You don't.
You set your UT network to use OPENDNS and enjoy this being blocked
and much more, for no more money out of pocket!

You can use Anti-UltraSurf 1.0.1.32 -Beta , just google for this and install it on the PC on which you don't want users to run Ultrasurf.
This tool disables UltraSurf.
After you install this tool, ultrasurf won't be able to loadpages.
Let me know if this helped.
Block all 443 in firewall and add rules to pass what you need...
It is better to have a protocol signature to block ultrasurf.
But I guess there is no protocol signature for ultrasurf at this time I think.

signature is good idea actually...
You can't block Ultrasurf using the DNS filtering of Opendns, it is impossible to block because it uses encrypted connections.
Tip: I used the free astaro as my internal firewall just to block this ultrasurf and other encrypted proxies...
OpenDNS can and does block this. OpenDNS works by denying the DNS lookups required to resolve the IPs. However, it's far from perfect and to be honest it isn't realistic to expect to control encrypted proxies. You will get one blocked and 5 more will bypass your block.
