Troubleshooting Help Needed | Unable to Discovery one specific Windows 10 computer

Hello,

I am facing a challenge in discovering a Windows 10 computer. Below are the troubleshooting steps that I have performed so far:

- Ran Ping from mid server host was successful

- Ran Telnet from mid server host to verify which ports are open

    WMI: 135 - Open

    SSH: 22 - failed

    VCenter: 443 - failed

    WinRM: 5985 - Open

    WBEM: 5989 - Open

    LDAP: 389 - failed

- Ran Tracert works using the name and IP - both result in the expected results

- Verified the user account stored in ServiceNow credentials is a member of the local administrator's group on the computer

- Used "Test credentials" link within ServiceNow. The test fails. However, I CAN successfully log into Windows 10 directly on the computer via RDP. I do not believe there is an issue with the credentials stored in ServiceNow because they work on hundreds of other devices.

- Verified that WMI is allowed on the local firewall

- Unable to verify WMI connection via PowerShell command (gwmi) from mid server host. Results in "Access is denied"

- Checked with DNS admin and they stated the DNS entry is correct.

- I am able to discover another on the same network segment without any issues.

There is something different about the configuration of this one specific computer that I can't seem to figure out. I was hoping that someone with a little more experience might be able to help me out with the next steps.

Thanks in advance!

Is domain included in your Windows credentials?If not can you give a try by adding domain information to Windows credential username like Domain\UserName

Yes, the domain is included in our Windows credentials.
