Built a new WI 3.0 box today to play with and it worked without issue. Might be time to either bounce my WI boxes which have been up the last 6 months or blat the config and put it back.

Try put the following in the registry on the any servers you have in your serverlist within the web interface. 2. Try changing the servers in your serverlist. If this works then chances are one of the servers in your server list is having performance problems. I had this same problem back about 6 months ago and can't remember which one I did to fix it.

If I check the Single sign-on check box. Any users that now go to WI get a page not found error. However if I try the same directly on the WI server it works fine. Ideas? Client setting? Malcolm
