HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "D:\Novell\GroupWise\connector\bin\isapi_redirect. dll" failed

Hi getting the above error when I try to get to a website on my webserver in IIS 7 after the install of the Web Access application on a 2008 server. iF i try from another pc I get a generic 500 message. A little background I had a site running on the server that has 5 url's. Ran fine until I tried to install webaccess. All other agents are on an OES box and running fine. The first time I tried to install the application I set d:\bico as my web root since that is where my sites are. Didn't work so I removed the directory structure and stopped Tomcat 5.5. Then ran the install again pointing to default c:\inetpub\wwwroot. It created a directory under inetpub and I still get the same error pointing to drive d. So how do I completely remove evrything and then get this working. Urgent issue since now even if I remove all directories from webaccess I can't get my sites to come up. Please help.
