Getting random disconnects from network drives, but not from Internet.
Turned off power management for NIC and even replaced NIC to still have issue.
Checked EventViewer for errors and there are two errors repeating:
Error ID 5719
This computer was not able to set up a secure session with a domain controller
in domain TITLEMARK due to the following:
Error ID 1054
The processing of Group Policy failed. Windows could not obtain the name of a
domain controller. This could be caused by a name resolution failure. Verify
your Domain Name System (DNS) is configured and working correctly.
This is the only machine to be having this problem. Ran a scan on the network and there are no IP address conflicts. Machine has been on the domain for over 18months without issue. Machine is running on Windows 7 Pro and server is SBS 2011
