Ihave two DCS 950 cameras that have been running strong for 3 years now.  All of the sudden I cannot view them internally or externally.  When I ping the cameras ip address I get a response but when I try to view internally by going to browser and typing in the IP address like I always do, it cannot find it.  When I rerun the setup wizard, it finds nothing.  I havent changed a thing on this network or router???  
ANY ADVICE please!!!!
Also with other cameras I am getting that annoying error " users exceeded 10" message everyone else has been getting.  have to unplug and replug BUT i can deal with it, becuase I can still view
Thanks in advance for any ideas
