WSPAD file is in bad format

I’ve been configuring TMG auto client proxy detection and it was failing. After researching it online and internally, didn’t find anything useful.

So when I installed the TMG client and run this test:

C:\Program Files (x86)\Forefront TMG Client>FwcTool.exe testautodetect
FwcTool version 7.0.7734.100
Forefront TMG Client support tool

Action: Test the auto detection mechanism

Requesting wspad.dat file
Web server is connected and ready to send WSPAD file
Downloading WSPAD file

WSPAD file is in bad format
Failed to detect Forefront TMG
Result: The command failed and was not completed.

So in able to fix that, I’ve changed the SCP from wpad to wspad using adsiedit (or you can use the tmgadconfig tool again with –f switch)

Hope this helps!
