In JRE 1.4.2, we are supporting NTLM connection, the user will see a pop up dialog box to enter user name and password to authenticate. Currently, there are only two fields in authentication dialog box, "Username" and "Password", it will only work if the user is trying to access a machine in the same domain. If user want to access to different domain, he/she has to provide domain name.

Here are the workaround:

Username: domain\username
Password: password

So the user has to provide "domain\username" in Username textfield in authentication dialog box to access machine in different domain. We have to specify this in user doc.
