Wanted to give a heads-up to anyone else thinking of installing this patch
- put it on last night, rebooted the server and it promptly deleted EVERY
printer off of EVERY workstation.

Here's the fix:
Put the old NLMs back
Say a quick prayer
Reboot the server
Reboot any logged in workstations and printers should return

We use ZENworks in our environment and that helped with restoring the
printers, so we're functional today. I've reported it as a defect, but
flat out refuse to pay $650 for something a simple patch broke.
