OzPax1, tks, no there is no registry problem I can identify as yet.
fobotsco, tks, I had my share with them about the most unreliable connection. This actually produced half of the investigating time spent. Sorry, but this is not the problem with this system.
heavy metal, tks, am using IE most of the time, NS runs only for testing websites after deployement. No, prob is on both as well as on two more browsers.
Service pack 2 is running since installation.
BTW, I like the announcement from BT on their customer 0800 number when everything collapses and no one can log-in...."Friday 8th of June 2 am, there are no reported problems on the BT network...." this, after at least 3 friends complaint about the unavailability of the authentication server...
Still searching for a solution so...
