We have configured 12 Preferred Servers in our LANDesk 8.8 SP3 Console and entered the same username and password for each. However, 3 out of the 12 fail UNC Authentication. We have triple checked the username and password is correct. We have re-created them from scratch and closed/reoepened the Console to no avail. We know these 3 servers are up and working as normal because machines have been LANDesk imaged and software deployed from them and the core can ping them and vice versa. Software distribution appears to working as normal so we're not sure what problems this lack of authentication may cause.
Where are we going wrong please? Perhaps there's a logfile we can check for more info to help us locate the problem?
