Not Discovering MAC address nor Domain on Windows Servers

dthenderson · ‎04-03-2017

I've been disabling WMI parameters in order to remove some of the routing CI's that get created, but I am no longer getting MAC address nor Domain for my Windows Servers?

I've been trying to re-enable some of the things that I've touched, but I don't seem to be having any success getting those to populate on the Windows form.

The fields are OOB os_domain and mac_address.

Anybody run into this problem?

Yep!! This is the reason ServiceNow stores Mac address in Network adapter table because a single device can have multiple MAC address. And the WMI path we have used only will pick the MAC addresses so we can not predict its physical or virtual.

You can use Powershell probe with that get-wmiobject command which you showed above in the thread. But you need to parse the result from the XML payload I feel that is complex and unnecessary. Instead, if you see the MAC address in the Network adapter table you can write a business rule based upon your condition you can copy the physical mac address into the server table mac_address field.

Hi Terry,

If you have edited the OOB probes and still you want to be in the older way then you can restore it back by versions.

Versions will capture the changes you have performed in the OOB probes.

To know about - Versions

To revert it back - Revert a change

Thanks for the reply Vivek, but I am really hoping to pin point which probes should be capturing os_domain and mac_address. I could then begin to troubleshoot why I'm not getting that data on my server records.

Hi Terry,

You can discover os_domain by two ways one is NBT and the other one is WMI. Whichever best you can choose by setting this below property.

We will get NBT hostname and domain name in the Shazzam phase of discovery, Also it works only if port 137 is open. If you are choosing WMI then from Windows-Classify probes will give you the information of os_domain.

ServiceNow will store the mac address in the Network Adapters table like below. It won't store directly into Server table.

During Identification phase Windows - Network probe will identify the mac address and it will update in the Network adapter table.
