Hi,
When connecting your server remotely you should use a X-emulator application for it. Reflection X, Hummingbird Exceed, KEA X, are possebilities for this.
It's just a matter of clinet cnfig to connect then (of course X-Server need to be started, but that most of all is done already.
For hardware connection, you should connect a graphical temrinal to it
If you don't know how to do it, you should probably contact your PC/Server provider for technical assistance.
