 Try openeing 5901 as well.

A VNC Server on a Windows PC will listen on port 5900, while the first
VNC instance on a Linux server will listen on port 5901, the second on
port 5902, etc. 

You can check with nmap what ports the drac listens to as well.

Command: 	nmap <RAC-IP-Add>  

Should give you something like:

Starting nmap 3.70 ( ) at 2006-04-04 11:44
Interesting ports on IP-Addr:
(The 1655 ports scanned but not shown below are in state: closed)
38/tcp   filtered rap
80/tcp   open     http
443/tcp  open     https
5900/tcp open     vnc
5901/tcp open     vnc-1
