Fixing Win32 Error 0x000006DB (RPC_S_INCOMPLETE_NAME)

The error code 0x000006DB translates to RPC_S_INCOMPLETE_NAME. This error message indicates that the RPC call failed because the client provided an incomplete or invalid name for the server or a remote interface.

Understanding Naming in RPC:

• In Remote Procedure Calls (RPC), communication happens between a client and a server.
• To identify the target server and the specific functionality (interface) to invoke, clients use names. These names can include server hostnames, network addresses, and interface identifiers.
• The RPC_S_INCOMPLETE_NAME error occurs when the client provides a name that is missing essential parts or is formatted incorrectly.

Reasons Behind RPC_S_INCOMPLETE_NAME:

There are a couple of reasons why you might encounter this error:

• Typos or Missing Information: The client code might contain typos in the server hostname, network address, or interface identifier. It’s also possible that essential parts of the name (e.g., port number) are missing.
• Incorrect Name Format: The format used to specify the name might be incorrect or incompatible with the server’s configuration.

Resolving RPC_S_INCOMPLETE_NAME:

1. Review Client-Side Code:

   • Examine the part of your client code responsible for specifying the server name and interface name for the RPC call. Look for typos, missing information, or incorrect formatting.

2. Consult Program Documentation:

   • Refer to the documentation for the program or service you’re trying to access remotely. It should specify the correct format for server names and interface identifiers used in RPC calls.

3. Server Administrator Communication (if possible):

   • If possible, communicate with the server administrator to confirm the expected format for server names and interface identifiers in RPC communication.

4. Software Vendor Support:

   • If the issue persists, consider contacting the software vendor’s support for the program or service. They might have insights into specific naming conventions or troubleshooting steps for their software.

Additional Tips:

• Some RPC development tools or libraries might offer functionalities to validate or construct server names and interface identifiers for RPC calls.
• Debuggers or logging mechanisms can help capture details about the provided name in the RPC call and any error messages related to incomplete names.

By understanding the role of names in RPC and the reasons behind incomplete name errors, you can identify the root cause of the issue with the client-provided name. Reviewing client-side code, consulting program documentation, communicating with the server administrator (if possible), contacting software vendor support, and utilizing RPC development tools (if applicable) can help address this error.
