Windows 7 Direct Access Connectivity Assistant reporting incorrectly RRS feed

  • Question

  • We can't be certain when this issue started, however we only noticed it yesterday when troubleshooting on a laptop.

    Client is Windows 7 Enterprise with the Direct Access Connectivity Assistant (DACA) installed.

    Starting from a power off situation we follow the following steps: 

    * boot laptop on LAN, login, verify everything working, DACA reports "Corporate connectivity is working" (DACA is happy)

    * undock laptop and wait for DA to kick in, verify everything working, DACA is happy

    * re-dock laptop to LAN, verify everything working, DACA is happy

    * undock laptop and wait for DA to kick in, verify everything working, DACA is happy

    * re-dock laptop to LAN, verify everything working (i.e. can access internal network, drive shares working) ... and ...

    after the 2nd re-dock, DACA reports "Corporate connectivity is NOT working" and despite the fact that everything is actually working, it stubbornly stays that way.

    If we shutdown the laptop and restart, it returns to normal behaviour again, until the 2nd re-dock and then the problem repeats.

  • I discovered the cause of the problem this morning.  It was due to a "cheap" gigabit switch which was in the network path when the notebook connected to the LAN. 

    When we cabled the notebook directly to our usual access switches, everything worked 100% reliable.  Through the extra cheap gigabit switch, failures returned.

    We replaced the cheap switch with an (old) Cisco 24-port switch and it worked fine.  We plugged the notebook through a VOIP phone (extra PC port) and it worked fine.  Back connected to the cheap gigabit switch, failing again.

    Happy to have found the cause.
