Error: "RPC server Unavailable" at startup

Hello Brian,

Welcome to Microsoft Community Forum.

An RPC client is an application running on any given computer that uses the RPC protocol to communicate with an RPC server.

An RPC server is a communications interface provided by an application or service that allows remote clients to connect, pass commands, and transfer data using the RPC protocol.

Please reply to these questions, to understand the issue better:

1. What is the complete error message?

2. Are you using a 3rd party antivirus application on your computer?

3. Do you remember making any changes to the system prior to this issue?
 

I would suggest you to try the following methods:

Method 1:

I would suggest you to check if you are able to access the RPC (Remote Procedure Call) service and also make sure that the following services are started and the startup type should be set to Automatic.

If it is not started follow these steps:

a) Click Start, type “services.msc” (without quotes) in the start search box and press Enter.
b) In the Services window, find Remote Procedure Call and right click on it to select Properties.
c) Under the General tab make sure the Startup type is Automatic and the Service status says Started.

Repeat the steps b & c to f for the following services also:

DHCP Client, RPC Endpoint Mapper & Remote Procedure Call (RPC) Locator.

Method 2:

Step 1: Boot the computer in Safe mode and check if the issue persists.

Safe mode starts Windows with a limited set of files and drivers. Startup programs don't run in safe mode, and only the basic drivers needed to start Windows are installed.

Refer to the link below on instructions to get In Safe Mode.
http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7

Step 2: If the issue does not persists in Safe Mode then perform a clean boot to check if any third party application is causing the issue, as clean boot helps in eliminating software conflicts.

How to perform a clean boot in Windows: http://support.microsoft.com/kb/929135

Note: After troubleshooting, refer to this section ‘How to reset the computer to start normally after clean boot troubleshooting’.

Method 3:

If issue persists, I would suggest you to check if you face the same issue in different user account. You may create a new user account on your computer and then check.

Create a new user account-

If you do not face the same issue in a new user account then you may refer the below link and use the steps provided to fix a corrupted user profile -

Hope this information is helpful. Please do let us know if you need further assistance, we’ll be glad to assist you.

Thank you

The completer error code is "Exception EOLeSysError in module Skype.exe at 001251C9

The RPC server is unavailable"

Method 1.     All are  Automatic and the Service status says Started.

Method 2.     Laptop booted up ok in safe mode.  Step 2 laptop booted up ok in Clean boot

I haven't tried Method 3 yet as I am now wondering if it is something to do with Skype.

I'll wait you response

Hello Brian,

The RPC server is unavailable"

Hello,
 
Thank You for keeping us updated with the issue.
 

You may try creating a new user account and see if that helps. Please follow the link below to create a new user account.

To create a user account:
http://windows.microsoft.com/en-us/windows/create-user-account#create-user-account=windows-7

Also refer to:

 I  did create a new account that worked ok as a basic account. I then deleted it after proving that it worked.

Are you now saying that you want me to make it work as my current account?  with all the programs etc that I use now.

I have also been following this thread as i began having "RPC Error" appear 10 days ago upon login about 50-75% of each boot-up. The only error message right after entering the login is: "RPC Error: Server Unavailable." No other information or error code is visible.

When this happens, I'm not able to open and run Windows 7 except when i reboot in safe mode, but then, I have not been able to diagnose the issue in safe mode since "Services" does not run. 

I am not able to pinpoint any new applications or changes that may be causing this.

Clean boot did not change anything, like safe mode, resulting in a successful boot-up and login, but without critical capabilities. Adding a new user did not change anything--the RPC error code results after i try to login from every user with their correct credentials. I don't have Skype on the machine, so it's not that.

The machine is a refurbished HP8440 early generation i5 machine running Windows 7.

Any suggestions?
