branch name change

[hamid]

How can one rename a branch.  We created a branch label and after some work
realized that the branch name is wrong.  Instead of recreating another
branch from a base line and try to figure out what needs to be added, I
would like to change the branch name.

We tried to use the following command;
cvs admin -nNEWNAME:OLDNAME and got the follwing message;

cvs aborted:usage is restricted to repository adminitrators.

We are using CVSNT.

Thanks
