RPC Server Unavailable or RPC Server Not Responding In Windows XP and Windows Vista

What Is Remote Procedure Call?

The Remote Procedure Call (RPC) server is a service in Windows XP that is used to validate and start other services within the system. If the RPC server is unable to start the appropriate service, it might return an error stating that it is unavailable.This error occurs during the installation of printer related products because the RPC server cannot find the print spooler that is needed to install the product drivers. This will occur if the spooler is disabled or corrupted. It may also occur if another print driver is not permitting access to the print spooler.

For information on this issue and for steps on how to resolve the issue, I recommend you visit

Recently I encountered an error "RPC server not responding" is displayed while installing printer software. This error occurs if the Windows print spooler is not running

To resolve the issue, you need to:

1. Restart the RPC services.
2. Restart the Spooler services.

Restarting the RPC Services :-

Perform the following steps to restart the RPC services:

1.click start,settings,control panel,
2.Select Administrative tools.
3.Double-click Services.
4.Select Remote procedure Call.
5.Right-click "Remote procedure Call" and select start,if it is already started refresh it.

Restarting the Spooler services

Perform the following steps to restart the Spooler services:

NOTE: You will require Administrative rights to restart the print

1. Click Start and then Control Panel.
2. Depending on the View settings of your computer, open the Services

a. Double-click Administrative Tools.
b. Double-click Services.

3. Locate the Print Spooler entry.
4. Right-click the Print Spooler icon and then click Restart.
5. A progress message will be displayed.
6. Right-click "Print Spooler" and select "Properties".
In the General tab make sure that the startup type is set to Automatic. Click on the Start button of the Service Status is Stopped.
7. Click on the "Recovery" tab and change all 3 drop-down boxes to "Restart The Service".
8. Make sure the 2 text boxes underneath say "1" in them.
9. Select the 'Log on' Tab and make sure that the 'Local system Account' is selected and click Apply and OK.

After, the steps are completed, follow the below steps:

Click Start > RUN, the Run box will open.
Type: INF in the box and click OK.

In the INF folder, delete ntprint.pnf, printupg.pnf, infcache.1 and any oemXXXX.pnf (XXXX being a sequential number ex:oem2.PNF).
IMPORTANT: Delete only the .pnf, not the .inf - the .pnf is the cached version of the .inf and will be regenerated if it doesn't exist.

After the Print Spooler restarts, you should be able to print or you might need to completely uninstall the printerdriver

1. Click Start > Run and type in: services.msc
