Random disconnects from server/network drives

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:

NETLOGON
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:
%%1311

AND

Mirosoft-Windows-GroupPolicy
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

To check whether its a profile related issue ... login as administrator and map drives and check whether they are getting disconnected.

If the drives are not getting disconnected then rename the local user account(in registry too) . Reboot and let the user login.

Try clean boot.

Clean boot process

Start-type - msconfig- click on startup tab- click disable all...then click services tab- put a check on hide all microsoft services ...and then click disable all....click ok and then restart the computer in normal mode.

If everything works fine in clean boot then enable five startup items and services at a time to find the faulty software.

Found it may be related to a program. User said it would disconnect with the program opened or closed, but for kicks I had her not open the program all day and she hasnt lost the connection.

Thanks for all the help.
