Error 1327 - Windows Installer

I repeatedly get "errror 1327" whenever attempting to install software or an
update to any existing software on one particular Windows Vista computer.
After diagnostic efrots, it seems that any program that uses the Windows
Installer suffers this fate.

The computer runs Vista Business which is a member of a Small Business
Server 2003 domain. The user logged-in at the time has full administrative
permissions on the local machine but consistently gets the same error any
time Windows Installer tries to do its thing. Like all other users on the
network (including other Vista machines configured in like manner). Like all
other users, she has drive H:\ mapped to her "Home" directory on the server.
She can access all files there and all other functions work as they should.
The 1327 error is accompanied by the text "Invalid Drive H:\". Her CD is
drive E: and no other network drive/share has ever been mapped to H:. I can
disconnect that drive mapping and still get the error. I checked the local
machine/software regsitry which has lots of references to H:\, but they all
seem to point to the correct location.

I have a cheesy workaround which is to logout and login as the administrator
on the local machine. Installations and updates proceed as they should, but
this is not a viable long-term solution. I've only experienced this on Vista
Business computers (I've encountered in on 2 or 3 others), but not all as
several others in the same environments work without a hitch.

Any ideas? Technet searches in various categories have come up with no
useful leads.

Help!

I would look over the Installer list for Clean Up. Something may be hanging
up. Look in the event viewer for clues.
