I have been having problems with the time service on my windows 2008 server from day one. Now I am getting: System error 1290 has occurred. 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. This occured after I changed the service to Local System instead of Local Service. It complained that it wasn't allowed to run as Local System. So I unregistered the dll and registered. The setting was restored to Local Service, but now I am getting this error message and am hesitant to just blindly reboot. I have looked for other articles on this and they claim to adjust the tapisrv image path from tapisrv to NetworkService. If I was on a client machine I would do it, but this is the Operation Master server for everything. I tried to restart most services, but it still didn't help. Thank you for any assistance you can offer.

Hi, Windows Time service is running in a shared service process, known as svchost. There is a group of services sharing the same SvcHost process as the Windows Time service and the services must run under the same credential -- Local Service, by default. As a result, the service may not be able to start after you change the logon credential. In this case, please ensure that all services in the same service group as Windows Time service are running under the same credential. The following is the list of the services for your reference: lltdsvc NSI SSDPSRV upnphost SCardSvr w32time EventSystem RemoteRegistry WinHttpAutoProxySvc lanmanworkstation TBS SLUINotify THREADORDER fdrespub SstpSvc netprofm fdphost WebClient Hope it helps.

Hi, I have a similar problem to that described in this thread. I have a Windows 2008 Server computer that is a PDC for itself and one other computer. I would like to sync this PDC to an external NTP time source (from pool.ntp.org). I have tried to setup w32time, but I have not been able to get w32tm to start. It is reporting the same 1290 error that GoBlonda was seeing. How do I investigate the other services to find the one(s) with the non-matching login credentials that are preventing w32tm from starting? Thanks!

I am having the same problem. I carefully went through the whole list of processes above, and all of them are set to run as Local Service. However, not all of them are running. I am not sure if that is a problem. Any further help would be appreciated. Regards, Harold NaparstHarold Naparst
