Environment: GW Messenger 1 sp1 on Netware 6.5

Everything was working fine until last server restart. Now the messenger
agent does not respond to browser requests for the default web download
page. All users which had previously downloaded the client can still
login and use the GW Messenger. The Messenger Agent Monitor web page is
still accessible. When I attempt to connect to the web site at port 8300
the C/S Requests rapidly cyles up but no page is displayed. It appears
to be stuck in a loop. I have checked and no other service is using port

Any suggestions?
