0x000006d1 – Rpc_S_Procnum_Out_Of_Range – the Procedure Number Is Out of Range

The "0x000006d1 – Rpc_S_Procnum_Out_Of_Range" error happens when a program tries to call a function that doesn't exist, causing problems between the computer that sends the request and the one that receives it.

This can happen if the numbers assigned to functions don't match, if the server has been updated recently, or if there are setup mistakes. You might notice your programs crashing, having trouble connecting, or running slowly.

To fix this, make sure both computers are set up correctly and updated. Keeping everything updated and checking your network can help stop this from happening again.

Error meaning:

The error "Rpc_S_Procnum_Out_Of_Range" means that the number for a procedure in a remote call is not valid.

This happens when the number is too high or too low, causing the server to not understand the request.

Causes:

Reasons for "Rpc_S_Procnum_Out_Of_Range" Error:

  1. The client and server have different procedure number assignments.
  2. The server has been updated, changing procedure numbers that the client doesn't know about.
  3. There are configuration settings that are not set up correctly.
  4. The client-server interface is outdated.
  5. The client is trying to call a procedure that the server does not recognize.
  6. There are network problems, like connectivity issues or timeouts, affecting communication.
  7. The client and server settings are not properly synchronized.

Symptoms:

When users see the "Rpc_S_Procnum_Out_Of_Range" error, they might notice these problems:

They can't connect to the service they want to use.

They see error messages saying the procedure number is out of range.

Some applications might crash or freeze, especially when trying to run certain commands.

System logs may show the same error happening over and over.

Some applications might run slowly or act strangely.

Users might find it harder to get their work done because of these issues.

Solutions:

Step 1: Check the RPC Server Configuration

Make sure that the procedure numbers being called match what is defined in the server's interface.

Step 2: Look for Recent Changes

See if there have been any recent changes in the server code or updates that might have changed the procedure mappings.

Step 3: Confirm Compatibility

Ensure that the client application works with the server's RPC protocol version.

Step 4: Restart RPC Services

Try restarting the RPC services to fix any temporary errors.

Step 5: Review System Logs

Look at the system logs for any other error messages that might help you understand the problem better.

Step 6: Consult Documentation

If the issue is still not fixed, check the relevant documentation or support resources for further help specific to your situation.

Impact:

The "Rpc_S_Procnum_Out_Of_Range" error can affect a system in several important ways:

  1. Communication Issues: It prevents systems from talking to each other properly.
  2. Application Failures: Programs may stop working or crash because they can't complete tasks.
  3. Slow Performance: The system might run slower, making it hard for users to get things done.
  4. Service Interruptions: Users may find that they can't access services or tools they need.
  5. Wasted IT Resources: IT teams have to spend time fixing this error instead of working on other important tasks.
  6. Data Problems: In serious cases, it could lead to mistakes with data or even loss of important information.
  7. Financial Impact: Companies may lose money if their systems are not running smoothly.

Fixing this error quickly is important for keeping everything working well.

Relevance:

The "Rpc_S_Procnum_Out_Of_Range" error is important in Windows operating systems like Windows 7, Windows 8, Windows 10, and Windows Server versions.

It happens when there is a problem with Remote Procedure Calls (RPC), which help different programs talk to each other over a network.

This error can cause issues in programs that rely on RPC, especially in places that use cloud services or microservices.

It's crucial for organizations to fix this error to keep their systems running smoothly.

Prevention:

To avoid the "Rpc_S_Procnum_Out_Of_Range" error in the future, follow these simple steps:

  1. Update Software Regularly: Always keep your software and protocols up to date to match the latest standards.
  2. Test Applications: Check all networked applications thoroughly before using them to catch any issues early.
  3. Keep Accurate Records: Write down procedure numbers and their services so you can easily troubleshoot if something goes wrong.
  4. Monitor Your Network: Set up a system to watch for any strange activity related to remote procedure calls.
  5. Train Your Team: Teach everyone about good network management practices to help prevent mistakes.

People Also Ask

Are There Specific Systems Prone to This Error?

Some systems, especially those using old or poorly set up Remote Procedure Call (RPC) frameworks, are more likely to have procedure number errors. Keeping software updated and following good practices can help prevent these problems.

Does This Error Affect Hardware Performance?

Errors with procedure numbers usually don't hurt how hardware works. But they can cause apps to not work right or make the system unstable. This can lead to a slower experience for users and make the hardware seem less efficient.

Can This Error Be Logged for Future Analysis?

Yes, we can log this error for future review. By keeping track of the error details, we can gather useful information. This helps us figure out what went wrong and see if it happens again, making it easier to fix problems.

What Are the Common Misconceptions About This Error?

Some people think this error is only about network problems. They might not see that it can also be caused by software not being set up correctly. It's important to check the procedure numbers in the app to avoid this error from happening again.
