When I try to logon to my windows 7 64bit stand alone machine, I get the error message "the RPC server is unavailable"
It accepts the login - says welcome to windows then the error message waits a while then reboots. It has a fingerprint reader, but gives the same error when using a password. It will not start go any further then this in "safe mode" or "last know good configuration mode" or any other mode.. Did a checkdisk booting from a cd rom. Booting from a CD rom, I can see all of the files..
HP dv9000 4 gig ram
Stand alone - no Domain or homegroup
Windows 7 Ultimate installed since it was released
fingerprint reader installed, but I get the same error using a password
up to date on service packs, MS Defender, AVG (free ver), Malware (free ver), Spybot (free ver)
Hoping to not have to do a re-install
thanks in advance...
Another solution is to make sure "DHCP Client" and "RPC Endpoint Mapper" "Remote Procedure Call (RPC) Locator" "Remote Procedure Call (RPC)" are all running and set to automatic.
I hope this helps too.
Okay I've got a SOLUTION!!! :D IT"S FIXED
I uninstalled Office Beta 2010 this morning and when restarted the RPC Service unavailable yadda yadda couldn't log in
Okay F8>Repair>Run CMD then Bring up regedit>File>Export (Just get the explorer open)
What I've noticed is that this "repair" state is in the virtual "X Drive" so any changes made to Registry doesn't really affect the REGEDIT of your normal System when it boots
Okay now Navigate to your System Drive (REMEMBER THAT THIS REGEDIT CMD etc. IN THE REPAIR STATE IS ALL ON A VIRTUAL X:\ DRIVE SO GET INTO YOUR NORMAL SYSTEM DRIVE)
C:\Windows\system32\config (usually C:\)
Rename the File "SYSTEM" to "SYSTEM2" or similar. (These files are your registry hive files)
There's a folder called "Regback" which seems to be regular backups of your registry, copy the "system" from there into the "config" folder
Restart and YOU ARE DONE :D:D:D *happy*
Okay im not such a techy "coding" user and all that and if it wasn't for u guys I wouldn't have gotten it fixed (I didn't know what to do at first so i fiddled with wat u guys said) The n00B got it fixed in 1 morning though :D:D:D:D
Thanks a million guys and I hope this helps u
Thanks for the reply.. I did most of this already..
The only thing that was changed in the past month, besides updates, was the removal of Office 2010 Beta. I used the Microsoft uninstall tool to do that. I did that at least 5 days before this happened. I had not got around to put the release version on. However that was several days before this error started to occur.
I tried a startup repair from both the hard drive and from booting from the origional DVD several times.
all tests return Error code = 0x0 (which I believe means all OK)
Root cause found:
Boot status indicates that the OS booted OK
I tried to do a system restore booting from the hard disk as well as the origional DVD
at all restore points, it begins, then stops with the following error:
The instruction at 0xfb83584d referenced memory at 0x00000008. The memory could not be read.
the instruction at 0xfb8b584d, changes for example 0xfb19584d where the 5th 6th 7th and 8th characters vary by restore point. I tried every one.
The 0x00000008 I believe is pointing to the registry. Is this correct ?
I can not log in with any user account. It does the same thing. It validates and says "Welcome".. with the spinning thingey, then a big red X saying "The RPC server is unavailable" followed by a reboot.
I had the administrator and guest account disabled, I enabled them via a PE boot disk and blanked out all of the passwords, the do the same, appear to validate and say welcome, and the RPC error again.
Each boot, the initial user gets the RPC error
After the initial RPC error, if you use the same logon, or switch users the error is immediate "Windows Security The system cannot log you on"
I ran the Windows Memory Diagnostic Tool both from the hard drive as well as from the origional DVD as well as from the HP BIOS. all tested good
The HP BIOS is up to date
I ran avast! bart with the only errors being cookies and such.
I ran chkdsk c: /f from a command prompt booting on the origional DVD. all was normal.
I can get to the whole hard drive structure from a PE boot disk or the origional DVD and run regedit, or replace a .dll or ??? I just do not know what to look for in the registry or what to replace !
Norton AV (yes I have Norton Ghost on here without making an image in months) came up blank.
any other suggestions or what to look for in the registry before I just wipe it all ? All help is and would be appreciated.
Thanks in advance...
Again thank you for your attempt to resolve my problem.
You are correct in your first statement. The same issue persists even when you start the computer in safe mode. So the kb article is not relevent as I can not get to a GUI nor command prompt logged it to start/stop services via the GUI or the command prompt.
I dont believe the router on the system is of issue (there is no modem on the notebook). I have restarted the router, and most of the things I have tried I have tried with both the built in NIC on and off, the wireless g/n on and off, and all combinations of the NIC cards as well as a differant router at home and my work. This is a notebook NOT in a domain. It is just set as the default "workgroup" and is not a member of a homegroup either.
Any thoughts on my registry theory. where is the registry place and value to autostart this service ? I have been able to get by not using this laptop, but toward the end of Sunmmer, I am in education, I am just going to back up the data and blow it away an start over..
Thanks in advance ....
Sorry about misunderstanding your post. If you had created a system image backup, then use the backup file to restore the entire PC.

I appreciate your attempts to resolve my problem, with all due respect, am I dealing with a "bot" ?
How does one un-install or change a program, if one can not get past the logon screen either in safemode, GUI or commandline ?
The past two responses require a successful logon to implement. I have built, managed, and also teach helpdesk/system support at the college level. This question went way past reading a script answer after the first response. Please read the entire problem description and what has been tried, then jump to the level of the person that you are helping. It is acknowleged that I can not log in even in safe mode, then responded to with that limitation/requirement in mind.
I acknowledge that multiple security software programs can cause a system to fail. The ones listed, AVG (free ver), Malwarebytes (free ver), and Spybot Search and Destroy (free ver) do very differant things. MS defender has no documentated issues with any of the others. The free versions of Malwarebytes, and Spybot, require manual intervention. That said, I do know where in the registry to halt the startup of these progams in boot. Preventing them from starting and renaming their directories (so they are not in the correct path) effectivly should make it as if they are not running or installed (with the exception of a possible error with the system searching for them). Disabling them in this manner makes no difference. The error still occurs.
Can anyone answer my question that I keep coming back to. Where in the registry do I find, and turn on the RPC server service, what files need to be in the system and where, and what other dependencies does this service involve or require ??
Thanks again in advance...
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:
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...
