This behavior can occur because the Default Web Site in Internet Services Manager has been deleted and Exchange 2000 Setup cannot continue until you re-create the Default Web Site. Text similar to the following is logged in the Exchange 2000 Server Setup Progress.log:

The following path is being verified in the Progress.log and is located in the metabase:
IIS://ComputerName/W3SVC/1
Because the Web site does not exist, the path is not present and the installation does not respond.
