just found something very strange with IIS5.0 it doesnt check to see if ports are bound. I have a apache running on 10.100.2.7 (listening to port 80, 443) and 10 other IIS's on 10.100.2.10-10.100.2.20 also listening to port 80 If I try this they scream, 'address already in use' -- although ISM doesnt have any IIS sites bound 10.100.2.7 or unassigned. you can test this. get something besides IIS running on port 80 ;) Now. for them *not to* scream you need to bind a second ip address to each website lets say 10.100.2.10 port 80 as well as 10.100.2.7 port 81, then this site wont complain about 'address already in use'. ready? no goto 10.100.2.11 site, add a second port, 10.100.2.7 port 81. no complaints. both are running listening to teh same port? w/o complaining about 'address already in use' ;) lovely microsoft ~runyaga
