Description

The following error message appears when doing a discovery job:

201 Access denied when connecting - Namespace = root\cim

Environment

N-able N-central

Solution

In order to simulate WMI response from probe to target device, run the wbemtest tool on probe.

Remote to the probe and perform following steps:

1. From the Windows Start menu, click Start > Run.
2. Type wbemtest and click OK.
3. Click Connect.
4. Type \\TARGETIP\root\cimv2 in the Namespace field (where target IP of the device you are trying to add in N-able N-central on the probe's network).
5. Enter the user domain\user and password.
6. Click Connect.

The error you will get should be corrected before you can run discovery jobs. You will want to ensure that:

• The probe is in the same domain.
• The probe has admin credentials.
• DCOM permissions are enabled as per the Service Displays a 205 or 201 WMI Error article.
