I have reinstalled the ZCM server with 10.1.3 updates in Win2003 64 bit. Everythings seems fine after installation. Due to some reason, I cleared the proxy setting in ZCM after verified the license of patch management. However , on the next day, ZCM cannot connect to Internet even I had completed the http proxy setting on Patch management services and Infrastructure Management. I am sure that the proxy server and username and password is correct that is as same as the IE setting and IE's Interenet connection is OK. Does someone make some suggestion to me.
