Unified Aaccess Gateway 2010 introduced a new trace mechanism that is based on Event Tracing for Windows (ETW); a high-performance, low overhead, scalable tracing mechanism that is provided by the Windows operating system. UAG tracing provides detailed failure and debugging information in a binary format. This binary information can be converted into a readable text format using UAG trace symbols. UAG tracing symbols are now available on Download Center (<a href=”http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=fc052e67-2a04-4058-b326-9d92aa67b2c4″>http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=fc052e67-2a04-4058-b326-9d92aa67b2c4</a>). Forefront UAG tracing can be run on the both UAG server, and on client endpoint devices connecting to Forefront UAG resources.
