Windows 2008 IPv4 gateway keeps disappearing after reboot…

WindowsLogo

Config:

Windows 2008 Std/Ent Sp2 x86

Summary:

After reboot of system, the system stops responding to pings and RDP. When accessing IPv4 settings, the gateway is missing, and will blank out every time.

Workaround:

  1. Regedit
  2. Navigate to HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interface/%CLSID%
    • %CLSID% = A unique ID that is associated with each network adapter that you have on the machine. You should have one for each adapter installed on your server.
  3. Change the "DefaultGateway" Regkey and manually type in the correct IP.
