For Windows 95 and 98 you need to specify a username and password defined for that machine.
For NT it is slightly more complex as NT machines are usually part of an NT domain. You may specify either a local username and password on that NT server or a NT domain username/password. The OOB Server, passes either NULL or the specified domain name to the NT function LogonUser(). You can specify a domain in the LogonUser attribute like
If "Domain/" is not specified, the OOB Server passes NULL to LogonUser() which means the local account database is searched first and then trusted domains.
If Domain is "." (e.g. ./username), then the search is restricted to the local account database on the NT Server.
