I have windows vista ultimate sp1 installed, when i had xp it looked like yours, but i do not know in windows vista

I just  wanto to connect remotely from any computer on the internet, like my work computer, or college computer...

When i try to connect from my work computer i get the following error messages:
The client could not estabilish a connection to the remote compurter.
The most likely causes for this error are:
1) remote connection might not be enabled at the remote computer
2) The maximum number of connections was exceded at the remote computer
3) A network error occurred while estabilishing the connection
this message is appearing on my work computer, i work in a hotel, could the admins have changed this option? i checked the exception on windows firewall on my work computer and everything seems to be fine

i have forwarded the port 3389 on my router to my ip address 192.168.11.x ....my router is the buffalo WHR-G54S and i forwarded all the ports to mu ip address
