Hi, I have been beating my head against a wall for about two months with a particular Server 2008 R2 SP1 box on a domain. Fairly simple stuff. One day WSUS stops working and starts reporting errors, I tried everything and anything, but it just wont work again. So I gave up on WSUS for this machine and tried to install DHCP instead. But that wouldn't work either.. reporting some errors about unable to contact a domain controller, etc.. Finally I noticed in the Network and Sharing center, that it is saying my primary network adapter is in the PUBLIC location and unauthenticated. The network settings, DNS, GW, IP and subnet are all correct. I changed the location to Work (PRIVATE) but until I fiddled with the network cards a bit more, it did not go into DOMAIN location (though eventually it did). However after a reboot it defaults back to PRIVATE. I suspect that this is why DHCP and previously WSUS would not work on this machine (because it has problems talking to the DC). Note that I can ping both DC by name and FQDN. Can anyone please help to resolve this!!! I am at my wits end and about to just blow the damn server away and rebuild.

Hi, Thank you for the post. The domain network location type is detected when the local computer is a member of an Active Directory domain. You cannot manually assign domain network location type. http://technet.microsoft.com/en-us/library/cc753545(WS.10).aspx If your server cannot send DNS/LDAP queries to locate the domain, it will consider your server is not a member server which could change the network location type. So try steps below to check your server configuration: 1. Ensure the firewall rules for the Public and Private profiles had been set to allow all outbound traffic. 2. If step 1 does not work, try to open ADFS--restore default policy or turn off windows firewall in all profiles. http://technet.microsoft.com/en-us/library/cc766337%28WS.10%29.aspx 3. Moreover, close your antivirus software/clean boot your server to check the network location. http://support.microsoft.com/kb/929135 If there are more inquiries on this issue, please feel free to let us know.
