Whatever was happening has disappeared for the moment, BUT

 

Started with printer issues. My MBP and MP are connected through an 811n hub to an HP laserprinter and a Brother laserprinter. All had been working well for a long time until maybe a few months ago, then mysteriously, periodically, one or other of printers "could not be found" by one or other computer. Nothing had been changed, the IP addresses of the printers had not changed, and Terminal could ping the "not found" printer. Dropping and re establishing the printers did not help, and then, suddenly, after hours of flailing about, the computer or computers would typically "find" the printer and all would be fine. This happened less than weekly for a long time. Very aggrevating. Today it happened again, so I decided to check support communities. Logged on as usual, except using a new password Apple had asked me use. Log on went fine until message read "this user id is already associated ... choose another id." Called Apple and support suggested I "reset Safari". After reset, log on went fine using my old password!! Tried printers, and once again they all work. Do I have a virus, or what?

 

Mac Pro and MBP are both current on OSX 10.7.3

    You have a "what"!

     

    Are you using a router?  Maybe a dns caching or some other caching problem.  Not sure, but it isn't a virus.

    I am not sure about the router.  What would happen if you reset it?

    If the Macs and the Printer are on the same subnet (have addresses in about the same range, which these do) the Router does not intervene, it only Bridges (passes the packets) wireless to wired without changing anything.

    Is this an intermittently defective D-Link?

    If you are passing out DHCP Address in the same range, you may occasionally give your Mac the same IP Address as the printer. The manual IP Addresses and the automatic TP Addresses should be a little different.

     

    For example, my printer is at 192.168.0.17 manually

    The first IP Address assigned automatically is 192.168.0.101
