Hi all,

This is the first time I've encountered this problem.

This moring I have installed .Net 2.0 framework and AJAX 1.0 onto our server
which already had .Net 1.1 installed upon it.

After installing some security patches and rebooting everything was back up
and running.

I then tested my application and received the large red "Server Application
Unavailable" error message, I've seen this before and often hitting F5
clears it - not today it would seem.

I checked the event viewer as it recommended and I have these errors one
after the other at the same time:

aspnet_wp.exe (PID: 2076) stopped unexpectedly.

So it looks like theres a permissions/security problem (middle error
above) - so does anyone have any ideas how to resolve this?  .Net 1.1
applications still seem to be working.

Thanks in advance for any help.

Regards

Rob
