Common Errors and Problems when Activating Windows Vista with KMS Server

»»»Common Errors and Problems when Activating Windows Vista with KMS Server
Windows Vista Business edition and Windows Vista Enterprise edition can be activated by using a corporate KMS (Key Management Service) server, without contact or communicate with Microsoft. When you try to validate Windows Vista (Business or Enterprise) with KMS server, there are a few common problems and error messages that users may encountered. This article will provide some explanation and resolution or workaround to fix the errors for the following few error codes and descriptions.

Error” 0x80070005 Access is denied: the requested action requires elevated privileges.

Cause: Permissions issue as you don’t have enough privileges to execute the process or command.

Solution: Run as administrator.

If you’re not log on to Windows Vista as administrator user account, or your administrator account has been disabled, try the following steps to enable the administrator account again:

  1. Right click on Computer, then click on Manage, and then click Local Users and Groups, and finally select Users.
  2. Right click on Administrator account, and select Properties.
  3. Uncheck (untick or unselect) the check mark in front of Account is Disabled.
  4. Right click on the user account you currently used and logged on with, the select Properties.
  5. Select (tick or check) the option of Account is Disabled.
  6. Click OK.

0xC004F039 The computer could not be activated. The Key Management Service could not be reached.

Cause: KMS server is down, or Windows Vista unable to contact and reach the KMS server due to network issue, or been blocked access by firewall, or on wrong port.

Resolution: Try later, or try to disable your KMS firewall, or change to the correct port used for activation by specified :xxxx after the KMS server name (xxxx been port number).

Error 0x800706BA occurred in connecting to server -skms.
Error description: The RPC server is unavailable.

Reason: Possible due to incorrect product key or volume license key been entered, or didn’t input any product license key when installing Windows Vista.

Resolution: Click on Start menu, right click on Command Prompt, and select “Run as Admin”. Then issue the following command in Command Prompt:

cscript C:\windows\system32\slmgr.vbs -ipk YFKBB-PQJJV-G996G-VWGXY-2V3X8

If it’s still having the problem, try to reinstall Windows Vista, and key in YFKBB-PQJJV-G996G-VWGXY-2V3X8 as product key.


Reason: Permissions and privileges issues.

Workaround: Right click on Command Prompt (cmd) and select Run as Admin.

0xC004F038 The computer could not be activated. The returned count from your Key Management Service is insufficient.

Cause: KMS service needs at least 25 clients to be able to start the activation process.

Solution: Use more Windows Vista client to activate against the KMS server, or use crack or patch the KMS server as if there is always at least 25 clients.

    I tried EVERYTHING. I still have the RPC server problem. Despite the fact that I installed Vista using the Serial given (YFKBB…) the -ipk command doesnt work anyway. What do I have to do?

  • sonic

    If you do the -skms command with the ip adress, look carefully if you enter the ip of the vmware vista, I entered the ip adress of the pc where the vmware was running on a couple of times until i got it…

    Easy to make mistake… maybe a hint….

    Hi, and thanks for the promising Vista KMS Server.
    I too have the RPC server problem.
    I checked that the Firewall from real Vista was disabled, and tried the Bridged, Host and Nat .vmx files without success. Please, tell me if there is a workaround to effectively connect Vista to the KMS Server through VMWare.

    Ok guys, it's been a few days I am googling the earth to activate my copy, and thus I am proud to bring you this info :

    – A few of us have had the rpc error because of the "EU" origin of the VISTA DVD. The install. should not contain any "N" Versions (you know, "N" for no thank you, no memory hungry WMP 11 for me). Don't waste your time trying to activate "EU" Vistas through KMS Servers.

    – You don't need to power off the firewall to connect to the KMS Host. Allow TCP port 1688 both in your router and in your firewall. No need to sacrifice SO MUCH on security settings. (antivirus was up, too)

    – Another cool tip : You can safely bypass the IP copy/paste step. The slmgr command (poorly documented) support host names, so simply type the name of the KMS Host.

    – I didn't input a Product Key during install., but my guess is the result would have been the same with the key.

    To me, the "Small" KMS Server is a fine evolution, no chinese speaking forums to browse through, no .vmx file to edit in notepad…

    Thanks to members and thanks to the MS dev. teams 🙂
    These tips are for educational purposes, you should buy a Licence if you plan to use Vista in a pro. environment.

    Got a 0x800706ba + rpc server not available error…

    Tried this
    cscript C:windowssystem32slmgr.vbs -ipk YFKBB-PQJJV-G996G-VWGXY-2V3X8
    didn't help

    and yes, I installed vista with that key.

    Anyone an idea?

    There is another cause of the 0×800706ba error. Microsoft Word!! If you type up your doco in MS Word and share it, Word is notorious for automatically replacing dashes with an em dash, a different ascii character which doesn't work. so if your running a command like:

    slmgr –skms mykmsserver:1688

    Make sure you're not pasting it from doco. Just spent 30 minutes trying to troubleshoot this issue with a coworker, only to find out this was the case.
