We will give you a better understanding of the problem and even show you the various reasons why it occurs. Basically, it is a technology that uses an inter-processing communication technique, which primary purpose is to enable a client computer and a server to communicate over a network. In order for the RPC to properly function, certain services should be running smoothly in the background. If the error shows up, it is likely that some of the RPC-related services may be malfunctioning.
In some cases, this problem may be a result of corrupted registry files. In most cases, our tips can resolve the issue. To ensure that all these RPC-related services are running normally, follow the steps below:. In some cases, the Firewall may be blocking the traffic requested by RPC, hence resulting to the error. What you should do is review the configuration of the Firewall and check if it is preventing the RPC from connecting to a network.
Here are the instructions for Windows Firewall:. You can also use an antimalware tool like Auslogics Anti-Malware.
It is a powerful solution for a modern Windows PC. You could also be seeing the RPC server error because of a network connection interruption. You can check your Internet connection by following these steps:. It is important for your computer to have the right registry settings to ensure that the RPC is running properly. A Window that says Connected does not means that your are really connected.
Connecting to the Router means that you can enter the Router's core IP into an address bar of a browse, be able to connect, see, and configure the Router's menus. Software Firewall application that is Not configured to allow local traffic between the computer and the Router is a possible issue too. If possible configure the Firewall correctly, or totally uninstall it to allow clean flow of local network traffic. If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On.
Paste the content of the Ipconfig. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. I'm a bit confused by your response to Jack's post. Did you ensure the RPC service is running, as Jack suggested? The only problem is I get the following error response when I enter it into the command prompt: An error occurred while releasing interface wireless network connection : The RPC server is unavailable.
This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question Report abuse. This error message may occur if the File and Printer Sharing for Microsoft Networks component is not enabled on the remote computer.
This troubleshooting guide will discuss the events that occur at each phase, how to test these events, and how to identify if the phase completed successfully. Troubleshooting this phase requires verifying that a response is received to the name resolution request and that the response contains the correct IP address for the RPC server. DNS resolution will be occurring at the client so open the network trace taken from the RPC client machine.
You will be looking for one packet that is the query from the client to the DNS server and then the response packet from the DNS server. It will look similar to this:. If the trace does not show a correct IP address returned or you do not see any answer from the DNS server then reference the following resources to help with DNS name resolution troubleshooting. NetBIOS broadcasts are queries broadcast to all hosts on the local subnet so name resolution is limited to only hosts on the subnet.
The handshake should look similar to what is shown below. It was noted earlier that an RPC Server will register itself and listen on a particular port and IP address of the host computer. In the client side trace it will appear as if the server sent the TCP Reset while the trace from the server indicates the client is the source of the TCP Reset.
If the 3-way handshake is successful, continue to the RPC Discovery phase. The RPC Discovery phase will occur one of two ways. The identifier is different depending on which method is used and the RPC client will know ahead of time which method it wishes to use.
This method is a two-step process. Below is a sample of what this would look like and a step by step explanation below it. We will not address the SMB session setup in this document and the TCP session establishment has already been discussed. The troubleshooting steps involved at this stage are largely based on the application reporting the RPC failure. RPC network traffic can take multiple forms. It is important to understand which form is in use in order to identify which TCP session is responsible for the RPC communication.
This session will be used in the RPC Discovery phase to locate the endpoint of the desired application. In this phase, look for failures due to improper certificates, inaccessible Certificate Revocation Lists, or untrusted certificate chains. Some examples of this can be seen with Computer Management or the Remote Registry service.
