the RPC server is unavailable on windows 7 stand alone logon

Well mine started after u used the office 2010 remover to uninstall office 2010 beta, and after restarting the machine i got this error message,, I also don't want to format my machine but looking at the way things are going .. I think i'll have to format it. II really need to use it for some work .. Luckily i have ubuntu on another partition so i've been able to backup my e-mails from Thunderbird.. I really wish there was another way of going around this problem apart from formatting!!!!

afoteygh ...  Mine was a clean install, with a full format, and has worked since the week of Win 7's release. It has been a couple of weeks, but I did uninstall Office 2010 beta, and had not got a chance to install the release version on that computer when it went south. It did however work for a few days, perhaps a week after the uninstall.  I used a Microsoft Utility I downloaded from MSDN/Technet to un-install Office 2010 beta and "clean"  the machine.  That might be the reason.. Can you boot safe mode or do a system restore ?? I can not get past the logon screen.. in any mode...  

I thought that we finally found the answer, as yesterday when I did the above instructions, I also had no RpcLocator in my registry entry. I was thinking it was a path issue that Windows 7 could not find the service to start. 

Per the instructions, the first key exists and has the right paramaters.

Booting for various PE disks, the RpcSs (net start RpcSs) is running already and the error still occures after re-boot.

I also did not see the registry key even existing for "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcLocator"

We have an almost Identical HP laptop, running 64 bit Professional instead of 64 bit Ultimate, the same model base, video, motherboard, and configuration. 

It does have the RpcLocator entry.

So looking at that registry, I copied the entry to use it in the other HP computer.

I looked at a couple of other computers and the entry for RpcLocator was the same.

Here is the entry I used/created:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RpcLocator]

"Description"="@%systemroot%\system32\Locator.exe,-3"

"DisplayName"="@%systemroot%\system32\Locator.exe,-2"

"ErrorControl"=dword:00000001

"FailureActions"=hex:84,03,00,00,00,00,00,00,00,00,00,00,03,00,00,00,14,00,00,\

  67,00,65,00,00,00,00,00

"Start"=dword:00000003

"Type"=dword:00000010

 The problem is, I can not get this entry to stick in the registry of the hosed computer.

I get it in there and it is gone upon reboot (to the broken computer) and the same error comes up.

I have used a WinRE environment from a retail version of Win7 as well as an MSDN version of Windows 7.

I have tried it with a Bart PE disk with a Linux registry editor.

We have a licensed copy of Active @boot disk which pays for the Microsoft PE environment and has a registry editor.   Didn't work/stick either

I have set permissions in all environments (booting from all the PE disks) to "everybody"

I set permissions in the registry also to "everybody"

I have exported/imported  the system hive as well as all the other hives and tried to get it to stick that way.

I even exported the entire registry, put it on a USB disk and edited it on a differant computer in a different environment.

I think I (we) are close. Something obviously messed with the  RpcLocator registry key..

My problem now is,  (and I STILL CAN NOT BOOT INTO THE MACHINE ITSELF) how to get that key into the registry of the broken computer and have it stick !

I could give up and just do a clean install, but I would really like to learn what happened and how to fix it..

    Thanks in advance...

I am having the same problem.. and it came about after i used the Microsoft Tool  to remove office 2010 beta unfortunatley i am not able to find Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcLocator  in my registry.. what do i do now??

Hi Turbo00,

Try the following steps and check the result.

Step 1: To start the RPC service, try these steps.

a. Start the computer using Windows DVD to boot to Windows Recovery Environment (WinRE) and select command prompt.

Note: Follow Step 1 in my first post to boot the computer to WinRE.

b. Type net start RpcSs and hit enter.

c. Type exit to close the command prompt.

d. Restart the computer and check the result.

Step 2: Check the registry entry for the service

a. Start the computer using Windows DVD to boot to Windows Recovery Environment (WinRE) and select command prompt.

Note: Follow Step 1 in my first post to boot the computer to WinRE.

b. On the command prompt, type regedit.exe and hit enter.

c. Look for the following entries:

i. Entry for Remote Procedure Call (RPC):

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcSs

ii. Entry for Remote Procedure Call (RPC) Locator:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcLocator

**Important:**Set REG_DWORD value to 2 for automatic start on RpcSs

Set REG_DWORD value to 3 for manual start on RPCLocator

Very important: Modifying the registry incorrectly will cause serious damage to the computer. Backup the registry before you make any changes.
