Enabling SMB1 or CIFS on Windows Server 2012

Ran into this this week. Even though I hate doing it and definitely don’t recommend it, I had to enable CIFS on a Server 2012 instance. To do this, you first have to install the “SMB 1.0/CIFS File Sharing Support” Feature, and then do the following:

Open the Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer and change the value of DependOnService from SamSS Srv2 to SamSS Srv.

Reboot the server and that’s it! Enjoy your legacy application / device!
