Greetings from the TMG development team,
We are pleased to announce that with the Threat Management Gateway (TMG) RC release, we will complete the development of the dynamic GAPA Engine Update and the completion of the first batch of network protocols as part of the Forefront Network Inspection System (NIS) - the signature based component of the Forefront TMG Intrusion Prevention System.
Please make sure to upgrade your TMG Beta 3 (or earlier) deployments to TMG RC release, when it becomes available (soon). As of TMG RC release, Network Inspection System (NIS) signatures updates including Dynamic Engine Update will be available through Microsoft Update only for TMG RC builds and up. NIS signature updates to earlier beta versions will no longer be supported once RC is released.
