Changing a remote system from static to dynamic IP
You may occasionally need to change a remote system from a static IP to a dynamic IP (DHCP). Here's how:
- Open Regedt32 and view the remote registry via File | Select Computer.
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\
Microsoft\Windows NT\CurrentVersion\NetworkCards\1 (or whatever number card you need to change—some machines may have multiples) and record the ServiceName value.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\<ServiceName>\Parameters\TCPIP, where <ServiceName> is the name you recorded in the previous step.
- Change the values of EnableDHCP to 1 and IPAddress And SubnetMask to 0.0.0.0.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\DHCP and change the Start value to 2.
Note: Please remember that editing your registry can be risky; always have a verified backup before you begin.
