IIS 4 SMTP service conflicts with www service

[Terry Truebenbach]

Has anyone ever seen where once the SMTP service from option pack 4 is added the www sites stop responding. i have a website that i am trying to migrate off of an old server and requires the smtp service to run on the server. on the new server the general website works fine until i add the smtp serice. After that the site just says found and waiting for reply. no errors generated.

NT 4 Server
Option Pack 4.0
SP3
Most current Front Page Server Extensions

have uninstalled multiple times with the same result...SMTP kills it. Anyone have any ideas?

Thanks for your help.
