Google.

Years ago, I was on a project in England synchronizing the databases of various mail systems. We encountered an undecipherable error message from a Lotus Domino server. None of us techies could figure it out.The customer had a full support contract with IBM Lotus and they were not able to help.

Finally, one of the team members who was probably the least technical of all of us opened up a Google search window and typed in the error message. Voila! The solution! Google was in its infancy in those days and I had never heard of it.

Even now, before I go to the official sites to research issues with Microsoft, SAP, or other software products, I will do a Google search.
