Over the past few months Microsoft has released a number of “rollup” fix’s for TMG 2010 (see below).   They fix a wide range of issues which are shown in detail when selecting the links below.  If you have any issues with TMG read the articles below and see if the issue will be resolved before installing the updates.  I guess that all these updates will be part of TMG Service Pack 2 when it is released later this year.

Before you install the below fix’s you will need to Install TMG 2010 Service Pack 1 and TMG 2010 Service Pack 1 Update 1.
