I have a Windows 2012 R2 server which has been happily running a windows service for roughly 3-4 months with various build revisions going into the software.
The server configuration hasn't changed at all, however I have just started seeing the following error when manually trying to start the windows service and doing it from our build system.
System error 5 has occurred. starting service
The event log is pretty fruitless too:
The <service name> service terminated with the following error: Access is denied.
As mentioned above the accounts used for this have not changed. I have checked that the service folder has full permissions on it and have even tried running the service under a local account and administrator account. Both of these produce exactly the same error.
Is there any way for me to obtain more information about the problem? Nothing else on the server seems affected.
