When sending an email, here what goes behind the scenes: This is because of the unclear error codes. These errors are, in fact, difficult to deal with. SMTP 554 occurs when you try sending an email to a recipient and the transaction fails mid-way. In this article guide, we’ll explain the top 3 reasons that result in this error and how you can solve it. When sending an email, it’s not uncommon to encounter the SMTP 554 Transaction Failed Error. Under the hood, many servers and protocols keep the environment running which in turn facilitates the exchange of emails from one ID to another. But Email technology is more than the simplicity there is on the surface. Sending and receiving Emails these days is an everyday task. This will result in server issues, mostly the RPC server unavailable error.: SMTP Error "554 Transaction Failed" In case an RPC server’s name is mapped to a wrong IP address, the request might get deviated to a wrong server. All these specifications are needed by the server to respond to the correct machine. ![]() Name Resolution Errors: A procedure call initiated by the user is specified by a name, IP address, and port addresses.In such scenarios, a procedure call from the user’s end fails to reach the server resulting “RPC server unavailable” error. Any damaged component or improper network configuration leads to server unavailability issues. Inappropriate Network Configuration: A network is a combination of PC’s, network cables, peripheral devices, routers, etc.Invalid Windows Registry Settings: RPC requires valid Windows registry settings to function any modified, invalid or corrupt entry will disable RPC services on your machine.Allowing the RPC server to communicate through your Windows Firewall freely is the first thing you must do to solve this issue. It, in turn, blocks the traffic reaching the TCP ports of the Server machine. Windows Firewall: Sometimes a security application within the client machine or any other third-party firewall running on the server denies the RPC Server requests.In this section, we have listed some of the root causes that lead to the RPC Server is unavailable error. A connection disturbance can be easily fixed with a few steps. Still, the most reported one is the improper configuration or disturbance caused in the connection of peripheral devices like printer or scanner. Well, there can be several reasons behind this error. Reasons Behind the "RPC Server is unavailable" Error Any disturbance caused within the network can result in RPC Server unavailable error. RPC plays a crucial role in managing devices across a network. Note: Here, the client system and the server can either be different machines in a network or different processes within a single machine. The following versions of Exchange Server and Outlook prefers the RPC connection.Ī request is initiated by the user, which is then transported to the server via RPC in return, a response is generated by the server and sent back to the user. The clients gain the ability to connect with the email server more securely through the RPC protocol. ![]() It can be considered as a request-response protocol, that can be structured using a Client-Server communication model. The benefit of RPC is that the processes can share the Windows based resources within the same network more effectively. Remote Procedure Call, better known with its short form RPC, is a network-based protocol that connects different Windows processes through the inter-process communication technology. Later we will discuss methods to undo this mere error. First, let’s have a brief introduction of RPC Server and why RPC Server error is caused. However, various other causes lead to RPC Server error, which we will be discussed later in this section. Sometimes the disturbance is caused just because the File and Printer Sharing is disabled on your system. ![]() But in reality, it’s just a common network error. If you are a new user, you might take this error as a fatal one. 'The RPC server is unavailable' is a simple error that you may face while using Outlook or any other Windows service on a shared network.
