Unknown issue

[solopubblicita]

We have installed lansweeper freeware in our network on a dedicaded computer.
We have something like 1000 computers.
Lansweeper was able to connect only to one half of the computers.
The error that affects most of the computers is RPC server unavailable.
We read previous issues about the subject and managed to fix some of the computers.
Now we have still some problems on 119 PCs.
As a matter of fact, after applying all the possible hints, if we run lansweeper connection tests is says \\root\cimv2 remote wmi access failed "valore non compreso nell'inervallo" ( it's italian, it'd sound translated that the value is not inside the interval) we have the same answer in remote registry test using WMI.
We don't know what to do. is there anybody who managed to solve this issue?
Thanks in advance for the answers.

Yes, We tried and more than once.
Everything seems to work fine on the machine. During the procedure a Microsoft tool is called to check the connetion to the repository.
As shown in he attached pictures we are able on the local machine ( via DameWare) to access root/cimv2.

Unfortuantely there was no error code at all.
Anyway, here is the screenshot.
