Discovery credentials issue with my Windows 10 host

Hi all

I'm having an issue testing Discovery credentials with my Windows 10 host.

Windows 10 is the same host where MID Server in configured/running. I read some comment this approach usually fails and I was wondering if there is a way around this issue?

My MID server is properly configured and both Windows Service and MID Servers are running on both Windows and ServiceNow side.

When I click "Test Credential" it comes back with the following

Credentials I have provided are local user admin account named "Valon"

MID Server is successfully registered and validated in ServiceNow instance

Validate the WMI ports between the MID Server and the Windows 10 hosts are open (including firewall on the Windows 10 host). Port 135 from the MID Server to the Windows 10 host must be open for initial communication AND high ports 49152 - 65535 must be open for the remainder of the communication.

Different high ports are required to be open depending on the Windows OS Version. For example, ServiceNow discovery initiates communication to Windows Server (2000, 2003, and XP) on port 135 from the MID Server to the Windows Server AND completes the communication using high ports 1025 – 5000.

ServiceNow Discovery Windows High Port Ranges Based on Operating System:

Port Ranges: 49152 – 65535 (Windows Server 2008 and later versions, and in Windows Vista and later versions)

Port Ranges: 1025 – 5000 (Windows 2000, Windows XP, and Windows Server 2003)

Valon,

As Rakesh mentioned, validate your credential outside of ServiceNow discovery. The Authentication failed error message you are getting might have nothing to do with the Credential but could be WMI or Firewall issues. The steps to validate the credential are as follows:

1) Log into the server where the MID Server Service is installed.

2) RDP from the MID Server to the Windows 10 host. There are several ways to launch RDP from the MID Server:

-From the command line, type mstsc and select enter…or

-In the Windows search box on the taskbar, enter Remote Desktop Connection and select enter... or

-Select the Windows+R keys and input mstsc and hit OK.

3) In the Remote Desktop Connection dialog box, fill in the Computer (IP address of Windows 10 host) and Username. Select the connect button.

4) Enter the credential in the next dialog box and select the OK button.

5) If you get the "The identity of the remote cannot be verified. Do you want to connect anyway? select Yes.

If you successfully connect, then you know you have a valid credential - and you can move on to other troubleshooting steps.
