All network Printers dissapeared from Active Directory

Environment info:
W2K3 - print servers (3), domain controllers (2)
A/D  and Domain functional level : 2003

We had a very weird issue today, all network printers disappeared from AD, no matter what OU they were in. I went to the print servers (we have 3) and checked - all the printers were still there, still shared, etc. I clicked on the properties of one printer, unchecked sharing, clicked ok. I went back in and re-shared it. After a minute or 2, a search in AD revealed that one printer that I deselected and re-selected.

I then decided to try rebooting the print server. About 5 minutes after rebooting, all printers on that print server 1 were now showing up when doing a search in AD for all printers. The printers were not in their correct OUs.

I then rebooted Print severs 2 and 3, printers re-appeared in AD. i then moved all the printers to their correct OUs.

I did some research, and it seems that a GPO setting might have something to do with this. Under Computer Configuration>Administrative Templates>Printers. Both our DCs are configured this way:

Allow printers to be published: Not Configured
Allow pruning of published printers: Not Configured
Automatically publish new printers in AD: Not Configured
Check published state: Not Configured
Directory pruning interval: Not Configured
Directory pruning priority: Not Configured
Directory pruning retry:Not Configured
Log directory pruning retry events:Not Configured
Printer browsing: Not Configured
Prune printers that are not automatically republished: Not Configured
Allow print spooler to accept client connections: Not Configured


So has anyone had this happen, and should I change the GPO for any of the above settings?
