MSDN error on VS2003 while running as non-admin

I've recently dropped my main XP user down to the "average schmo" level like I should (and like I have in my primary development VirtualPC image.) When I tried to pull up the help on anything the installation wizard for VS2003 would pop up, eventually failing with this error:

Error 1606.Could not access network location wwwroot$: Unable to get security info for this object.

In case anyone else has this problem, here's how you fix it (verbatim from Felix Wang):

Log on with the Admin user.

Rename the following file:

C:\Program Files\Common Files\Microsoft Shared\Office10\mso.dll

Launch VS.Net and let the reparation to finish.

Launch MSDN.

Close VS.Net and MSDN.

Search for the file named "CookDoc.dll". By default, it should be in
"C:\Program Files\Common Files\Microsoft Shared\MSDN".

Let's register the file by the following command:

RegSvr32 "C:\Program Files\Common Files\Microsoft Shared\MSDN\CookDoc.dll"

Logon with the original user.

Scooped from usenet on microsoft.public.vsnet.setup in this thread. In case this link doesn't work the original post is titled "VS.NET/MSDN Annoyance" on Mar 9, 2004.
