I'm getting event id 4002.  Message says "WLAN AutoConfig Service has failed
to Start."  Error Code 2147746132.  Second event ID 7023.  Message says "The
WLAN AutoConfig service terminated with the following error:  Class not

I'm not able to connect to any wireless network due to this service not
starting.  Any suggestion on what may be the problem and how to fix it?

I am getting the same thing after installing the newest Zune 2.1
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,, 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 system
cannot find the path specified.). By using process monitor, I found
that it was looking for a folder C:\Windows\L2Schemas\.

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

I found if the content of these files is corrupted, then the service
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 of
the content is also important according to the microsoft technet
