We have OWA published with ISA 2006. We change background color and gifs of OWA logon page. All works fine, shows correctly all gifs, lgntop, lgnbottom, lgnright and lgnleft, and backgrownd color.
But I experimented a "poltergeist". In my enterprise network works fine, in mobile network works fine, in my girlfriend's house networks works fine, but in my home does not shows lgntop.gif. I dont know whats happenned...I try it with my 2 laptops and my Android phone via browser and not shows lgntop.gif. With my android phone switch WiFi to 3G connection and works fine with 3G.
This behaviour make me crazy and I don know whats happened...
I try to open webmail with IExplorer and Google Chrome, and the behaviour its the same, does not load lgntop.gif. In Chrome go to right button and click in "inspect element" (last option, I dont know how to say in english, sorry)...and go to console and show me this:
