After logging in, I click the "Manage Weblog" link. The following error is returned:
Can't call method "name" on an undefined value at C:\Inetpub\wwwroot\mt\lib/MT/App/CMS.pm line 200.

MT is running on IIS on Windows 2000 Server.

A Google search finds several static pages at various MT web sites with this exact same error.

What might be causing this error? Thanks.
