HI,

We always try gwmi connection first when the discovery is initiated. SO couple of the things to check:

1) 135 port

2) then logon to mid server and go to powerShell executor and run

gwmi win32_operatingsystem -computer <IP address of server to gather info> -credential '<credentials>'

3) If this is successful then check firewall rules on that target machine.

Thanks,
Ashutosh

Hi Ashutosh the 2nd point is failing in my case.
thanks

HI,

So now you have to check the permission for that user used. It should be local admin or domain admin with access to wmi. Also check the port 135 is open or not.

Try telnet.

Thanks,

Hi,
We are using the domain admin, wmi access is also configured, we are using 5985 port , ping and telnet is also successful but still after running discovery the error is coming.
Thanks.

Hi,

Did you check 135 port? Also firewall rules on that machine? Sit with network guy and see where the connection is denied.

Thanks,

What is the exact error message being returned? It is an Access Denied error?
