Cause

The backslash "\" used for the username is not recognized, and will corrupt the authentication request from the webservice generator.

Resolution

To login using the Webservice Generator, you will need to specify the username without the "domain\" in the username: field. If the server is a domain member server, the authentication request is passed to the server and will continue with the wizard.

If this server is not a domain member server and/or does not have a trust relationship to the domain that contains your user account, you will need to modify the IIS Virtual directory or the webservice to allow authentication:

Right click and choose properties of the .asmx page that you are using for the Webservice Generator
Choose the Directory Security tab
Click Edit to modify the Authentication and Access Control
Choose the Basic Authentication checkbox and specify the users Domain and Realm
Restart the Webservice Generator and perform the authentication attempt again
