Novell GroupWise 8 Support Pack 2
Webaccess Application installation does not allow one to change the path to the webserver's root directory, if the webserver selected is Microsoft Internet Information Server (IIS) for Windows. If c:\inetpub\wwwroot does not exist, the installation will not complete.
Even though the default path to the webserver's root directory may be d:\inetpub\wwwroot, Webaccess does not write to the directory. For a temporary workaround, create a c:\inetpub\wwwroot directory, let the installation complete, then remove the temporary c:\inetpub\wwwroot directory, as it is empty.
