We finally retired our old Internet proxy server (Not a SIP Proxy) and pushed scripts to all desktops to clear the proxy cache files and flush the DNS cache. We also blocked WPAD resolution to prevent the workstations from re-auto detecting and using the proxy. After doing this, we're seeing random users have issues using the Desktop client. They can log in, but it can take a very very long time (30+ minutes) before their workspaces start to load. We discovered that going into Control Panel ==> Internet Options and disabling proxy auto detect solves the issue. Is there some spot where the Desktop client has cached proxy settings that we need to clear? We don't want to leave this box unchecked, as some laptop users may go to a location that requires proxy before they can get to the Internet. Denny
