Can't Login to webapp, view tif's files when not logged in Server

[JeffP->]

After re-booting the Win2K server, our ability to login to our web app is
limited to loading the login page, but we get a typical invalid object,
(userLoginSecurity)

Then I login to the server, we can now get to the main menu, but either we
get another error, because it can't load the menu, which is user specific
from an SQL table via sProc, table(0) error.

To cure, I login to the web app at the server console and now we can login
from any workstation, but our image files, scanned tif files are not viewable.

A few more clicks in IIS to stop & restart, opening the web app again at
ther server and viola it's all working.

FYI: I just today loaded my WebApp.Dev version to debug, that requires
another post to get working.....

TIA
