What does Timed Out Trying To Establish A Connection mean in ColdFusion?
After a ColdFusion service restart or server reboot, a trusted-connection SQL Server DSN can fail to reconnect while other datasources (Oracle, for example) on the same instance work fine — the DSN's cached connection state doesn't refresh cleanly through the restart. Deleting and recreating the exact same DSN definition is often the only thing that clears it.

Deleting and recreating the exact same DSN definition is often the only thing that clears it.
If a specific DSN starts timing out only after a restart, delete and recreate it rather than just re-verifying, and confirm it's using ColdFusion's built-in driver (macromedia.jdbc.MacromediaDriver) rather than a third-party JDBC jar that may not reinitialize the same way.
