Trying to Checkout No luck

I', using both Tortoise & WinCVS on this machine without any problem. When I try to checkout using the cvs dreamweaver extension I get

cvs checkout: Unknown method (`sspi') in CVSROOT.
cvs [checkout aborted]: Bad CVSROOT: `:sspi:kmccarty@192.168.1.107:\cvsrepo\srcmaster'.

We use sspi to authenticate. Any suggestions. No problems with Tortoise or WinCVS. I am using the lite version before purchasing to see if it will work as easy as totroise.We

Hi.
Please tell me your cvsnt version.
You can do this by opening the command-line window (start->run...->(enter "command")) and entering this command "cvs -v".
You should see like this:
"Concurrent Versions System (CVSNT) 2.0.51d (client/server)"

Paul.

I think you don't have CVSNT installed, you are working with WinCVS? Please try to do what my colleague Paul Nasca asked for.
