    software. and not finding much out there about fixing it either :(.

    I started having this problem after installing Zune 2.1 as well. I didn't
    mention it in my first post because I wasn't sure if that's really the cause.
    Now that you and I are having the same issue, I think its no coincident.
    Normally the fix for this type of error is to re-register the dll for the
    service but I couldn't find any reference to it. I ended up using the
    original Vista CD that I installed my notebook with and "upgraded" itself
    again. Essentially, its a repair of the system file and registry keys and
    leaving third party programs and files untouched. I did also ran this,
    http://remove-it.org/tools/unzoone, before the "upgrade".

    I'm going to try the same thing when I get home this evening (usually
    carry my DVD in my bag, but took all that stuff out last week, lol).
    I figured the repair install would fix it though. Have you reinstall
    the Zune 2.1 software after the 'upgrade'? Also, did you initially
    have problems upgrading the Zune software before you had problems with
    the wlan? My firewall was turned off, so the install kept failing at
    100%, so I removed the old zune software, rebooted, reinstalled the
    new software, and that's when I noticed I was having wlan problems...

    After the "upgrade", zune 2.1 installed perfectly. I pretty much went
    through the same thing you did. WLAN was working fine before the Zune
    upgrade. Everything hit the fan after 2.1 install failed. I tried the Zune
    package that the error screen linked but the xml patch in the package is
    what's not installing. I too noticed I have no wireless connection after
    rebooting the PC.

    I had the exact same error (Error code 3 - path not found - The syste
    cannot find the path specified.). By using process monitor, I foun
    that it was looking for a folder C:\Windows\L2Schemas\.

    This did not exist on my install. By creating this folder (with th
    correct access rights) and then getting the files that are require
    (WLAN_profile_v1.xsd etc - these are the Zero config Wireless la
    config files ) from another install fixed the problem.

    I found if the content of these files is corrupted, then the servic
    starts to fail with all sorts of errors e.g. 2147500037, 2148270086
    depending on the actual file contents - i.e valid XML etc. The order o
    the content is also important according to the microsoft techne
