The install instructions from Exchange ESM setup for a Win2K machine say to install IIS (done) and the Server 2003 AdminPak.msi. When I try to install AdminPak.msi (from Servr 2003 CD, which seems to be SP1) and from a download from MS, I get a message saying that is can be installed only on XP and Server 2003 machines. What gives? Can I install the Exchange ESM on a Win2K machine? If so, how to get around this hurdle?
