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,

We have a similar issue and have performed all the checks (including a wireshark trace) which revealed that there are no firewall or credential issues. The return port used by the target server is 5068 which reaches the mid server, however results in a failed logon attempt. This affects a large portion of the estate as it occurs across one sub-domain.

Any advice would be appreciated as to the best way to fix.
