When I run the command

dfsdiag /testdfsintegrity /dfsroot:\domain\dfs full

I get the following error

Checking the registry of the namespace servers... Error: The system cannot find the file specified. Warning: Unable to verify the registry of the following namespace server: DC1

I have been trying to look what this does but can find anything on it.

Are you running this command with an account that has permission to access the registry on DC1? Does DC1 have a firewall that is blocking the command from running? – smassey Dec 2 '11 at 16:20
I am running the command as domain admin, I have also tried running the command on DC1 and I get the same error. – OptimAdam Dec 5 '11 at 8:44
