# Administrative Option Settings

The optional Administrative Options registry settings allow an administrator to control the deployment of services. These settings reside under the subkey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0\Common\Research\Options

Note These settings cannot be set through the user interface.

Entry name | Value type | Value data | Required? | Default value
--- | --- | --- | --- | ---
NoAdd | DWORD | Boolean used to disable the Add Services button. This setting prevents the addition of any service except the internal services. It also disables the discovery mechanism. Possible values include: True (1). The Add button and discovery are disabled. False (0). The Add button and discovery are enabled. | No | False is assumed if absent.
NoDiscovery | DWORD | Boolean used to disable the discovery mechanism. Possible values include: True (1). The Research task pane never queries discovery servers. False (0). The Research task pane can query the discovery servers. | No | False is assumed if absent.
DiscoveryNeedOptIn | DWORD | Boolean used to ask the user to opt in to the discovery mechanism. This setting is irrelevant if NoDiscovery is set to 1. The HKEY_CURRENT_USER version of this value overrides the HKEY_LOCAL_MACHINE value. Possible values include: True (1). Ask the user to opt in to the discovery mechanism. False (0). Enable the discovery mechanism without asking the user. | No | False is assumed if absent.
