Have you ever encountered the error with the message: “The RPC server is unavailable”? Though a common error, most of the users are unaware of what it is and how to correct it. RPC is a term that stands for Remote Procedure Call. It acts as a link between the system and the server.
“The RPC server is unavailable” error is shown when the computer fails to link up with the server. Several causes can lead to this error such as virus attack, firewalls, proxy settings and registry faults.
Once your computer shows the error, make sure that the firewall setting is turned off as some firewalls can prevent communication between the computer and the server. Moreover, the link can also be broken by the anti-virus security installed in the. Just disable the security installation and see if it brings a change.
Another thing that has to be taken note is whether the DCOM tunneling is enabled. To enable the DCOM tunneling, go to Start and then Run. Write DCOMCNFG and then click on the Component Services. From the component services, go to My Computer and choose Properties. After this, turn to Default Properties tab and then Enable DCOM. Once you have done this, scroll down to Tunneling TCP/IP and click the “Move Up” button and bring it to the top of the list. Once you have done all this, restart the computer and you see that “The RPC server is unavailable” error is solved.
One more cause of this RPC error is related to the registry. The registry is a place where all valuable data is stored. The error can show up if the registry has unnecessary files or if some of the files are corrupt. Clean the registry for the smooth functioning of the system. You can do the cleaning if you know how to do it or take the help of a technician. However, the best way to clean registry is using a registry cleaning tool. The professional cleaning registry is said to be the best option as it does the cleaning in the most effective way, without deleting any important data.
