VMware vCenter Server


If you are installing vCenter Server, you may experience the following issues:
  • vCenter Server installation fails
  • vCenter Server installation fails when the installer attempts to install the VMware Active Directory Application Mode (ADAM) instance
Note: The Network Service account inherits permissions from the Everyone account. You do not need to modify permissions for the Network Service account if the Everyone account has Read permissions.


VMware vCenter Server 4.0.x
VMware vCenter Server 5.0.x
VMware vCenter Server 4.1.x


This issue occurs because the Windows Network Service account does not have Read permission on the root drive of the directory where you are installing vCenter Server.
To add the Network Service account with Read permission:
  1. Right-click the root drive and click Properties.
  2. Click the Security tab.
  3. Under Group and user names, click Add.
  4. Type NETWORK SERVICE and click OK.
  5. Select Allow for the Read permission for the Network Service account in the Permissions for Administrators pane.
  6. Click Apply and then click OK.
To update permissions on the VMware VirtualCenter registry key:
Note: This procedure modifies the Windows registry. Before making any registry modifications, ensure that you have a current and valid backup of the registry and the virtual machine. For more information on backing up and restoring the registry, see the Microsoft Knowledge Base article 136393.

If the above steps do not resolve the issue, rename or remove the ADAM folder:
  1. Remove the host from the domain.
  2. Rename or remove the %SystemRoot%\ADAM folder.
  3. Re-join the host to the domain.
  4. Re-install vCenter Server.
