Recently I moved my domain to new host company and I was able to access it in a couple hours after DNS get updated. But when I tried to access domain control panel(Cpanel) I got error message. The following error was encountered:
Connection Failed The system returned:
(113) No route to host The remote host or network may be down. Please try the request again.
Fist I thought well it's probably some kind of caching problem on internet so I just need to wait 24 hour before it get updated everywhere. Well on a next day I tried again the same result. I start doing some investigation and apparently IE 6 sp1 for Win XP has some kind of bug related to Basic authentication problem with Squiq/proxy caching server. I was able to access Cpanel from Opera. So far I wasn't able to find fix for IE6. Thought win 2000 Pro doesn't have this problem.
You might contact your hosting company about the IE issue. We recently had to move a site to a more secure server and the wrong CA bundle got applied to the SSL certificate and IE would not display an encrypted page though FF would handle it fine.
