Here's an issue.
I have a Mac Pro setup with Leopard server (10.5.3) and FMS 9.0.3.326, and everytime i install the software, SOMETHING corrupts mDNSResponder, resulting in the helper either being deleted or changed or some other unknown issue resulting in a system-wide shutdown of all printing systems, networked and local, and if any reboot attempt is made the machine gets caught in a loop of trying to load mDNSResponder and can't, it continually says its not there. I tested this on a system with a completely clean install of the OS, mated with a completely clean install of FMS, and any attempt to set up print serving on the same machine results in catastrophic failure.
This is extremely frustrating, and any suggestions would be appreciated.
