Web Service and Linux not working

I am trying to run a web service on two different Domino servers. Both are running SUSE Linux, one Professional and one SLES

I get the following message on the SLES box

HTTP Web Server: Lotus Notes Exception - The Web Service could not be run.

Any idea why I get this message? No web service wants to run on this box.

Make sure the Linux web service aren’t running (ie. apache2, ldap, & postfix).
