When you are using a NT-based OS or Win2000 Server...

1. Run "dcomcnfg.exe" from the commandline.
2. Open the tab "applications"
3. Search for "klav" and double click for properties.
4. Open the tab "General"
5. For Authentification-Level choose "none"
6. Click "Apply" and "OK"
7. Reboot the server.
