LiveUpdate Administrator 2.3.0 - Known issues:
.....
•In Source Server and Distribution center configurations, application is supporting proxies with Basic and NTLM authentication. For configuring NTLM proxies in LiveUpdate Administrator, the user needs to specify Domain to which proxy is connected. There is no separate input field for entering domain name. User should enter proxy user name as "<domain_name>\<user_name>", which is domain_name followed by "\" and then user name.
Hope this helps! For the benefit of future admins with the same question, please do not forget to mark this thread "solved" (it is still currently "needs solution.")
