how to able a disabled account

[3c]

Hi,

I just installed CVSNT 2.5.03 on my WinXP-SP2 PC and have experienced an 
error "usr account disabled"

It happens when I attempt to log in
The error message is:
 C:\Documents and Settings\Baz\Desktop>cvs login
Logging in to :pserver:address@hidden:2401:/ROOT
CVS Password:
Fatal error, aborting.
cvs [login aborted]: cvsadmin: user account disabled

Prior I set cvsadmin account as:
   C:\cvsrepos>cvs passwd -r cvsadmin -a testuser
Adding user address@hidden
New Password:
Verify Password:

testuser is the current login account on Windows OS.

I tried to figure out what wrong was, but I could not fix the problem.

I've used CVS for many many years at work, but this is my first time to 
install CVS by myself. I appriciate any help.

Thank you in advance.
