Hello rulirahmadi,

If you edit the registry and add another time server it works fine.
I just did it.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr  entVersion\DateTime\Server
Add a new string value
Name it 3
add the name of a time server as the data
use this list

Always be careful when editing the registry, you can stuff up your PC if you
change things you don't understand

You need to reset the windows time (NTP) settings back to defaults, here's how:

Open a command prompt (Start-->Run, type CMD.EXE, click OK)

Run the following commands to reset the windows time service to defaults:

net stop w32time
w32tm /unregister
w32tm /register
net time /
net start w32time

Here are a list of NIST time servers if you'd rather use a different one:

The registry settings are not cleaned up if the unregister fails.  
Try creating a new account that is a member of the "Administrators" group and running the w32tm /unregister and w32tm /register commands (and those that follow) again.

I have the same issue.  When I try to unregister the w32tm I also get the same error message as noted above.

I have tried to make another admin user account.  
I then logged out all other users.
Logged in with the new admin user
Then ran the above suggested solution, and it still generated the same error when trying to stop the service.

I found on Microsoft forum:

that we must type the "w32tm /unregister" twice. But, still no luck :(

Looks like we must another server to get it work properly...

Yes, did the w32tm /unregister twice anyway...well if at first you don't succeed punch buttons repeatedly philosophy :)

Also tried using different time servers, but still no luck.  Its not a major issue for me, but I just happened to find you with the same issue.  Thought I would drop in with the same problem to see if my problems in some way can help people find a good solution for you.

Check the permissions of the following registry key:


Make sure that administrators have full control of the key and all subkeys.

Checked and yes, Administrator and SYSTEM  have Full Control and Read in the Allow column.
Who is the group of CREATOR OWNER? This user have Special Permission (allowed).

I clicked Advanced button, point to Owner tab. I changed the owner from Administrator to my username (member of Administrator too). Still no luck...

Creator owner is a builtin system object.. It represents the user who created or is the current owner of the specified resource

I can sync my Vista with now!

I use TuneUp Utilities which will automatically added several server:

Because of I'm still can't sync my Windows with for the first time, then I try the added server one by one. My Windows can sync with them.

Last, I try with and it work.

But looks like I must use the additional server first before my Windows can sync with

Just trying to sync again (Vista) and failed with server. The 2nd server,, sucessfully. Back to server again and sucessfully too.

I thin we must make a provocation to server by using another server that works and the sync with server.

O.K., nothing has worked, yet.

    When I use w32tm /unregister, it always returns
w32Time successfully registered.
     It has never returned unregistered. I have repeated the command many times.
