I have (2) 942-L, and (1) 5222-L on one network.  port forwarding set on router; (942) 192.168.1.3:1024, (942) 192.168.1.4:1025, and (5222) 192.168.1.8:80.  no matter if all 3 are connected to dViewCam, only two will work at a time.  Disconnect any third, and they work fine.  reconnect 3rd, and one disconnects intermittently.  On a side note, if I run a different program on another computer (iMac); i.e. IP Camera Viewer, they all work fine.  I know, I know, but I like DViewCam, because it's the only thing running the PC computer.  Any help would greatly be appreciated.  I'm not to tech savy.
Thank you,
Steve
