I'm having two problems with new Vista PC that the place I bought it from
can't help me with.
1. Can only map a network drive if I don't have to login, & if it does map,
explorer crashes when I try to disconnect it.
2. Get WIA errors on system startup & trying to use scanner or Photoshop.

I ran sfc /scannow as per <http://support.microsoft.com/kb/929833> and sure
enough, it came up with several errors that it was unable to fix.
These included netplwiz.dll.mui and wiaservc.dll.

The article says to "replace the file with a known good copy of the file"
but I don't know where to find "good" copies of these files.
I don't see them on the vista install disk and I can't find any reference to
them in Microsoft support to download.

Does anyone know where I can download "good" copies? I'm using Vista SP1.

Thanks,
