User Control - failed to map the path

[Craig Santoli]

Hello,
I have an ASP.Net 1.1 web page running on an IIS6.0/Windows 2003 Server. In
the page I have a user control that is dynamically created using
LoadControl. The page works fine at first (after being installed on the
server), but after a while (say 30 minutes), the page returns the error
below when loading...

Any help is greatly appreciated. Thanks!
