The error code 0x000006c5, known as Rpc_S_Invalid_Tag, means there's a problem with a tag used for communication between a client and a server.

This can happen if the tag is wrong, if different versions of software are used, or due to network problems. When this error occurs, you might see messages popping up, your apps might crash, or you could have trouble connecting to the internet.

To fix this, check your network connections and make sure the tags are correct. Keeping your software updated can help prevent this error from happening again.

Error meaning:

The error code "Rpc_S_Invalid_Tag" means that a wrong tag was used in a message sent to a server.

This makes it hard for the server to understand the request, causing problems in communication.

Causes:

Potential reasons for the Rpc_S_Invalid_Tag error:

  1. Requests or responses are tagged incorrectly.
  2. The client and server are using different versions that don't work well together.
  3. Problems with the network can interrupt communication.
  4. The application code isn't handling RPC calls properly, causing unexpected tags.
  5. Not enough permissions or security settings are stopping valid tags from being recognized.

Symptoms:

  • Application crashes or freezes
  • Error messages about an invalid tag
  • Confusion and frustration from users
  • Intermittent failures when connecting to remote servers
  • Problems retrieving data
  • Slower response times for the application
