Solutions for Windows Time Service (W32Time) Problems

Atomic Clock Sync features the capability to repair the Windows Time Service in by stopping, unregistering, registering and restarting the service.

Unfortunately, there is a potential problem that has been confirmed by Microsoft for users with Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008. When you attempt to start the time service, some users will receive an error claiming the service could not be started. There are a few errors that all seem to end up with a similar solution:

Message 1

Windows could not start the Windows Time Service on Local Computer.

Error 1290: The service start failed since one or more services in the same process have an incompatible service SID type setting. A service with restricted service SID type can only coexist in the same process with other services with a restricted SID type. If the service SID type for this service was just configured, the hosting process must be restarted in order to start this service.

Message 2

The Windows Time service failed to start due to the following error:

The service start failed since one or more services in the same process have an incompatible service SID type setting. A service with restricted service SID type can only coexist in the same process with other services with a restricted SID type. If the service SID type for this service was just configured, the hosting process must be restarted in order to start this service.

Message 3

Error 1079: The account specified for this service is different from the account specified for other services running in the same process

Solution

Using Atomic Clock Sync, unregister and re-register the Time Service.

When you unregister the W32Time service, Microsoft clears all the current registry values guiding the sync process. When you re-register the W32Time Service, Microsoft sets everything back to their default values. One of these default values sets the system account used to run the service to "Local Service". The problem is that this Local Service account also needs an appropriate password to run.

Click Start, type "Services.msc" in the Search programs and files box, and then press ENTER.

(Alternatively, go to your Control Panel, launch Administrative Tools, then launch Services.)

Find the Windows Time service on the list and double-click to edit the properties.

Go to the tab at the top for Log On.

"This account" should be selected, NOT Local System account.

The text box next to "This account:" should say Local Service.

In the Password and Confirm Password boxes, delete all of the mask bullets to make each of these boxes completely empty.

Click Apply, then OK.

Try to start the Windows Time service again, either from the services program where you just edited the Log On properties or by using Atomic Clock Sync.
