re: Time Service won't start - System Error 1290 Wednesday, August 4, 2010 at 6:43 am Windows 7 Annoyances Discussion Forum Posted by MartinM (7538 messages posted) The service is named Windows Time: I wonder if there's a conflict with Atomic Clock Sync v3.0 ? You could try uninstalling that to see if it is the culprit. It would also be helpful to know if the Windows Time service will start in Safe Mode ? As for re-registering the dll, you do have to unregister it first if the change is to be effective, and the denial of access is likely due to you not using full adminstrator privilege. Open a Command Window and type Run as administrator. You may be asked for a password. Then, as I think you know, run the following: net stop w32time w32tm /unregister w32tm /register net start w32time Written in response to: Time Service won't start - System Error 1290 (spection: Wednesday, August 4, 2010 at 1:42 am) Responses to this message: re: Time Service won't start - System Error 1290 (spection: Tuesday, August 10, 2010 at 2:50 am) All messages in this thread [show all] Time Service won't start - System Error 1290 (spection: Wed, Aug 4, 2010, 1:42 am) re: Time Service won't start - System Error 1290 (David: Wed, Aug 4, 2010, 6:08 am) re: Time Service won't start - System Error 1290 (Spection: Thu, Aug 5, 2010, 1:21 am) re: Time Service won't start - System Error 1290 (MartinM: Wed, Aug 4, 2010, 6:43 am) re: Time Service won't start - System Error 1290 (spection: Tue, Aug 10, 2010, 2:50 am) re: Time Service won't start - System Error 1290 (MartinM: Tue, Aug 10, 2010, 11:13 am) Reply or follow-up to this message Search this forum Start a new thread on a different subject Report abuse of the forum Return to the Windows 7 Discussion Forum
