I have a shared folder named \\SHARE which is replicated in another server named \\REMOTE

In case of disaster, just change IP address of SHARE in DNS and point it to REMOTE Server IP, so i can access \\SHARE and see what is in REMOTE server.

I did it before in windows 2003 and 2008, but i can't do it in Windows 2012 R2.

The steps i follow are: - Change IP address of SHARE in DNS and point it to REMOTE Server IP

To configure this in REMOTE server i used to add SHARE name in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\OptionalNames But i can't find it in windows 2012R2

Answer myself.

It's exactly same as windows 2003 and 2008 but I didn't find it in regedit at the first time.

1.- Edit the registry key


2.- add a value OptionalNames of type Multi-String. Add in a newline delimited list of names

3.- Reboot Server
