I have approx. 200 windows XP Pro. computers that are mapped to shares on a Server 2003 Standard OS on my server. The problem is the mapped drives disconnect at random times and random drives. The only way to reconnect the drives is to restart the machine. I receive the error “System Resources Unavailable”. NIC drivers are updated. I have turned off the power settings on the NIC local machines. I have set the autodisconnect on the server to autodisconnect-1 and turned off the power settings on the NIC on the server. This is random throughout the organization. I need any and all help as this is causing quite the issue. Any suggestions?
