Install Issue - "IIS is either not installed or not configured for a server component inst

I'm getting this error:
"IIS is either not installed or not configured for a server component
installation"
when attempting to install Reporting Services on W2K Server SP4
Configuration details:
Windows Server 2000 5.00.2195 SP4
IIS is installed (Control Panel Add/Remove components confirms this)
Default web site is present
Default server IWAM account is active
Default web site IP is mapped to (All Unassigned)
The web server is functional, as it is hosting another .Net web application
already.
I can't seem to find any useful info on this error on the web.
Any suggestions appreciatedFYI in case anyone else encounters this problem:
Something in the configuration of the existing default web site (don't know
specifically what) was preventing setup from recognizing the IIS install.
To work around this problem I disabled the existing default web site, and
created a new one with all the defaults set.
