Unable to start and stop services

[BarryTookey]

Two weeks ago I republished an existing map service with a schema change and everything worked fine.  Yesterday I attempted to republish that same map service and it published, but it won't start.  I've published new test services, and they will not start either.  In fact I've since discovered I'm also unable to stop any of my existing services.

On a side note...I keep getting this "Copying Data to Server".  It lists the two feature classes that have recently changed, including the feature class with the schema change that was successful two weeks ago.  I do not get that with any new test services that I publish without those two feature classes.  But again, they won't start.

Thanks for any assistance.

What is the source of your data (e.g. file geodatabase, SDE)?

It sounds like you might need to register the data store (i.e., your Oracle or SQL Server data connection or your file GDB) with ArcGIS Server before publishing.  If the data store(s) referenced by the layers in your map document / service definition are not registered with ArcGIS Server, I believe the default behavior is for a copy of the data to be made and placed locally on the ArcGIS Server machine.  To prevent this, check out the following link:

Is there any chance you are connecting to SDE with a different user after you made the schema change?  I ask because you register SDE connections (at least Oracle connections) with a specific user connection.  If you originally published a service with user1 where the SDE connection is registered with ArcGIS Server (AGS) and then you made some changes to the mxd which include a connection to SDE with user2 where the SDE connection is not registered with AGS, then the SDE will be automatically copied to the AGS server.
