Alert Security Systems

I did have to switch computers after my old one failed.

I am running the latest and greatest software on my pc. 

For some reason the pc can find 3 of my 6 cameras.

Is there anything I can do to fix it? If so what?

When you look from the web, do you see just 3 there too ?  If so, have you power-cycled the 3 missing cameras ?  What do the camera status lights show on the 3 missing ones ?  Is the PC running via ethernet cable or WiFi ?  ...just trying to narrow down the variables here.
