Error Message:

Cannot open an anonymous level security token.

Explanation:

An attempt was made to open a client's anonymous-level security token. A token must have an impersonation level of at least "Identification" to be opened.

User Action:

Contact the supplier of the running application. A general workaround, if the application interface allows it, is to avoid trying to open the anonymous token, or to specify a higher level of impersonation for the client program.
