Gateway is Missing in Windows Server 2008

The default gateway is missing in Windows Server 2008 after the computer restarts

Windows 2008 sunucularda restart sonrası gateway adresinin kaybolması durumu oluşabilmektedir.

Çözüm yolu olarak aşağıdaki işlemler uygualanabilir.

Sorun Registry'de HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<GUID>\DefaultGateway paremetresinde boş karekterlerin oluşmasından kaynaklanmaktadır.

Bu değerin içerisine girilerek boş karaterler temizlenmeli sonrasında manuel olarak gateway ip si girilmelidir.

Consider the following scenario:

• You use the netsh command to enable a network interface on a computer that is running Windows Server 2008 or Windows Vista. The computer retrieves IP addresses from a DHCP server.
• You use the netsh command to set a default gateway for the network interface.

In this scenario, the default gateway is set successfully. You can verify it by running the ipconfig /all command. However, the default gateway of the network interface is missing after the computer restarts. If you double-click the following registry entry, you find that a null character exists in the value data of the DefaultGateway subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<GUID>\DefaultGateway

Note <GUID> is the interface value of the network card.
