RPC_S_INVALID_NET_ADDR - 1707 (0x6AB)
The network address is invalid.
Updated: Feb 21, 2026
Technical Background
The error code RPC_S_INVALID_NET_ADDR is a specific return value from the Remote Procedure Call (RPC) API in Windows. This error indicates that an invalid network address was provided to an RPC function, leading to its failure.
Error Details
- Error Name: RPC_S_INVALID_NET_ADDR
- Numeric Code: 1707
- Hex Code: 0x6AB
- Short Description: The network address is invalid.
This error typically occurs when an application attempts to make a remote procedure call using an incorrect or malformed network address. The RPC runtime environment checks the provided address and, upon finding it invalid, returns this specific error code.
Common Causes
The common causes for RPC_S_INVALID_NET_ADDR include:
- Invalid Parameter Values: An incorrect or improperly formatted network address was passed to the RPC function.
- Incorrect Object Type: The operation attempted is not compatible with the type of object (e.g., a directory operation on a file).
Real-World Context
In practical scenarios, this error might occur when an application tries to connect to a remote service using an incorrect IP address or hostname. For example, if an application attempts to call a remote procedure on a server with a non-existent IP address or a misconfigured DNS entry, the RPC runtime will return RPC_S_INVALID_NET_ADDR.
Is This Error Critical?
The criticality of this error depends on the context in which it occurs. If the application is performing a network operation that requires a valid address, then this error can be considered critical as it prevents the intended functionality from being executed successfully.
How to Diagnose
To diagnose RPC_S_INVALID_NET_ADDR, follow these steps:
- Review Operation Context: Ensure that the network address provided is correct and accessible.
- Validate Parameters: Check the parameters passed to the RPC function for correctness, including the format of the network address.
- Confirm Object Types: Verify that the operation being performed is compatible with the type of object (e.g., a file or directory).
- Verify Input Data: Ensure that all input data, including network addresses, are valid and correctly formatted.
- Check Limits or Constraints: Confirm that there are no system limits or constraints preventing the operation from succeeding.
How to Resolve
To resolve RPC_S_INVALID_NET_ADDR, consider these actions:
- Correct any invalid parameters passed to the RPC function.
- Adjust the network address to a valid and accessible one.
- Ensure compatibility between the operation and the object type.
- Retry the operation with valid inputs.
Developer Notes
Developers should ensure that all network addresses used in their applications are validated before being passed to RPC functions. This can be achieved through thorough input validation logic, error handling, and robust testing.

FAQ
Q: What does RPC_S_INVALID_NET_ADDR mean?
A: It indicates that an invalid network address was provided to an RPC function, leading to its failure.
Q: How can I prevent this error from occurring?
A: Ensure that all network addresses used in your application are valid and correctly formatted before passing them to RPC functions. Perform thorough input validation and error handling.
Q: Is this error related to DNS issues?
A: Yes, if the provided hostname is incorrect or cannot be resolved by the DNS server, it can lead to RPC_S_INVALID_NET_ADDR.
Summary
The RPC_S_INVALID_NET_ADDR error code signifies that an invalid network address was used in a Remote Procedure Call. This error can occur due to various reasons such as incorrect parameter values or mismatched object types. By validating inputs and ensuring compatibility, developers can prevent this issue from arising.
