We are running into a problem with a remote location that we are joining to a domain that is connected via a Sonicwall VPN. We have another site connected that does not have this issue. When adding to the domain we noticed that it took a very long time and logging in also takes a long time. It seems as though computer GPO is applying fine but user gpo is not. DNS is configured correctly but when running rsop we get 'Invalid Namespace' and when running GPResult we get user does not have RSOP data (this is for any user). When trying to browse to the \\domainname.local we get a username/password prompt. This is happening for all workstations at this site, yet the other site yields perfect RSOP and Gpresult.
These computers were previously part of another domain. Any help would be greatly appreciated. Thanks.
