Redirecting no longer function

I tried to install Sametime without luck. After I did this the Domino Web Access don’t work properly. I have now changed all the configuration back to the starting point (as it is possible for me to remember), but it is not possible to log on from the Web Access form.

I use dclf.nsf from sandbox and have changed the domcfg.nsf back to the way it was before the Sametime installation.

When the user start a browser session with:

http://server/mail/mailfil.nsf

the public documents are visible as normal and when they click on “login” they are redirected to the usual login form.

After typing in their username and password the form only blanks out and remain on the screen.

If they try to use an incorrect name or password they receive a message about this, so the verification seems to be correct.

What have I missed out. Any suggestions? We use 6.5 as server and clients and all browsers are IE6.
