The following error occurred validating the name workgroup
Tried to join my girlfriends comp to the domain but no joy.
I have A records and PTR records for all the comps on the DNS server. In MY NETWORK PLACES on the client the domain shows up, as well as the workgroup the client is currently a part of... Thanks Freakout when you try to log on does the domain name show up under options?
If so, verify within DHCP that your Dynamic Updates are on..make sure when you are joining the workstation to the domain that you are listing the domain name as you entered it (domain.com, domain.local, or whatever it was).
Make sure you do not have a computer account already created in ADU&C for the workstation (if so, delete it).
Once the recommended configuration is performed, you may join the computer to the "%1" domain. Please contact your domain administrator and indicate that the computer failed to update the dns Host Name and/or service Principal Name (SPN) attribute in its Active Directory computer account. Please do one of the following: -- Configure the computer's primary DNS suffix to match the Active Directory domain DNS name or any other allowed primary DNS suffix.
-- Contact your domain administrator to allow computers that are members of the "%2" domain to have "%3" as their primary DNS suffix.
Remember any slight change in a DC's DNS can really throw spanners in the works. Check out Jack in the Box's post regarding this and other things DNS here.
Specifically, check out the pictures of the DNS console at the lower portion of the thread.
Specify a smaller page file size or free some disk space. DNS names may contain letters (a-z, A-Z), numbers (0-9), and hyphens, but no spaces. Standard characters include letters (A-Z, a-z), digits (0-9), and hyphens (-).
Domain controllers cannot be moved from one domain to another, they must first be demoted.
Renaming this domain controller may cause it to become temporarily unavailable to users and computers.
For the list of the allowed DNS suffixes contact your domain administrator.
-- Contact your domain administrator to allow computers that are members of the "%1" domain to have "%2" as their primary DNS suffix.
