First of all, I know nothing about MS Exchange, so bare w/ me. We recently purchased a server with Win2k server. We want to install Exchange 2000. Do we need to install 5.5 first? I have tried to install 5.5 first but when installing 2000 as an upgrade, I encountered many errors. I then removed 5.5 and then tried to install 2k doing a typical install, there was an error stating that NNTP component of IIS is not installed.
