First, thanks very much for Charles's reply. Our IP is 202.120.34.x and our campus network is not multicast enabled (maybe we can evaluate AG by bridge).
Our situations is (Windows XP+AGTK 2.1.2):
(1)We can enter a local venue, built  by ourself (using AG 2.1.2), e.g. https://202.120.34.x:8000/Venues/default.
(2)We can NOT enter the venue https://vv2.mcs.anl.gov:9000/Venues/default today . When we click the "go" button of AG Client GUI, it hangs.
(3)We can visit http://www.mcs.anl.gov, then we think that our DNS works well.
(4)We entered the venue https://vv2.mcs.anl.gov:9000/Venues/default one week ago successfully, but it doesn't work today,:(  Does the venue server shut down?

Any suggestions are welcome and appreciated. Thanks in advance!

Best Regards,
Xie Bo
