Does anybody know why my Windows Server 2003 loses its default gateway time to time,even without restart?
Fail-back Support for Default Gateway Changes In TCP/IP for Windows Server 2003 and Windows XP, when dead gateway detection changes the default gateway, the new default gateway remains the primary gateway for default route traffic until dead gateway detection switches to the next one in the list (cycling through the list of default gateways) or until the computer is restarted. Therefore, dead gateway detection in TC/IP for Windows Server 2003 and Windows XP provides a fail-over function, but not a fail-back function. The lack of fail-back for default gateways can cause throughput problems on a subnet containing two routers: a high-capacity primary router and a lower capacity backup router. If the high-capacity router has a temporary failure, dead gateway detection could cause hosts on the subnet to switch over to the backup router. When the high-capacity router becomes available again, none of the hosts on the network use it because they have switched to the backup router. The Next Gen
