Additionally, the Remote Procedure Call service fails intermittently, and you receive the following error message:

Error 1722: The RPC server is unavailable.

Notes

  • This issue also occurs after you install one of the updates that are described in KB 975792 and in KB 2509553.

  • This issue does not occur when one of the following conditions is true:

    • You select the Disable recursion option in the Advanced table of the DNS properties.

    • You restart DNS and DNS Cache at the same time.
