I am currently troubleshooting our alerts system. It seems to send alert emails intermittently with sometimes no delays or sometimes multi-hour delays.

I am poking around in the log files and the only critical ones I see are

The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) for

Process: OWSTIMER.EXE EventID: 5586

I am trying to figure out what database setting it is actually trying to connect to ? I can't tell from the error message what db connection is failing.

  • You can run Set-SPLogLevel -TraceSeverity VerboseEx to capture which database it is connecting to, but this is indicative of overall network connectivity issues between SharePoint and the SQL Server.
