my father was given a computer i believe used to be apart of a network, and i'm having issues installing and accessing certain programs on the operating system. i'm constantly be prompt to give an administrator's username and password but the ones i've been given don't work. i keep receiving this error, "there are currently no logon servers available to service the logon." is there anyway to get around or fix this?
this computer has win vista and every other computer in the house has xp. i really don't want to reformat or upgrade.
