Windows Update fails for some workstations behind TMG when using WPAD

“This post is about a recent scenario where TMG Administrator was receiving complains that some workstations that were using TMG as proxy were failing to run Windows Update. The interesting part of this issue was that only some workstations were having such problem and only if they were using “Automatic Detection” settings (which use WPAD). But all other workstations were using the same setting and were working just fine. “
