Agent Installation - Knowledge Base

Access Denied

Problem

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

Cause

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.

Resolution

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:

1. Click the Admin tab
2. In the Global Settings section, click Scope of Management
3. Click Edit Credentials
4. Select the required domain
5. Select Workgroup as the network type
6. Specify the following:
   • Admin username
   • Password
   • DNS suffix
7. Click Update Domain Credentials

You have modified the domain credentials.

For client computers which have the operating system Microsoft Windows Vista and later versions, you are required to disable either the User Account Control (UAC) or the remote UAC in all client computers:

Disabling UAC in the client computers

You are required to disable the UAC feature in all client computers. To disable the UAC feature, follow the steps given below:

1. Click start>Settings>Control Panel>User Accounts
2. Disable the UAC settings

   For Windows 7 and Windows 2008 R2

   1. Click User Account Control Settings
   2. Drag and choose the control level to Never Notify
   3. Click OK

   For Windows Vista and Windows 2008

   1. Click Turn User Account Settings On or Off
   2. Uncheck the Use User Account Control (UAC) to protect your computer checkbox
   3. Click OK

3. Close the Control Panel window.

This will disable the UAC in the client computer. You need to perform the same steps in all the client computers that has Windows Vista or higher manually.

Disabling Remote User Account Control in the client computers

You are required to disable the Remote UAC feature by changing the registry entry that controls the Remote UAC feature. To disable the Remote UAC feature, follow the steps below:

1. Click start>Run
2. Enter regedit
3. Click OK
4. Navigate to HKEY_LOCAL_MACHINE \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system
5. Right-click on the white space and click New>DWORD Value

   Note: If this key name is available then right-click on the name>Modify and follow the steps given below.

7. Click Modify
8. Change the value data to 1
9. Click OK

You have disabled the Remote UAC feature.

For an Active Directory setup

If you have an Active Directory setup, you must specify credentials that have administrator privileges, for a domain, to avoid seeing this error. The administrator credentials are specfic to an Organizational Unit (OU). You cannot use the administrator credentials of one OU to complete operations on computers that belong to another OU.

Setting Admininstrator Credentials for Desktop Central Server Services Running on Specific Operating Systems

You are required to run the Desktop Central server service as a domain admin user if you have installed the Desktop Central server on a computer with either of the following operating systems:

• Microsoft Windows Vista
• Microsoft Windows 2008
• Microsoft Windows 7
• Microsoft Windows Server 2008 R2

Follow these steps to change the login account of the Desktop Central server service.
