Microsoft Azure ADSync doesn't start

New Contributor

Dear all,


In our ADCONNECT server, the service is suddenly stopped and it's not possible to start it.

Our synchronization between onpremise & Azure is stopped.

Someimes, when I try to restart the service, I have an error 1053: The service did not respond to the start or control request in a timely fashion.


Any idea?

Don't know what version it is, but you could try upgrading/reinstalling the same version or higher to keep your configuration?
Yeah a repair - or if it an AD Connect V1, then upgrade to V2 -

Version 1.* of Azure AD Connect goes out of support this year, as it relies on an old version of SQL that won't be supported.'

You could try to increase the timeout threshold temporarily as a test - - to see if the service actually starts after a few minutes, but I would use the opportunity to upgrade it to the latest version, especially V2 if it was previously a V1 release..
