Error while integrating new device in windows
Well it means that user as you provided could not access to specific hosts and it comes up with some possible issues.
1- if they are in specific domain and you wrote policy for special user to gather logs from them ,check them and see they takes policy or not .
2- check the network connectivity such as any possible ACL on switches or routers.
3-check the rules on firewall and see WMI ports are opened.
4- check the windows firewall for any deny rules on inbound or outbound traffic.
5- check the antivirus firewall on host. if it is enabled , turn it off and test and if it necessary to turn it on according it your organization policy ,write some rules and make them in exception policy.
I wish i could be of help
