I just encountered the strangest problem I've seen yet with WSS.
I have a single user who has contributer rights to a site through
membership with an Active Directory Group called "Corporate
Engineering." All users of this group other than this particular user
can use the site fine and without issue.
However, when this particular user clicks on the name of the document
to open it, either in the web part or the document library itself, his
navigation results in a blank IE window with the "image not found" icon
in the top left corner. (The white square with the red x in it). The
only way the user can see the document is by going to "edit properties"
and clicking the "Open in Microsoft Excel" button. This would be an
acceptable workaround if it weren't for the PDF's, CAD drawings and
other non-office documents that he needs access to.
I'm having him try to log on to another machine to see if it is account
or machine related now. I will post the results when he completes this
request.
