When TMG is engaged in the process of validating, ashServ.exe (the Standard Shield, apparently) goes nuts on the CPU usage, as shown in Windows Task Manager. This freezes TMG in process, or at least slows it to the point of molasses. One by one I paused the 'providers', until finally pausing the standard shield freed up the CPU, and TMG practically flew through its remaining file validation.
Can anyone offer some insight into why these two programs might be problematic in concert? I'm not that comfortable with dropping shields to do TMG work since I'm on a wireless DSL modem that's always connected.
