Vista and 8.2:

I changed the default ports on the DVR for Control Center (3389, 5613, 5553).

Control center and remote desktop both fail to start ! (only viewlog runs). Even after full system restart.

Need to this so I can control multiple DVR's behind 1 WAN-IP.

Any idea's ?

Did you change the ports in control center also? (edit button, configure, choose system configure and then network. Or can you not get into it at all?

If going through a router or firewall you need to alter the port forwarding to use the new ports also.

XP and 8.12 +8.2
I have had the same problem for months now , had given up, thinking it was something stupid that I was missing, but now I see I'm not the only one.
Everything works fine using multiview over IE. browser

Be careful with 3388, you would be inclined to change it to 3389 , but that is remote desktop !!!

oeps did not notice the 3389=remote desktop ! (will try a different one).

Kensplace: if I change the numbers on the DVR the service will not even start (I know I have to change it in CC as well).

dcam:
what port numbers did you change: all 3 ? and do you remember witch value's you used.

It look like a bug because the service should start even with port conflicts !

just tested a few combinations on my test system:
Command: 3390
data: 5614
log: 5553

Services do start !

if I use 5613 for data: services fail to start.

Will test at customer site as well and see if I can connect.

above did solve it, according to Geovison the service would not lauch if the port is already in use .....
