I have several workstations with this error:
Windows cannot determine the user or computer name. (Access is denied. ). Group Policy processing aborted.
They also cannot pull up \\servername as access is denied.
I inheritied this network and the first thing that I did was change all passwords. I don't know if this condition existed prior to the password change or not.
One server (dns, AD, etc) and 20 workstations.
