Windows Update V6 through MS Proxy 2.0 - How I Eliminated 80072F78

After all of the posts that I read saying that the new version of Windows
Update (v.6) cannot authenticate through MS Proxy 2.0 and that the only
viable solution is through the use of WSUS, all I can say is
........"yeah...right!"

I have 5 Windows 2000 Professional Workstations accessing the internet
through MS Proxy 2.0 on a server that utilizes Panda Corporate Antivirus.
After upgrade of the workstations to V.6 of the Windows Update caused all of
the subsequent connections to the Update site to fail with an Error Code
0x80072F78. I read all of the posts and KBs regarding Proxy problems,
firewall problems, antivirus problems, etc. Here is what I did to correct
the problem.

First, I deleted all of the files and folders in the C:\WinNT\Software
Distribution Folder. In order to do this, I had to reboot the machine in
Safe Mode as deletion of these files in normal operating mode caused a
sharing violation - files in use error.

Second, after deleting the files and folders, I restarted the machine as I
normally would and connected to Windows Update. I was then able to scan the
system and Update forced me to re-download the latest version of Windows
Update - which I did. I then had to restart the machine as directed.

After the reinstallation of the new Windows Update, I noticed something
peculiar - my Winsock Proxy Client no longer had a valid server name
associated with it. I then re-installed the Winsock Proxy Client software
and restarted the machine as directed.

I then connected to the Windows Update site and was successfully able to
scan, view, download and install updates. After installing all of the
critical updates, I again executed Windows Update to verify that I was able
to reconnect to the site. It worked just fine! In fact, in lieu of Express
scan, I selected Custom scan just to verify that I could find and download a
driver update.

I hope this helps someone else fighting the 0x80072F78 error!

During the course of updating my five workstations, I found that one is
giving me problems with subsequent connections to the Update Site. Four of
the five machines initiated a reinstall the latest version of the Windows
Update software (V.6) after deleting the Software Distribution folder
discussed below. All of those machines will allow follow-up connections to
the Windows Update site (even after a full shutdown and reboot).

The Update Site did not want to reinstall the Windows Update software on the
one problem machine. I was able to connect to the Update Site one time but
not subsequent times. It appears that the success of my other four machines
was dependent upon reinstallation of the Windows Update software. I guess I
now have to figure out how to force reinstallation for that one machine and I
will be good to go. Any guidance or thoughts on that subject are appreciated!

Nice to hear you got your PCs updating again :-).

Here, we can't install the winproxy client on some PCs (e.g. the domain
controllers). We use MSP 2.0's web proxy feature to provide Internet
access. I've found that the only solution to the "80072F78" problem for
those systems was to add the "Everyone" group to the access control list for
the "WWW" protocol (see Web Proxy..Properties..Permissions).

Of course this isn't an ideal solution, as now MSP2.0 anonymizes every
outgoing connection (every connection in the web proxy log is listed as
"anonymous").

I've implemented WSUS here for our 160+ node LAN. Very nice package. Can
tell at a glance which machines are updated, which machines require updates,
and what updates are required. As I only used the web-based Windows Update
procedure for testing purposes, I can work my way around it, after grumbling
at Microsoft for implementing a Windows Update upgrade that doesn't work as
well as the older version.

Have a look at WSUS. It's useful, even if you only have 5 workstations to
look after :-).

Regards,
Brian Steele

BTW - stopping the wuauserv service before trying to delete the software
distribution folders should've taken care of the file access problem.

Brian,

Thanks for the response - as you probably realized, I posted in your earlier
thread about having similar problems as you did with Proxy 2.0. I don't
believe that I can effectively use WSUS - I am still running Small Business
Server 4.5 and looking at the minimum requirements for WSUS, I don't believe
that I meet them.

What is interesting - the only machine that I am still having problems with
is the machine that did not initiate a reinstall of Windows Update V.6 after
performing the procedure that I outlined in my first post. Remember - all 5
of my machines were upgraded to Windows Update V.6 and all 5 originally
refused to connect to Update with a 0x80072F78 error. After performing the
procedure in my first post, all but 1 of my machines reinstalled the Windows
Update V.6 and were able to repeatedly connect.

This makes me believe that something was modified within Windows Update V.6
from the time that I first installed it to the point where it was
reinstalled? It just doesn't make sense to me at all! Nothing within my
proxy settings or workstation Internet Explorer settings were changed on ANY
of the workstations.

Any insight that you might have regarding a forced uninstall of Windows
Update V.6 on my 1 remaining workstation is appreciated. Thanks.
