All About RPCPING Windows command

The Windows rpcping command is a powerful tool for troubleshooting RPC communication issues. It allows users to test connectivity, verify RPC endpoint connectivity, and diagnose various RPC errors. By using rpcping, users can easily identify and resolve connectivity problems, ensuring smooth communication between different network components. The command provides detailed information about the RPC connection, helping users pinpoint the source of any communication issues quickly and efficiently.

RPCPING Syntax:

rpcping [options] [parameters]

Options:

Option	Description
-t	Specifies the number of retries
-o	Specifies a timeout value in seconds
-u	Uses UDP instead of TCP
-e	Enables extended reporting
-s	Shows status of RPC service on server
-l	Specifies the log file path

Parameters:

Parameter	Description
target	Specifies the target server for RPC testing
port	Specifies the port number for RPC testing
protocol	Specifies the protocol to use (ncacn_np, etc.)
endpoint	Specifies the endpoint to bind to
service	Specifies the service to use (e.g., svcctl)
authlevel	Specifies the authentication level to use
authntication	Specifies the authentication service to use
secqos	Specifies the security quality of service
serverspn	Specifies the SPN to authenticate with
securechannel	Specifies whether to use secure channel for RPC
commonendpoint	Specifies a common endpoint for all interfaces

Caution

It is recommended to exercise caution when using the rpcping command as it can directly impact the RPC services on the target server. Make sure to carefully review the options and parameters before running the command to avoid unintentional disruptions.

RPCPING CMD Examples:

Query RPC Endpoint on a Remote Server

rpcping -s <RemoteServerName> -e 135

Queries the RPC endpoint on a remote server using port 135.

Test Connectivity to a Specific Port

rpcping -t ncacn_ip_tcp -s <IPaddress> -o 0 -t ncacn_ip_tcp -q "<UUID>" -a privacy -ep <EndPointName>

Tests connectivity to a specific port on a remote server using the specified endpoint.

Check RPC Active Directory Response

rpcping -s <DomainControllerName> -o 1 -MSA

Checks the RPC active directory response on a domain controller.

Test RPC Connectivity over TCP/IP

rpcping -s <ServerName> -o 1 -n 1 -a 9 -u 10 -v 3

Tests RPC connectivity over TCP/IP with the specified settings.

Verify Active Directory Replication over RPC

rpcping -s <DCName1> -o 32 -t ncacn_ip_tcp -q "<UUID>" -a integrity -ep <EndpointName>

Verifies Active Directory replication over RPC using specified parameters.

Check RPC Connectivity Using Specific Authentication

rpcping -s <ServerName> -o 1 -MSA -e 1 -a integrity

Checks RPC connectivity on a server using specific authentication mechanisms.

Tip

When using the rpcping command in Windows, make sure to carefully review the available options and parameters to ensure the command is executed correctly.

How do I use rpcping in Windows?

To use the rpcping command in Windows, execute the following command:

rpcping /t ncacn_http -s localhost -o 1 -I 0 -H 1 -t ncacn_http -o RpcHttpConnectionA_Info

What is the purpose of rpcping command in Windows?

The rpcping command is used to check the RPC connectivity to a specified server.

How can I specify the server to test RPC connectivity using rpcping?

You can specify the server to test RPC connectivity with the -s option followed by the server name or IP address. For example:

rpcping /s example_server

How do I specify the protocol to use with rpcping command?

To specify the protocol to use with rpcping, you can use the -t option followed by the protocol type. For instance:

rpcping /t ncacn_ip_tcp

How can I set a specific option value with the rpcping command?

You can set a specific option value using the -o option followed by the desired value. For example:

rpcping -s localhost -o 1

How do I troubleshoot RPC connectivity using rpcping in Windows?

To troubleshoot RPC connectivity using rpcping, you can include options like -I (ping interval) and -H (ping count) in the command. Example:

rpcping -s example_server -I 5 -H 10

Can I test RPC connectivity over a specific port with rpcping?

Yes, you can test RPC connectivity over a specific port by specifying the port number using the -80 option. For instance:

rpcping -s server.example.com:135

How do I get detailed information about the RPC connection using rpcping?

You can get detailed information about the RPC connection by including the -o option followed by the RpcHttpConnectionA_Info value in the rpcping command. Example:

rpcping -s localhost -o RpcHttpConnectionA_Info
