When IIS service is installed on the Windows 2008 R2 server it only installed the default Role Services needed for it to function properly. But in order to run GroupWise WebAccess it need to have "ISAPI Extensions" and "ISAPI Filters" also installed along with the default IIS installation.

If above mentioned Role Services are not installed during IIS installation and GroupWise WebAccess Application is installed on top of it, follow the below mentioned steps to make sure that the GroupWise WebAccess is properly configured and running.
