I have a CNC Mill that is networked in order to gain access to a file folder share. Out of nowhere I can not connect to this file share with the account credentials from that machine. Permissions havent changed, Account isnt locked out. I can use the same credentials at a computer and log in just fine. What is interesting though is I can not ping our DC from that machine. I can ping other pieces of equipment but not our DC. I have only removed print drivers and printers from the DC this weekend. Nothing else that would effect it to my knowledge. I am running server 2008 64bit.
