Locate the names of trusted providers

Determine the name of a trusted provider of a plug-in DLL by viewing the details of its digital signature. The string for the trusted provider name must be contained in the certificate's subject.

1. Right-click the plug-in DLL and click Properties.

2. In the Properties window, click the Digital Signatures tab. (If the plug-in is unsigned, this tab is absent.)

3. Select a Name of signer in the Signature list and click Details.

4. In the Digital Signature Details window, click View Certificate.

5. In the Certificate window, click the Details tab and scroll to the Subject field.

   The value displayed for this field is the name of the trusted provider. You can you use any subset or the whole name of any of the names that are part of the subject as the <providername> variable for the /TrustedProviderAdd and /TrustedProviderRemove parameters.
