We have gemini installed at gemini.ourserver.com, and can happily use the web-application, but would like to try out the Desktop client. The web application uses Windows Authentication successfully, and users are logged in immediately upon browsing to the URL

When attempting to create a connection through the desktop client, I enable Windows Authentication and give the Gemini URL as http://gemini.ourserver.com, but am told that I am using an invalid Username or Password. The username has been automatically populated correctly, the password field is disabled which seems correct.

Can you offer any suggestions as to where I may be going wrong?

Thanks very much in advance
