I have a MS network with Win 2008 as DC and 15 workstations with XP. Now I installed some new workstations with Win7, but I can not join them to domain. Error message says: Logon failure: the user has not been granted the requested logon type at this computer. I disconnected one XP workstation and tried re-join the domain, same error message. I installed another Win 2008 server, but also could not join it back to the domain. Other workstations, which are already in the domain, work fine.
Based on previous advices on this site I tried to run ping \\dc (Ok), then net view \\dc (System error 5, Access is denied).
I checked the local policies on DC, Access computer from network is set to (Everyone, Administrators, Authenticated Users, ...)
To be sure, there is no problem with group policies, I ran dcgpofix on DC and deleted links from all other (non-default) GPOs
