It's a general rule that you can't have two services listening on the same IP address and port number. You could move one of the web servers to listen on port 8080 or some other port and leave the other on 80. The one listening on 80 could have a link pointing to the other one (ie. http://listserv.apa.org:8080) --- Inanimate objects rock with glee as they conspire to baffle me. - Ogden Nash William Brown Email/Internet Services Erie 1 BOCES (716)821-7285 Robert Caternor <[log in to unmask]> Sent by: LISTSERV give-and-take forum <[log in to unmask]> 06/23/2003 01:06 PM Please respond to LISTSERV give-and-take forum <[log in to unmask]> To [log in to unmask] cc Subject [LSTSRV-L] Listserv Maestro I am having a problem running Maestro. It appears the Tomcat web server and IIS will not running together. I have to install Maestro on the same server that Listserv is running on, which is a Win2k SP3 running IIS 5. The problem is that Tomcat will not run when IIS is turned on. I have added another IP address, which I was going to use specifically for Tomcat/Maestro while the other IIS uses the other IP's. Is this possible. Any help is greatly appreciated. Robert Caternor
