Please help

Does anybody know how to Access VNC server? I used to connect it without any
problems but right now there is an ISA Server 2000 installed in domain and I
can not connect it. I used to connect with
http://ip:5801 <http://ip:5801/> 
Right now I see the VNC authentication screen but when I input the password
I get "java.net.NoRouteToHostException: Operation timed out"
Anybody had this problem? Don't know how to configure ISA server about this
matter
 
I greatly appreciate any help
Thanks in advance
