I am stumped.
I have a series of CUCM clusters in my lab. Today, for some unknown reason, I can no longer access one of the Pubs from IE with a "This page can't be displayed" error. I can open its Sub in IE, and I can open other Pubs and Subs in IE. For the Pub that won't open in IE, I can open it in IE in Firefox and in Chrome.
To make life more interesting...I'm observing this behavior on three different PCs, so I don't think it is the browser.
Even so, I checked to make sure I have no entries for any of my lab systems in "Restricted Sites". I have cleared the cache (and history, etc.). I have cleared the SSL cache. I even went into my registry and did a search on both the IP address and the hostname of the server. No joy.
Any suggestions would be welcome.
