Problem: In my office, we use ISA with the Cobion-Plugin OrangeBox Web (www.cobion.de), however... Now if I try to login my private OWA at home (my own home-server) the login-window appears, but when i give the right username/password, the login will be denied. But when I uncheck the "Ask unauthenticated users for identification" in "Outgoing Web Requests" in ISA-Server, it works. But as the Orangebox WEB needs to have the user-auth. checked, i can't leave it unchecked.
Any suggestions or ideas?
PS: the config: client: winnt 4, IE6 Server office: w2k server, isa Server home: w2k server, exchange2000
Try removing the checkmark from the "ask unauthenticated users" checkbox. Then make sure that all Site and Content Rules require authentication by user/group or client address set.
