Getting the RPC server is unavailable (0x800706ba) while connecting to the remote device, communicating between two or more devices through a network? The Remote Procedure Call (RPC) is a mechanism that allows Windows computer to communicate with one another, either between a client and server across a network or within a local network. And we can say RPC plays a vital role in managing devices remotely across a network and is used to share access to peripherals such as printers and scanners.
The Possible causes of the “RPC server unavailable” error may the RPC service on the server isn’t running, Errors resolving a DNS or NetBIOS name, Problems with network connectivity. Also, may a firewall or other security application on the server, or a network firewall appliance between the client and server may be preventing traffic from reaching the server and more.

If you do have antivirus software installed, temporarily disable it. And again try to reconnect to the client computer.
Also, use the ping command to test basic connectivity between the RPC client and server.
If the client and server are members of an Active Directory (AD) domain, DNS is used for name resolution. Verify that the client and server are both using the correct DNS servers, which must be inside the domain and will typically be domain controllers.
Open command prompt as administrator, type ipconfig /registerdns on the RPC server to re-register its DNS records.
Check RPC Service function properly
Sometimes “The RPC server is unavailable” problem can be caused by improper functioning of RPC service on every computer connected. We recommend to Check and make sure RPC related Services Running properly.
Press Windows + R, type services.msc and ok to open windows services console,
Scroll down, and look for Remote Procedure Call (RPC) service,
Right-click and select restart,
Now, again right-click Remote Procedure Call and select Properties.
Ensure its status is Running and their startup is set to Automatic.
Click apply and ok,
Do the same process for DCOM Server Process Launcher and RPC Endpoint Mapper service
Now connect to the remote device, check there is no more RPC server is unavailable (0x800706ba) error.
Configure the Firewall on your computer
As discussed before firewalls or any other security-related applications running on the system can block traffic from RPC requests. If you have a third-party firewall installed, try configuring it to allow incoming and outgoing connections for RPCs and other applications that you intend to use in RPCs. If you are using Windows Firewall configure it to allow incoming and outgoing connections for RPCs and other applications by following steps.
Open Control panel
Search for and select windows firewall,
Then click Allow an app through Windows Firewall below Windows Firewall.
Then Scroll down to find Remote Assistance.
Ensure its communication is enabled (All the boxes of this item are ticked).
Now ope group policy editor using gpedit.msc and click ok.
Here on local group policy editor Navigate to the following path.
Here on middle pane double click on start And change its value to 2.
Note:If there is any item that does not exist in the image below shows then we suggested to reinstall your Windows.
Again Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesDcomLaunch.
See if there is any item missing. If you found DCOM Server Process Launcher was not correctly set, double click on Start registry key to edit its value. Set its value data to 2.
Now Nevigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesRpcEptMapper. See if there is any item missing. If you previously found the setting of RPC Endpoint Mapperwas not correct, double click on Start registry key to edit its value. Again, set its value data to 2.
After that close Registry editor and Restart, windows to take effect the changes. Now on next start check and try to connect remote device.
Performa System Restore
Sometimes it is possible that you have tried all of the methods above, and you still get the “RPC server is unavailable” error. In this case, we suggest performing System Restore which reverts windows settings to previous working state, Where system Working without any RPC error.

