i have my sharepoint setup, and am rolling it out to the users. on some PCs, i've experienced "401 Unauthorized" when the user is trying to connect.
ie I have full access, and have granted access to a few users (read). one user, it logged in straight away, didn't prompt for username or password. then, for another user, he was prompted for his username and password. but it gave him the 401. Also, i went logged on to another PC, and it gave me the 401. Could set up of browsers be causing the issue? Any suggestions ? thanks
