The RPC Server Is Unavailable. Attention. Before you read this tutorial, I highly recommend you check out my resources page for access to the tools and services I use to not only maintain my system but also fix all my computer errors, by clicking here! Before you can fully understand the function(s) of the RPC server, you will first need to know what an RPC is, such as its attributes and importance. RPC is an abbreviation of the words Remote Procedure Call.

It’s basically a technology that utilises a communication technique called inter- processing, which is used for enabling a server and client PC to communication with one another over a network. The basis of this protocol is the client/server model, which means data is packaged and distributed through this communication technology to other processes that do not exist on the same process (computer). The way in which it works is pretty simple: a procedure call is made, by a client computer; this call appears as though it was made locally, but is in fact made by a remote computer. During this process, the data for the call is then encrypted and sent to the server.

It is then decrypted and run by the server. A return value is then passed back to the client PC, which is determined by the initial data type that was sent to the server. This concept of compartmentalising network operations into procedure calls is a concept that was invented way back in the 1.

Make sure that no third party firewalls are blocking the needed ports. Third party firewalls that are known to cause this problem in the default configuration are. Introduction. Remote Procedure Call (RPC) is an inter-process communication technique to allow client and server software to communicate on a network.

Xerox being the very first machine to utilise this technology under the UNIX operating system. RPC technology is most important for those individuals that would like to share access to a printer over a network or manage computers within a network remotely. IT Support professionals are also known to use RPC services for managing computers remotely. To do this, they use the Remote Desktop feature on Windows. Any process which involves the distribution and sharing of data usually uses this technology. With that said one of the main drawbacks of RPC technology is that remote calls are known to regularly exhibit intermittent performance, and for a plethora of reasons; leaving you none the wiser when it does occur. Common Causes of This Error.

The RPC server requires a few services to be running in the background in order for it to function. If you’ve received “The RPC Server Is Unavailable” message then it’s likely due to maybe one or two services that the RPC server depends on for it its functionality, not working/running or it could be the result of file corruption. Alternatively, the unavailable message you’re receiving could be due to registry corruption or all three, in which case you would be required to do quite a lot of troubleshooting to solve the issue. Anyway, with that said, the most common causes are as follows. RPC related services have stopped running.

File and printer sharing has been disabled. A network connectivity issue. Registry data required for the RPC service has become corrupted. Given the circumstances, the best you could ever hope for is the issue being due to your inability to properly configure both processes to communication with one another. There are a number of items that you have to ensure are properly configured when attempting to use the RPC service, which means there’s equally as much troubleshooting to do when attempting to solve an issue with this service.

In the past, there were a plethora of malware and viruses floating around the internet that were designed to exploit your system through the security holes that resulted from using the RPC service. However, today, RPC is significantly safer, owing to all the proceeding security updates.

Automated Solution. Issues with the RPC service can be the result of a number of things. The cause of the issue varies depending on the specifications and configuration of your computer(s). This makes it increasingly difficult for you to pinpoint the exact cause of the problem. In addition, attempting to fix the problem manually can be a momentous task for most people, and in some cases, dangerous, if you’re a novice computer user.

Fortunately, there are a number of automated tools that you can use, such as Speedy. PC Pro. Speedy. PC Pro is a multifaceted registry cleaner program, which is capable of defragging your systems hard drive, speeding up your internet connection and freeing up hard drive space by removing unwanted clutter, cleaning the Windows registry and tackling issues such as the one you’re currently bogged down with, amongst others.

It’s recommended that you at least try the automated approach before attempting to fix it manually. With that said, to follow is a step- by- step guide that you can use to hopefully fix this problem. In this guide I will take you through a number of steps that will identify common causes for this error and provide recommended solutions for rectifying it. The steps are arranged in order of priority, which means you should start from the top and work your way down. Check Your Firewall.

If you have a third party firewall program on your computer, then there is a good chance that it could be blocking RPC requests. Thus, you will need to go through your firewall program and ensure that it’s been configured to allow outgoing and ingoing connections and that any applications that you intend to use with this service is set to trusted.

If you’re unable to reconfigure your firewall program, then you could consider turning the firewall program off, temporarily, that way you can find out whether it truly is the firewall causing the problem, when you reattempt an outgoing procedure call. Alternatively, if you’re using Windows Firewall, then you should make sure an Exception for Remote Desktop has been made and is enabled. To do this, simply do the following. First, ensure you’ve logged into your computer with administrative rights. Then click on Start - > Control Panel. Once Control Panel loads up, double click on Security Center.

Once Windows Security Center loads up, click on Windows Firewall. The applet for Windows Firewall should pop up, from here, click on the Exceptions Tab, then check the box next to Remote Desktop and click on OK.

Note: The Remote Desktop Exception is created by default; all you need to do is ensure it’s enabled and if not, enable it. Run Windows Update. I talk about this quite a lot when it comes to fixing a whole plethora or computer issues. Before attempting any other solution(s), it’s very important that your computer has all the latest updates installed on it. To check for the latest updates, simple go to Microsoft’s Windows Update site here: http: //windowsupdate.

