Log in without password

A school were i work has this server running without any password. I told them they have to get a password, but they refuses it, cause many teachers have to log on on that system and most of them would lost the password.
The only big security is that it is not connected to the internet and only available for the intern network.

Now i have to do some things on the server and most of the time i just use terminal Services Client to connect, but this time it is not working, cause he keeps asking me for a password while there is no password.

Is there any way that i could connect to this server without the password? Since i am not the system administrator, i cannot make new accounts for it.

Is there any other way to connect to the server? It is a windows 2000 server machine.

Thanks.
