You can see the error message 'Access Denied' on the screen when you try to do either of the following:
- Install an agent remotely using the Scope of Management (SoM) feature
- Complete tasks like scan for patches, inventory or use the remote control feature
You require administrator credentials to enable a Desktop Central server to complete remote operations like agent installation, patch scanning, inventory scanning and use features like the remote control feature. You will see the error message, 'Access denied' if the credentials specified in the SoM do not have administrator privileges.
Note: The causes and resolutions explained in this article are based on our experiences in our production and client environments. However, there may still be a few unknown causes which are not covered in this article. If this article does not resolve your issue and if you have an Active Directory-based network, you can automate agent installation using a startup script.
To resolve this problem, identify the kind of network setup you have and follow the appropriate resolution, specified for it, below:
For a Workgroup setup
In case of a workgroup set up, the credentials specified should have administrator privileges on all the computers in a particular workgroup. To modify the credentials, if required, follow the steps given below:
- Click the Admin tab
- In the Global Settings section, click Scope of Management
- Click Edit Credentials
- Select the required domain
- Select Workgroup as the network type
