When you install a Windows 2000 Server, the RRAS service (Routing and Remote Access service) is installed but disabled.

You can use the Routing and Remote Access snap-in to right-click the server and press Configure and Enable Routing and Remote Access.

Using PsExec, you can run the following batch script to configure RRAS:

@echo off
@echo REGEDIT4>%TEMP%\ConfigRRAS.REG
@echo \[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\]>>%TEMP%\ConfigRRAS.REG
@echo "ConfigurationFlags"=dword:00000001>>%TEMP%\ConfigRRAS.REG
regedit /s %TEMP%\ConfigRRAS.REG
net start RemoteAccess
