There are a number of ways to access the SQL Server errorlog:
- It's on disk, the location could be C:\Program Files\Microsoft SQL Server\MSSQLnn.WINCCPLUSMIG2014\MSSQL\DATA\LOG. ERRORLOG is the current log, but the crash dump would be in any of the older one like ERRORLOG.1, ERRORLOG.2 etc.
- You can run xp_readerrorlog from a query window in SSMS. With no parameters, you get the current errorlog. Specify 1 to get the most previous log and so on.
- You can access them from Object Explorer under Management->SQL Server Logs.
The complete crash dumps are in the LOG folder, but they are mainly of interest to a support engineer.
If it did not start despite the server being in Delayed Start, possibly it crashed immediately, but then for some reason started successfully manually. You should be able to determine this by looking at the the starting dates for the log files.
