Stew,
See if this MSKB article resolves the issue :
You receive error message 0x80070003 when you try to update Windows from
the Windows Update Web site
http://support.microsoft.com/?id=836949
If not, see this :
http://v5.windowsupdate.microsoft.co...cleid=11&ln=en
Also, from a post by Torgeir Bakken, MVP :
" If the directory "%ALLUSERSPROFILE%\Application Data\Microsoft\Network"
does not exist, you will get this error.
%ALLUSERSPROFILE% is normally "C:\Documents and Settings\All Users"
To verify existence/create this folder, you can do like this:
Press Start/Run, and fill in this:
"%ALLUSERSPROFILE%\Application Data\Microsoft"
Press OK, and the Microsoft folder will open.
If no Network folder is found there, create it (File\New --> Folder). "
