We have recently set up a test domain controller to examine settings before pushing them to production at work.

Upon setting up this domain a simple error was made in the DNS settings. We forgot the subdomain.

testdomain.com rather than site1.testdomain.com.

We found a way to change a majority of the references, but Group Policy objects are not being applied correctly.

When running RSOP.msc. we get an error: RSoP data is invalid Invalid namespace

Did a bit of digging and it seems when we create a group policy, and click edit, the name does not reflect the servers FQDN.

dc01.testdomain.com rather than dc01.site1.testdomain.com.

How can we change this name space? or will we be forced to reset and re-run dcpromo.exe and ensure correct settings this time?

I have found my problem.

We renamed our domain using rendom.exe, which changed settings in the forest. And then removed to testdomain.com zone in the DNS settings.

However! We failed to change the domain on the domain controllers DNS suffix through the system properties (System Properties > Advanced System Settings > Computer Name > "To rename this computer..." > "More..." > Change DNS there)

It's funny, here, how you seem to find the answer to your question right after you ask it.
