Can not add slave administration server

[kitwo]

Hi, I have problem with my slave administration server in KSC SP3. This slave can not add with reason: "can not add: this administration server already exist in hierarchy". Here you are the picture I checked and there is no double ip address. can someone help my problem please?

Hi, Could you please describe how did you created this slave server? Is it clean installation or you have cloned this server as VM? Thank you!

Hi Konstantin, Previously, this slave was already registered with KSC. Slaves are deleted because the PC is replaced with a new one, but still with the same IP address. When the slave will be added again, there is information as "can not add: this administration server already exist in hierarchy"."
