Removing Corrupted/Missing LPR Ports in Windows 10

SOLVED Check edit

Hi all,

Through a series of unfortunate events, I have a set of computers that have updated to the Windows 10 Anniversary patch. Post-patch everything seemed okay. However, my users started informing me that they could no longer print on those computers. We use an instance of Print Manager Plus as our print server. Prior to the patch, all the computers were configured with the correct LPR ports. However, post patch, those ports are no longer listed in the print management snap in. But, if I try to re-add those ports, I receive an error saying that an identical port already exists. I'm currently combing through the registry to see if there's some obscure place where its still being referenced. I'll take any advise if anyone has experience with a problem like this.

*Edit: Okay I am now slamming my head against my desk. These workstations were being used immediately after the windows 10 anniversary patch was installed. After just performing a restart, the ports are recognized again and everything works. I did not perform the first rule of windows troubleshooting. Goddamnit
