In what has to be one of the most bizarre regular expressions I've
ever written...try adding the following to your config.php:

$UrlExcludeCharsWin = str_replace('\\\\', '', $UrlExcludeChars);
Markup('\\\\server\file', '<wikilink',
  "/\\\\\\\\\\w+\\\\[^\\s$UrlExcludeCharsWin]*[^\\s.,?!$UrlExcludeCharsWin]/e",
  "Keep(MakeLink(\$pagename, 'file:///'.str_replace('\\\\\\','%5c','$0'), 
    '$0'), 'L')");

(Yes, that's right, there are *ten* backslashes at the beginning of that
string.  Isn't Windows fun? :-)

This converts urls of the form "\\server\file" into file:/// links.
So far it only works with "bare" \\server\file links -- i.e., it
doesn't understand [[\\server\file | link text]] (let me know if you
need this -- I'm sure it'll somehow be even more bizarre :-).

I have this particular modification available for demonstration
at http://www.pmwiki.org/wiki/Test/WindowsFileUrls .

I tested it under both IE 6 and Firefox 1.0 and it appears to work okay.
Under Firefox I had to set the server.checkloaduri property to get it
to accept file: links (as discussed previously).  Surprisingly, I didn't
appear to have to do anything to get IE 6 to accept the file: links to
another server, even though it wouldn't let me access files on the local
server.  Sounds like another IE security hole.  :-)
