Case 1: How To Troubleshoot RPC Server Unavailable – Error Code 0x800706ba

The cause

1. RPC server unavailable arise when RPC ports between servers are blocked, these are the ports that are involved in the server or communication process. RPC is the X11 protocol and is within the port range of 6001-6032. In the case of RPC error code 0x800706ba, 6007 is blocked and that’s why there is a problem.
2. RPC service has stopped from the remote server.
3. Endpoint mapper that’s on port 135 can’t be accessed by remote server.

RPC Server Unavailable

First fix of RPC server unavailable

1. First you need to test the RPC connectivity of the server you’re working on by using another server/computer.
2. This can be done by using this command; Get-WmiObject Win32_ComputerSystem –ComputerName OTHERSERVER
3. If there is a problem, you’ll see the output message in red, showing that there is a problem and if the test is positive the message appears in white showing details of the test result.
4. You can also run a test on a specific port, and in this Error Code 0x800706ba, port 6007 is affected. If everything is OK, a blank screen will show, and if telnet failed, it means the port is closed and a message that reads something like; ‘could not open connection to the host on port 6007 | connect failed’
5. If the results are negative, you need check windows firewall to ensure that RPC isn’t blocked, not only firewall, check also your antivirus software. Firewall and antivirus software are the common cause of RPC ports. So check your settings and give permissions to RPC, the problem will be solved. To make things easier, you should disable windows firewall to see if the RPC ports are now working without the error display. This is a quick way to find whether it’s from firewall settings or not.  If things are ok, it means you need to adjust firewall settings to accept RPC ports. You should also disable any firewall service that’s on the server so that you know if it’s firewall problem.

Here is how to configure windows firewall to accept incoming-remote management connections;

• Open msc (Group Policy Object Editor), this should be used to change group policy object that’s used to manage firewall settings.
• Go to Computer Configuration > Administration Templates > Network > Network Connections > Windows Firewall.
• Next is to open the profile you want to configure, either profile or default domain profile.
• You should enable these two options; ‘Allow exception for remote administration’, and ‘allow exception for file and printer sharing’.

Second Fix: Change DCOM Access Group

The Error Code 0x800706ba can arise if the computer is a member of DCOM access group or wrong authorization is given. Here is how to deal with this problem;

1. Check controller domain where the certification service is granted.
2. Check to make sure these group of domains are available; Certificate Service DCOM Access or CERTSVC_DCOM_ACCESS. Under any of these two groups that are available, you should add this domain groups; Domain controllers, domain users and domain computers.
3. Update DCOM-security-settings on the server with CA role using these command;

certutil -setreg SetupStatus -SETUP_DCOM_SECURITY_UPDATED_FLAG

net stop certsvc & net start certsvc

4. Check the COM security permissions on the server that has the CA, remote access & remote activation permissions should now be allowed to the group you’ve created.
5. Restart your computer to see if the certificate has been issued.
