Try this simple technique to write messages that help users understand the reason for errors.
The first time a user encounters an application's documentation, it's not always with the user manual or online help. Often, that first encounter with documentation is an error message.
Technical writers should be involved in writing error messages. It's an important, although often overlooked, part of the job. After all, error messages are documentation, albeit documentation that's embedded in the code.
[...] An error message should be meaningful. By that, I mean full of meaning not only for a developer, but also for the user of the software. To prevent any panic or confusion, the message should be clear.
A meaningful error message should:
- be short (you can write in sentence fragments);
- contain a description, in plain language, of what went wrong; and
- use wording or a tone that doesn't (whether explicitly or not) blame the user.

"Unknown user/password combination" - it states just that, the combination is unknown (also covers missinng password database)
"Unable to log in" - short and sweet, implies computer is at fault (append "please try again" to coax the user into trying again while still implying the fault is computerside)
"Credentials not accepted" - implies that something failed (apply "please try again" if needed)
"Credentials not accepted by system" - same as above put alludes system at fault.
"Unable to synchronize, please retry" - same as above.
Or my favorite: "Didn't work! Try again?"
