Nadya,

>The IE5 Error message 'Can not etablish connection with the server...', etc. comes each 5 min. today. What's wrong? And it works very very slow :(

I don't know about the 5 minutes thing, but since the UT came back up I have had 1-minute timeouts several times a day. When it happens, I can check my watch, click the browser's STOP, and no matter how many times I retry during that 1 minute, it will not connect until the minute is done.