Check Internet Protocols. The first thing you’ll want to do is ensure that the special drivers are installed properly, as they are used for internetworking.

The likelihood of you having problems with the drivers is fairly low, but it doesn’t hurt for you to check. This can be done by doing the following. First, ensure you’ve logged into your computers with a user profile that has administrative rights. Then click on Start, right click on My Network Place and select Properties. This will bring up Network Connections, from here, right click on Local Area Connection and select Properties.

The Local Area Connection Properties applet will load up. From here you’ll want to ensure that under this connection uses the following items: you have Internet Protocol (TCP/IP) and File and Printer Sharing for Microsoft Networks.

Note: If either one of these items is missing, then you will need to reinstall them. For information on how to reinstall new items, check out my post on how to fix the Winsock errors. Verify Your Drivers.

After you have verified that you have all the appropriate items installed in your internet connection, the next thing you’ll want to do is ensure that they are all working correctly. This can be done by doing the following. First, ensure you’ve logged into your computer with administrative rights.

Troubleshooting performance issues with Exchange when RPC request spike high « MSExchange. Guru. com. So you got a call from help- desk stating they have a lot of users complaining they cannot access their mailbox or performance is terribly slow? Ok, What next? I blogged onthe background process involved where exchange processes transactions and commit to the database. Let’s take a look at troubleshooting this issue. Once you ensure all mailbox stores are mounted, the next step would be to do this.

Start — Run — Perfmon. You see in the figure: RPC requests –> Clients are requesting for data. RPC Operations/sec –> Server is acknowledging the client request. Let’s look at how exchange prepares itself to handle client requests.

Microsoft Exchange Information Store service (store. RPC threads is allocated to the service upon registering with the RPC service. Clients connect and disconnect to individual RPC threads as they perform operations from their outlook like reading and sending e- mail, creating appointments and tasks, and viewing calendars. The MSExchange. IS\RPC Requests performance counter indicates how many threads are currently in use (“owned” by clients). The MSExchange. IS\RPC Operations/sec performance counter reflects the number of operations the server received in the past second. If the number of RPC requests increases steadily over time, it is a clear indication that the server cannot process client operations quickly enough. When the MSExchange.

IS\RPC Requests performance counter reaches 5. RPC threads have been exhausted, and clients will be unable to submit new requests to the server until all operations on an existing thread have been completed and that thread is released. Right now, you are facing an issue mentioned in step.

How to troubleshoot? I am listing down the various conditions the 2 counters will be and what they mean. MSExchange. IS\RPC Requests and MSExchange. IS\RPC Operations/sec are either low or at zero. Bottleneck might not be on the server. Something external to the server is preventing information from reaching the server.

Review Active Directory performance, network performance, client configuration etc. Get information about the GC the server is talking to using the NLTest command: nltest /SC. On an Exchange server, apart from the Store. CPU no matter what.

Verify that the system drive (usually C Drive) has atleast 2- 5. GB free space. Decrease the number of users on the server. See if online defrag is getting completed on all database’s. Believe me, it plays a huge role when the DB is too large and has a lot of whitespace in it.

The best way to identify this is to check eventvwr for events related to Online defragmentation like 7. Run Ex. Mon to see if it is a specific user is a top talker. In Ex. Mon, you can again sort client requests by RPC requests. MSExchange. IS\RPC Requests is steadily increasing but MSExchange.

IS\RPC Operations/sec steadily decreases. Exchange server is the source of the bottleneck. Verify that the system drive (usually C Drive) has atleast 2- 5. GB free space. Open task manager and look at “All processes”. On an Exchange server, apart from the Store. CPU no matter what.

Might be caused as something is preventing the Information Store from completing RPC operations, and the associated RPC threads remain allocated permanently. Wrestlemania 28 Invincible Song Download. More and more threads are allocated; the server has fewer available threads for new operations, so the number of new operations decreases. If the server eventually reaches 5. RPC requests, new RPC operations will be refused.

This is generally caused by either a serious physical resource shortage (memory or disk) or a processing issue within the Information Store or an integrated component (antivirus, journaling, and so on). Run Ex. Mon to see if it is a specific user is a top talker. In Ex. Mon, you can again sort client requests by RPC requests. See if online defrag is getting completed on all database’s. Believe me, it plays a huge role when the DB is too large and has a lot of whitespace in it. The best way to identify this is to check eventvwr for events related to Online defragmentation like 7. If Ex. Mon shows you high RPC requests from one user mailbox, open his mailbox and look for corruption in calendar.

Sort the calendar items by “list” and then by “size”. Any calendar item which is more than 8- 1.

MB is not considered as a “calendar” item. Delete it and notify the organizer that you had to delete it since the item got corrupted. Additionally, look for messages stuck in Outbox for that user.

There might be a zip file sitting and looping again and again. Use this: Get- Mailbox - Result.
