Hello, I am on win 2k with IIS 5.0

I'd like to know how to install Imap without overriding any settings (I have pop 3 port 110 using mail01.domain.com)

When imap installs, do I just go into Internet Services Manager and type mail02.domain.com port 143?

What do I do to get it to work? I need a certain php based script to work, I have the imap.dll support with php, but it seems imap wasn't installed and the webhost will not help.

Any ideas? I am looking for what to physically do, especially after the file is installed, where to go. Anybody know?
