Windows Explorer Crashing when opening Network Share

Hi

I have this problem where Windows Explorer crashes every time I attempt to
access one particular folder on our network. If I look at the Event Viewer I
get the following message:

===========================================

==========================================

The problem also occurs when I try to view a MOSS Document Library in
Windows Explorer mode. Seems to be caused by shlwapi.dll which contains
functions related to UNC and URL paths.

Have reinstalled XP SP3 and searched for any registry errors but not had any
luck. Would be grateful for any advice received.

Many thanks,

Dougy
