Novell Client Login – Win Security Error

I have just setup a new workstation for my school network. We are running a Novell 6 network with the latest clients installed on the workstations. This workstation is loaded with WinXP and the Novell Client 4.83SP2. When I log into the computer,I immediately get the following error:

Windows Security Message
Unexpected login error. Status: 1327.

When I click on the OK button, it then asks me for the Windows username and password, which is typical for WinXP. Upon entering that information, the Novell login script seems to perform fine, and my drives are mapped properly. Does anyone out there know what this message is, what is causing it, and how can I fix it? Thanks.
