I have a developer with a Windows XP (SP2) 64 bit machine. If the machine is left on overnight (or any period of time longer than 5-6 hours) it takes 2-3 minutes to open any local drive and his network drives are no longer accessible. Here's what the system logs report... Any Help

BTW: The problem just started a week ago and nothing has changed on the domain controller / AD or his machine.

--- ERROR 1 Event Type: Error Event Source: NETLOGON Event Category: None Event ID: 5719 Date: 6/8/2010 Time: 9:17:26 AM User: N/A Computer: BFC1 Description: This computer was not able to set up a secure session with a domain controller in domain UR due to the following: There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.

ADDITIONAL INFO If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.
