the RPC server is unavailable on windows 7 stand alone logon

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...

Just so you know, If you changed your computer's name and you were able to send fax before that, you need to add a new account so the fax software can get the ACCOUNT name. Windows is still not smart enough to do such a simple thing!

Hi guys!

Amazing how, more than 2 years later, I still used this solution to fix the problem!

In my personal case I had to use CMD to rename and replace the registry hive files.

If anyone needs to try I leave the steps.

Start SYSTEM REPAIR by pressing F8 at boot.

After language and other options chosen, SELECT Command Line Interface

At Command Prompt do these steps:

(you should be at X:\ drive)

c: (enter)

cd windows\system32\config (enter)

ren system system32 (enter)

cd Regback (enter)

copy system c:\windows\system32\config (enter)

restart machine

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

 

i am facing the exact same problem as you, exept mine wont give me any more acsesse at all besides the login screen, when i type my password it says"RPC Server not avalible" and when i press the on-screen shut down button, it just changes my picture to a flower? if you get ANY good responses that could help, email me at ******@gmail.com

Thanks! Your simple solution works! Windows 7 Home Premium is again working fine now!
