How to do Remote Desktop connection over LAN

I want to connect my PC to some other PC remotely on network. can someone tell me stepwise how would i be able to do so?

Moved to right section.

It is easy.. You can use windows Remote Desktop Connection or You can use software like Ultra VNC.

Ricky!
I have enabled my server ( Windows 2003 with SQL 2005) -remote desktop and remote assistance
But not able to login. I could login remotely to another client in the network when I created another user with admin rights.
Should I do the same in the server too??
The reason I did not create another user is, like in win XP, if you create a new user then the "Administrator" goes off and is irretrievable. I don't want to mess up the login issues, since our ERP is linked to "Administrator" + sa
You got any ideas?
( FYI: I'm in Lagos, Nigeria)

Thanx for your time, Ricky.

Sorry for late reply..

You should be able to do remote login via User account which is available on server !
