We have NW6.5sp5 running 40 printers via iPrint client v04.15. I installed an updated Xerox NDPS downloaded from Xerox to the print server. I immediately lost access to the networked printers. Broker and NDPSM both are still running and can access printers. I can still ping the printers via the network. Attempts to print fail. iManager fails to load. iPrint web page fails to load.

I was not involved with the original install and config and am new to this area. Any help would be appreciated.
