Error 0x80072f8f

[Guest]

Windows Defender was unable to complete the update: 0x80072f8f.

I am getting such problem when I am trying for updation. My Internet
connection run with a proxy setting 10.2.1.5 port 3128. There is no general
problem to access internet.

Having OS Windows XP with Service Pack 2.

Please help and suggest.

I have done as per your instruction. But till the problem persist.

I got the same error after installing Defender on a Win2000 SP4 machine.
Trying to do a windows update results in the same error - it had always
worked before. I've checked the date/time, uninstalled the signature file
and one other item MS recommended, but still no good. Since MS claims no
support for Defender I guess I should post the problem to Windows Update.

Here's something that may be worth trying--troubleshooting via WindowsUpdate
is definitely the right idea.

start, run, regsvr32 msxml3.dll

See whether that succeeds, and whether it changes the behavior.

I'm also having the same problem and have followed all suggestions listed to
no avail. Has anyone found a fix for this yet?

Do you also get this error if you go to Windows Update?

I tried: start, run, regsvr32 msxml3.dll
but got the following error message

dll registerserver in msxml3.dll failed
Return code was: 0x80070005

OK - I'm out of my depth now.

I think I'm going to recommend going with a canned WindowsUpdate fix.

Here's Microsoft's troubleshooting starting point:

In terms of third-party fixes:

Dial-a-fix is one:

A number of folks here swear by this one, and users are reporting good
results.

alternatively:

(but take a look at Microsoft's troubleshooter first--it probably includes
these steps)

http://www.daniweb.com/techtalkforums/showthread.php?p=152523

The set of steps in the start of this thread look likely to be both safe and
effective--but obviously not 100% because I believe this thread ends without
a fix for the particular user involved.

The computer was so badly infected with adware and viruses that I just
decided to format it and reload all software. Problem solved. Thanks!

 

[Guest]

I logged in as an administraror and redid the
start, run, regsvr32 msxml3.dll

This time it worked. Defender checked for updates and windows update had no
problems. Thanks a lot for the help.

 

[Bill Sanderson MVP]

Ah--thanks--probably should have said to be in as an administrator--and that
error code probably meant a permissions issue, which was one reading of it I
was finding. Thanks for letting me know.

Just be sure to be well firewalled while you reload all critical patches. I
just applied all updates to a neighbor's teenage daughters laptop today.
The machine is well specced, and wireless and bluetooth equipped--a latitude
D800--but their family rule was no Internet access with it until now--so it
was as delivered, on SP1, no antivirus, no antispyware. I started out
working in their kitchen in the evening using an open access point from
another neighbor, but that got old fast, so I brought it home. It wouldn't
connect wirelessly to my WPA/WPA2 protected AP until the updates were
completed, so I had to plug a wire in. Besides all the Windows Updates, I
added OneCare and Windows Defender. A large number of other installed apps
had updates as well--not all were security-related, but:

QuickTime
Flash/Shockwave
Ez cd creator
several DVD player apps.
A number of pieces of an Adobe suite she has student licences for from the
school
A piece of software to talk to a TI programmable calculator
Adobe Acrobat 6 (which required the cd, which I don't have)
Adobe Acrobat Reader (ditched acrobat 4, and reader 5, for reader 7)
Didn't put in Sun's Java.
Did update the system bios--the new version was, I think A13, the original
was A3, and I figured that might well be worth it.
Bluetooth driver software needed to be updated.

There've been a lot of changes in the world since SP1!
