Ubuntu Issue

[whiz]

In a nutshell this is my problem. I have a stand alone server that i want Ubuntu to run and I want to VNC into this server using my gaming WinXP machine. Now... When I have a keyboard & mouse plugged in I can use Real VNC and remotely connect just fine. When I restart the machine and unplug the mouse monitor and keyboard. It won't let me VNC into the Server. I think I lack the knowledge of linux command line so any help on a fix for this would be appreciated.
