Strange Group Policy Results

Hello

I have a logon script (vbs) assigned through group policy to map a
user's "home" drive, but instead of that happening IE opens after
logon and attempts to connect to http://home drive.vbs (home drive.vbs
being the name of the script.)

The vbscript works as written outside of group policy, I have a test
user account in a test ou (the policy is applied at the OU level) and
the user has read and apply on the policy.  No other GPO's are
configured anywhere in the domain.

What am I missing?

Thanks
