Interesting problems with .Net Server - it doesn't support Exchange 2000.

Apparently, Exchange 2000 SP3 has components for support of .Net Server, but I am not sure what the install order should be to get it working correctly.

From Spencer F. Katt:
some admins have issues with Service Pack 3 for Windows 2000. They're finding that not all the security patches that were supposed to be in SP 3 are there and that when they try to download the missing ones, Windows won't let them. Apparently, it won't let you go to patches that are pre-SP 3. A friend of the Furball said some people have also found that machines with SP 3 installed aren't recognizing certain characters in the password field during log-in.