One of the most commonly-seen, and seemingly-inexplicable, error message on Windows 10 machines is the dreaded “RPC Server is Unavailable” error. Although this error can cause great confusion to inexperienced Windows users, it is not a severe or serious error, it won’t usually cause you to lose any data or programs, and best of all, it’s relatively easy to fix. In this tutorial, I will show you how to resolve this error on your Windows 10 machine.
First, let’s talk about what RPC is in the first place to allay some of the confusion and mystery. RPC stands for “remote procedure call”, and it is a method that computers have used literally for decades to communicate with one another. What makes things a little confusing is that with modern PCs multitasking and running many programs at once, RPC has become a method that some applications use to communicate with other applications running on the same computer. RPC is basically just a system that allows different processes to communicate with each other to perform a task. It works a bit like networking in that the RPS server will open a port, communicate with the destination service or server, await a response, send a packet when it has a response, and then transfer the task data to the destination server or service. The whole process operates in reverse when the destination service or server has done its job and has data to send back to the initiating program.
The models are actually designed to fit into WEP's own post-apocalyptic game called 'This is Not a Test' which is a great little system. Ncr in fallout 4 release. As such I have based her force on this later game's extensive imagery for the faction.In New Vegas the Rangers seem to have three distinct sub-commands which are civilian rangers for urban police duties, elite veteran rangers for hardcore combat and patrol rangers that fall somewhere in the middle.I have already made a squad of veteran rangers and a squad of civilian rangers so all that remained for me to do was a squad of patrol rangers in order to balance out the force. However let's be honest.they're clearly heavily inspired by the NCR's elite troops.which can only be a good thing for my needs.The miniatures themselves are great and each of them has a lot of character especially in their faces! The Rangers first appeared as part of a side quest in Fallout 2 back in 1998 but they were substantially expanded on in in 2010's Fallout: New Vegas.
Although we are going to talk about RPCs in Windows systems in this article, you should be aware that the RPC methodology is used on just about every kind of computer system in use today. It’s a methodology, not a Windows-specific process. Most RPC server errors occur within one computer, but the cause of the problem can be something on that computer or something in the network as a whole. I’ll show you how to figure out both kinds of problems in this article.
RPC server unavailable errors
So what would cause an “RPC server unavailable” error? Well, let’s say that one service on your computer needs to communicate with another, so it contacts the RPC server on the computer to initiate the exchange. The RPC server uses ports on your computer to “listen” and “talk”, and it is the server that does the actual enabling communication between services, whether they are networked or local. If the call to the RPC server fails because the server is unavailable, does not respond, cannot write to memory, or cannot open a port, then the “RPC server is unavailable” error is triggered.
How to fix RPC server is unavailable errors
On a Windows 10 machine, there are three basic potential causes for this error message. Either the RPC service is not running, there are issues with the network, or some important registry entries that control the RPC service have been corrupted. In Windows 10, the most common cause for the error is that the RPC service is simply not running.
The first thing to try with any Windows error is a full reboot. If the RPC service stopped working owing to a temporary issue, then a reboot will restart it along with the rest of the computer, so this is the first thing to try. If a reboot doesn’t resolve the error, then try the following fixes. Note that these fixes are written specifically for Windows 10 computers, but the same general processes can be used on previous versions of Windows.
RPC Service
If a reboot doesn’t solve the problem, then the first thing to check is to see whether the RPC service is actually running.
Right click on the Windows Task Bar and select Task Manager.
Select the Services tab and then the Open Services link.
Navigate to the Remote Procedure Call service. Ensure it is running and set to Automatic.
Navigate to the DCOM Server Process Launcher. Ensure it is also running and set to Automatic.
If the two services are set to anything other than Automatic and Running, change them. Depending on your system permissions, you can also restart these services. If you have rebooted your computer already this won’t achieve anything as they will already have been restarted.
Network issues causing RPC server errors
Even if a particular RPC call might be operating completely internally on your computer, it still uses the network stack to communicate. That means that issues with TCP or your firewall can stop RPC from working.
Type ‘control’ into the Windows Search box and select Control Panel.
Select Network and Internet and Network and Sharing Center.
Select the Ethernet link in the center and then Properties in the popup box.
Ensure IPv6 and File and Printer Sharing for Microsoft Networks are both enabled.
If both IPv6 and File and Printer Sharing for Microsoft Networks already are checked, you’ll need to check the firewall.
If you use Windows Firewall, select it in Control Panel.
Find Remote Assistance and make sure it is enabled for Domain, Private and Public networks.
Save any changes if you made them.
If you use a third party firewall, you may have to experiment to enable this setting. You shouldn’t need to change anything if you have been using your firewall for a while but check just in case.
Registry errors causing RPC server errors
OK, so rebooting didn’t help, your RPC and DCOM services are running fine, and the network stack is chugging along. (You probably wouldn’t be reading this article if it wasn’t, anyway.) The last thing you can do is to check the registry entries that control the RCP and DCOM services to make sure they haven’t been corrupted. Messing around with the registry isn’t for the faint of heart but if you make a backup of it first, you can always undo anything you change. So let’s back the registry up first.
Type “regedit” into the search box.
Select Computer from the left side.
Go to File->Export.
At the Export Registry File dialog, type a name for the backup file and hit “Save”.
Now that you have a safe copy of your registry stowed away, you can check the entries for the RPC and DCOM services.
Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesRpcSs.
Select the Start key in the right pane and make sure the value is set to (2).
Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesDcomLaunch.
Select the Start key in the right pane and make sure the value is set to (2).
Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesRpcEptMapper.
Select the Start key in the right pane and make sure the value is set to (2).
If you have tried all these fixes and RPC server errors still appear, it’s time to restore from a restore point or refresh Windows. Just make sure to select the options that don’t overwrite your files and settings if you go for the refresh!

This error occurs when the “Distributed Transaction Coordinator” service is not running. To start a distributed transactions with TransactionScope object, the windows service “Distributed Transaction Coordinator” should be running.
To fix the problem just start the service “Distributed Transaction Coordinator” using Windows Service manager.
Here are the detailed steps for starting the service
Click on Start–>Control Panel->Administrative Tools->Services (or simply type services.msc in the run command box and hit enter); display “Services” manager
Scroll through the list and identify the service “Distributed Transaction Coordinator”
Right on the service and choose “Start”
