know what the error means, “An unexpected netowrk problem has occured” but that really helps a lot. I know my physical network is fine. I know my DNS is working fine, as well as my WINS. I believe that this error has something to do with the computer on the remote end of the VPN trying to update its group policies. I did some reading and found out that there is another place on the client where you can look at the log and see where it may be having problems. I looked there an this is what I saw:
Userenv (b.268) ProcessGPOs: DSGetDcName failed with 59.
