Ultrasurf and Non-DHCP server

Hi, does anyone know of an easy method to get Ultrasurf running without DHCP enabled.
Ultrasurf 8.2 was working for me perfectly until yesterday, I suspect the culprit is that the network admin turned off DHCP yesterday.
I can still connect to Ultrasurf at home, so it might not be a national thing.
I tried both Ultrasurf and Gpass, both have trouble connecting to servers.
After some research on Google, it appears that it is possible to get Ultrasurf running without DHCP enabled, the problem is I just don't know how.
I hope it isn't too complicated, besides I don't have admin privileges anyway.
It would be kind of dumb to go up to the admin and say something like hey turn on DHCP for me so I can access news sites and forums the PRC government considers bad for the people (even for foreigners working in China).
The system is running Windows 2000.
 
Apparently there seems to be a causation.
I came home and did a test. I turned off DHCP on my router at home and Ultrasurf and the like stopped working altogether.
I turn DHCP back on and voila!
So I guess it does need DHCP.
Now only if I can just figure out how to solve this problem...
Thanks.

I was also kind of wondering whether it would work if I just plug in a router by myself and enable DHCP on that? Would that work?
I mean just plug in another router between my PC and the office LAN outlet.

I can't begin to tell you how ironically correct your logic is, albeit extremely skewed.

If you unplug your PC and ultrasurf stops working, then plug it back in and it starts again, you could say the same thing about your power cable, according to the logic you have exercised. While not incorrect, this is flawed troubleshooting at its finest.

DHCP is only the protocol that automatically assigns IP addresses in the network your PC resides. It has nothing to do with blocking an application. If you think your network admin has turned off DHCP to prevent you from using an application, you're wrong. It's worse, he doesn't want you to have automated access to any IP layer whatsoever if that's the case. Be the better person and ask the admin rather than trying to troubleshoot the network; sorry, but you're just not qualified to make the correct diagnosis.
 
Umm...maybe I should clarify a few things...
The app itself is not blocked, I mean the application still runs.
The problem is that it reports it can't connect to any of its servers, thus it is useless.
I did some browsing and it seems that nearly all of these anti-censorship tools rely on dynamic IPs and that has to work with DHCP enabled.

To answer the second part, I guess you are right, but I don't think I have enough brownie points with the net admin and some times it could take up weeks for them to respond to any request.

 
Oh yeah, and did I mention that technically that these Taiwanese and American news sites and forums I usually visit are considered "illegal" in China, thus they are filtered by the Great Firewall of China?
Heck, I can't even look up Wikipedia and God knows how many links are filtered by the search engines including Google.

From our point of view, it is ridiculous. The locals might think very differently.

Well, at this point it's more of a political discussion since I'm not about to give you the information necessary to get around that censorship system (thus the noose to hang yourself by). Buy the admin lunch and see how far that gets you. 😉
