[cvsnt] cvs [server aborted]: can't create temporary directory

[paul]

hello,

I can't get cvsnt to work properly due to this error: cvs [server
aborted]: can't create temporary directory.

C:\>cvs -t checkout test
  -> Tracelevel set to 1.  PID is 1712
  -> Session ID is 6b0426ab3e22c54
  -> main loop with CVSROOT=:pserver:MYDOMAIN\paul at my.cvs.server:/cvsrep

cvs [server aborted]: can't create temporary directory C:\TEST/cvs-serv1780: Per
mission denied

Under the Advanced tab, I have set:

Run As User -> MYDOMAIN\cvs-repository 
Default Domain -> MYDOMAIN
Temporary Directory -> C:\Test

If I login as cvs-repository I can create files & directories in C:\Test

If I set Run As User to (client user) I don't get this error.

I have even added SYSTEM to have full access to C:\Test but it makes
no difference.

Any help would be appreciated,

Regards,

Paul
