This is the second posting for this issue. I can't download and update my Windows updates. Each time I try I get the error code: 80072F78, which after I Googled the code apparently means that my computer's time and date are wrong. I checked and the time and zone are correct. However, whenever I try to sync the time with the Internet, e.g., "" or any of the other available options, I get a message "An error occurred when Windows was synchronizing with .... The peer is unresolved." Is this problem not allowing me to update Windows? I also Googled this and discovered that "" has been broken before. Any ideas on this? Thanks in advance.

In Control Panel, double click on Date and Time, click on Internet Time, then on Change Settings button. In next window select different server from drop-down menu (I use Click on Update now button. OK your way out. Restart computer.

Broni, I tried synchonizing all of the five listed and got the error message on every one.

Something is blocking the access. You need to check your firewall and other protection software to see if they may be blocking this action.
Also have you turned OFF any services and or the UAC?

DaveA and Rollin' Rog, how can I determine if I've turned off any services or the UAC? I ran services.msc and Windows Time services is running and set to automatic start-up. I did download and run "Vista Firewall Control" but last night I uninstalled this program and the same thing happened, i.e., I couldn't synchronize my computer's time and couldn't update Windows.

If you open the Security Center it will tell you if UAC is on or off. But I don't see what that has to do with it personally. I leave mine off.

Is there a particular onset to this problem? The "reliabilty index" graph in Performance Tools and Information > Advanced is good to consult for dates and issues.

Has it ever worked?

Are you seeing any other errors in the Event Viewer that might be related?

I don't know of any other services that would be relevant.

You see those time addresses in Broni's Post? If you open a command prompt (start > run: cmd) and enter



Do you get a successful 4 packet response from any of them? fails for me, but the rest work.

Rollin' Rog,

1. Windows Update has worked previously. I don't know what I might have done or what has caused it to stop but I think it has something to do with the time not being able to be synchronized with the Inernet.

2. I only got a sucessful 4-packet response on

3. Where can I see the "Relibility Index" and the "Event Viewer?"

Finally can you review the following HiJack This log? Thanks.

And you can't get a successful time sync with selected?

I don't see anything wrong with the scanlog.

You can access the Reliability Monitor by opening the Control Panel > Performance Information and Tools > Advanced page.

You can probably open the Event Viewer from there or just run eventvwr.msc

Rollin' Rog, sorry it has taken me such a long time to answer your post, but I've been away from my computer for a couple of weeks. This inability to be able to download and install windows upgrades has got me concerned. Right now I have eight critical updates that won't download. I looked at the reliability monitor but didn't see anything wrong which is not a big surprise because I'm not sure what I was looking for. Also, I don't understand why my computer's clock will not synchronize with the Internet? Also, all of a sudden, windows defender won't download updates. I turn this off since I have my own anti spyware program but still it's concerning. You have any other ideas as to why the clock won't synchronize and the updates won't download? Thanks again.
Dec 9, 2000
I think if you can set the time manually there should not be a problem with Windows Update -- but I could be wrong.

Are you connected through a router? And if so, can you test with a direct connection to the modem?

There is an alternative to Windows update -- you might want to give it a try -- it will identify needed updates and give you the opportunity to download them manually.

We may need to take a better look at this:

O20 - AppInit_DLLs: interceptor.dll,c:\progra~1\google\google~2\goec62~1.dll c:\progra~1\google\google~2\goec62~1.dll,wbsys.dll

intercptor.dll should be legitimately associated with "spycatcher"

Is this, or was this installed?

wbsys.dll belongs to WindowBlinds. Is it currently installed?

Sep 11, 2003
Rollin' Rog, once again, thanks for the help.

1. I think the time is set OK but maybe it needs to be synchronized to an Internet time hub?

2. I don't have a router;

3. I went to the Microsoft site: and was able to download and install everything but Vista SP1. (For that one, the site sent me to the Windows Update page which doesn't work.)

4. I once (I believe) installed and used something called "Spycatcher" but that was on an older machine. Maybe this program (or part of it) was brought to this Vista machine when I transferred files from the older machine to this one, or maybe Spycatcher "piggybacked" a ride with another program? Anyway, Spycatcher shouldn't be here; and,

5. I had WindowBlinds on the other XP machine but not this one.

Windows Update worked previously.

Do you know anything about System Mechanic? I recently started using this program which appears to have sped my computer up a lot. I thought this program might be the culprit re: Windows Updates and uninstalled it this morning but after doing this, Updates still didn't work so I reinstalled System Mechanic. Once again, thanks for the help.
Dec 9, 2000
Well frankly I rarely if ever use those types of programs, but they do have their uses -- I just can't evaluate any personally.

We can clean the registry of those orphan entires, won't help with the time sync though; I just don't know what's wrong there if Windows Time Service is running in services, there is no firewall, and your time is set manually to be reasonably close to the actual time.

Generally speaking "" seems to be the most reliable choice.

I'm not sure you should be in a hurry to install SP1 -- but if you have a really good download connection you could download the full setup.

Once it is installed, if you choose to do so, be prepared to reinstall some device drivers like Audio -- which have caused many people to lose sound after the update. I actually uninstalled it due to a couple of problems, including that -- but will probably reinstall in a day or two.

Now the orphan appinit entries.

Run regedit and navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\\AppInit_DLLs

Double click the "appInit_Dlls" value in the right pane.

In the "Value Data" field make it read:

c:\progra~1\google\google~2\goec62~1.dll c:\progra~1\google\google~2\goec62~1.dll,

(in other words, just remove the first and last dlls, but leave a comma at the end)

Close the box to save the changes and exit the registry editor.

Rollin' Rog, thanks again for your reply. I went into "regedit" and corrected that line. Regarding the time synchronization, because I'm living in South Korea I thought this might have something to do with the problem. So, I looked up different different time synchronization sites on the web and chose a couple from South Korea and Japan. I tried these that they didn't work either. I'm pretty sure that the problem with Windows Update stems from the computers' inability to synchronize with Internet time. The error number that I get, 80072F78, indicates that Windows won't update because of a problem with time and date. What do you think of the AVG antivirus program? I thought maybe my computer has a virus but I've run the AVG program twice and it came up with nothing. Thanks again for the help.
Dec 9, 2000
Have a look here -- there are some things specific to Windows Update that we haven't looked at:

Well I've been using AVG for years, but really I don't even need that, personally. Frankly, however, AVG is not the most thorough tool for virus checking.

You could try some of the online scanners; Kaspersky is considered very good -- but it won't remove anything.

Let me compare your W32time registry key with mine.

Run regedit and navigate to >


Highlight it, then select File > Export (give it a name)

Under "Save as type" make sure "txt" (TEXT) file is selected.

Then save the key somewhere convenient and upload it here as an attachment.
