Problem
I really like Print Migrator, it makes a time consuming laborious task really easy. It’s so good Microsoft don’t use/support it any more, (after Server 2003). So this week when I was migrating printers from an SBS 2003 server to a clients 2003 CRM server, I was really happy, and dragged out PrintMig.
However when trying to restore the printers on the target server this popped up;
Kernel Drivers Blocked
Warning: Kernel Mode Drivers (version 2) are blocked on the target machine. Disable Kernel Mode driver blocking and re-run Printer Migrator. Ignoring this warning (Cancel button) will result in driver installation, but because they are kernel mode drivers – a serious problem with any dependent print queue could potentially bring down the system. Selecting OK will result in a restore termination.
Solution
Option 1 via GPO
1. A quick internet search told me to disable the policy within the servers local policy, but Computer Configuration > Administrative Templates > Printers didn’t exist, so I did it in the default domain policy.
Computer Configuration > Administrative Templates > Printers > Disallow installation of printers using kernel-mode drivers
Set the policy to Disabled > Apply > OK > Close the policy editor.
2. Now on the target server run the following command and try again;
Option 2 via the Registry
1. On the Target server > Start > Run >Regedit {Enter} > Navigate to;
If there is no sub-key called Printers > Create one.
2. Within the Printers Key create a new DWORD called KMPrintersAreBlocked and set its value to 1.
3. Run the PrintMig restore process again.
