Server installation problems...
Today I've seen a very strange problem.
I've finished the development of a couple of Web Services and I needed to put them in production.
I've received the Windows 2000 Server already locked down, with a lot of tweaks, permissions changed, IIS Lockdown, URLScan, registry tweaks, etc...
I've installed the .NET Framework after the locking (it was the procedure that they used for every other environment), but this time there was no way to have ASPX and ASMX pages served.
Everytime I try to read ASPX or ASMX pages, I receive "You are not authorized to view this page" without any information in Event Log, IIS Log and URLScan.log.
Also nonexisting pages return the same "not authorized" error.
I've tried some knowledge base articles, I've restored the permissions on the directories, removed URLScan and IISLockDown, but nothing happened.
Tomorrow I'll receive a new server not already locked down, I will install the .NET Framework, and then we will try to lock down the system.
Perhaps we will find what is breaking the connection between IIS and ASP.NET...
The moral of the story is: "Do your work BEFORE others can break it!!!!"
UPDATE: We've reinstalled .NET on a fresh installation of Windows 2000 Server and applied exactly the same tweaks and locks, and... EVERYTHING WORKS :-)
