Hi

So here's my situation. I've got IIS v5.0.2195 running on the same box
as my SQL Server which hosts ASP and ASP.NET applications

For authentication, i have 'allow anonymous' unchecked and 'Integrated
Windows Authentication' checked. I'm also placing users into a domain
group which subsequently gives them access to my ASP or ASP.NET
application

This all works fine to a point, but here comes the problem. Every now
and again it seems like IIS is losing the credentials of the user that
is logging in and ends up displaying the lovely (Login failed for user
'NT AUTHORITY\ANONYMOUS LOGON') message.

When you refresh the page everything is back to normal until an hour
or two later the same happens again.

Has anyone else seen this temporary loss of credentials before and if
you have, please oh please let me know if you managed to fix it?

Yours Despairingly
Muirboy
