server showing offline on KSC when we change the IP

[Aramanthine]

Hi Guys,

just wanna know if we change the IP of the server that we install KES for windows, does the KSC cant detect the IP Changes and will show the server as offline?

@Aramanthine hello. KSC uses "Device ID" identifier, look at the article https://support.kaspersky.com/ksc/15.1/3912

Dynamic IP for controlled devices isn't a problem for KSC.

The IP address, hostname, and fqdn of the Kaspersky Security Center server should always be static. If you make it dynamic, workstation-to-ksc communication will be lost, you have to run klmover script to reconnect them again , and the KSC certificate will also be invalidated.

However, DB and KSC can communicate. Try using hostname or localhost with an Admin Server connection if the IP has changed.
