When working with UAG, clients might run into various errors, but the error message that’s displayed to the user may not always clearly tie to the details of the problem. When a user reports a problem, the first step for the UAG administrator is to inspect UAG’s Web Monitor, which would list the full error message, with additional details. For example, the user may see a simple “You have attempted to access a restricted URL”, while the Web Monitor would show a more detailed “The URL is blocked by one or more Forefront UAG out-of-the-box rules for the application”. To make life simpler, here’s a full list of all the error messages UAG might show, with some more information about what they mean. Note that the full text won’t always give you a resolution, but it should point you in at least the general direction.
