After changing out my router, I began having problems with my Brother network printer. It took plenty of troubleshooting to eventually get the printer going, just to have it quit on me again. To exasperate the problem, I kept getting "ghost" printers listed. I finally went into the registry and deleted every printer instance listed under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers. After a reboot, I reinstalled the printer once more.
This finally resolved the problem, hopefully once and for all. All the phantom printers are gone as well.
Scuzzy; lost and confused, but not defeated.
