Certain Windows updates will not download on any PC on our network

Hi,
We've had a problem that seemed to develop a couple of months ago in that certain Windows updates will not download to any PC on our network, most notably IE11 and .NET 3.5.1 updates. Most others will download and install with no problem at all.
I have tried running the Windows Update Fixit, I have tried deleting the /Windows/SoftwareDistribution folder, I have tried the System Update Readiness Tool, I have added the various Windows Update server URLs to our firewall whitelist, I have
tried a clean boot, but to no avail. Downloading and installing the affected KB patches manually works fine though.
When I connect any of our PCs directly to an external router the updates download and install fine. It's only when connected to our network (which comprises a Peplink WAN load balancer, Cyberoam CR25iNG security device, Windows 2003 domain controller
& Arista 10Gig switch) that the problem exists.
Most updates download successfully but others only get to a certain percentage downloaded, most commonly 45%, although I'm not sure if that's a meaningful figure.
For example, the most recent batch of updates all download and install fine except for KB2982378, KB2894844, KB2972211 & KB2973112. Is there something those updates have in common that something on our network could be blocking?
I'm really unsure where to try looking next, so if anyone has any suggestions they would be very welcome please.
Thanks,
Matt

Hi Matt,
When you connect to an external router directly, does your network location change to private or still domain network?
I suspect this is related to some firewall setting, even related to your network security device.
Please check or upload the WindowsUpdate.log ( %windir%\Windowsupdate.log), we can find some information about downloading phase.

Newest update will not download

Newest update will not download. Every update except for the newest one has worked. Have windows vista.

There is an issue with the security certificate of Apple's download site which your browsers may have a tendency to block it.

HT201412 app updates will not download what is the solution ?

app updates will not download

I am having a similiar issue, but I am not getting any error messages. The App Store tells me I have updates. I go to update all, then they just hang in limbo.
The first app listed was Pages which I thought was causing the problem as it requires Mt. Lion and I don't have that yet. None of the other apps would update. I deleted Pages from the ipad and tried again. When I go to the App store from my MBP, it tells me there are no updates, so I can't even download them to the computer. The ipad still tells me I have updates. I click the "update all" button but now, only one app loads at a time and I must wait awhile and repeat the update all to have another one load. I have not experienced this at all since I've owned it - over a year. Any insight would be helpful - trying to avoid Restore if possible. Thank you-

New updates will not download??

new itunes update will not download even manually....any suggestions?

The app is a very small file. (A flashlight app for iphone)
Hope that helps.

My Officejet 4500 all in one cd will not download on a Windows 8 upgrade. Windows 8 sees the printer but not the scanner. HP web site support drivers do not make the scanner work either. What else can I do to make it detect the scanner?

Hi,
What is the model of your HP Officejet 4500, must be G510* where * can be from a to z.

ITunes will NOT download on any of my laptops nor computers. I've tried everything. Why wont it download!?

iTunes will not download no matter what i do.

If you've tried "everything" there is nothing left to do.
No one can help you if you choose to not provide any details of what happens when you try.

I have tried for 3 days to download Firefox..It will NOT download. Any ideas?

I have a life time membership, but I cannot download onto a new machine. It is using Windows 7..I had Firefox on my old machine and I have it on my home machine in another state..I am completely baffled as to why it will not download. Plenty of ram and plenty of memory on this new machine. HELP

Thank you but your suggestion did not work..
It appears to download then my System Suite Recovery Commander takes over and NO download...

Updates will not download

I gey update notices but they just loop and will not download, nor can I download at the itunes site.

One approach, if you haven't tried it would be to do a restore...then when putting your stuff back on after the restore, incrementally add the apps back in....

If that doesn't work, you could try dfu mode....I haven't tried this in iOS 6, but imagine it works the same...
DFU mode[1] is a state that you can put your iPhone into where it can interface with iTunes but does not load the iPhone operating system or boot loader (this is what really differs DFU mode from recovery mode). DFU stands for Device Firmware Update.
While connected to PC, running iTunes, hold down Home and Power( button on upper right edge) button for exactly 8 seconds.
Release the power button. Restore message will appear in iTunes. The device will be recognized by iTunes, but no display will appear on the device itself. The lack of a display on the device will verify that it is in dfu mode.

ITunes updates will not download. Problem began with iTunes 11.

iTunes will not download to my computer. No firewall or pop-up blocker issues. Started with iTunes 11. Have same problem on 3 different computers. Does anyone know anything about this? Please help!

It's possible the AppleTV is being seen as a streaming only library - are you able to view streamed content under My Movies etcor My Shared Movies etc?
If the content is new and is HD it's possible you're downloading 1080p which ATV1 can't handle or sync.

I'm experiencing the exact same problem on a 2008 R2 server we have overseas. I've reinstalled the WUA, uninstalled all updates that occurred in the last successful update push, uninstalled the antivirus, scanned for viruses, deleted the SWD folder,
uninstalled WSUS.
I've tried so many things from so many sites that I don't know what I've done and haven't. The funny thing is I can go into the registry and point it to get updates from our WSUS server onsite and it works, it just won't get them from Microsoft. Below

Windows Update will not install

Hi expert, recently I have restored the computer to the factory setting (windows 7 64 bits) since the virus destroyed my registry and I couldn't install the MSE. It seems everything is OK now.
But I have over 114 Windows updated files which cannot be installed. I tried updating the driver software from the device manager and trouble shoot following the Microsoft Fix link. Then I manually updated these files. It first installed service pack 1 and it seemed working, but it took forever to update one file. Then finally it finished and restarted the windows. But it took forever to shut down. Then I turned off the power. After I turned it on again, the system showed Windows 7 Service Pack 1: Failure Configuring Service Pack, reverting changes error and it went on and on without stop on the screen and never ended. I waited for a long time and finally the windows restarted and it showed it had 114 files to be updated and it looked like they were updating. But when the updates was finished, I turned on the machine, the 114 files were still there, not a single file was installed.
Before Windows 7, when I format my drives, I only insert the bootable disk to the CD drive and then everything will be installed from CD when the machine is turned on. But when I insert the CD into the CD drive and turn on the windows 7 this time, the CD will not boot at all. Does it mean windows 7 does not need to use the bootable disk? We just restore to the factory setting instead. Do I have to format the c dive first and then restore to the factory setting? Please advise! Thank you!

>Windows Cleanup seems to have done the trick, though before trying it I actually managed to install LR 2.0 beta with no problems. Anyway, since it's a windows system, anything can happen -- and frequently does!
But that is what happens; you may get an error trying to install one particular application while all others work perfectly well. The cleanup utility fixes the problems for that particular application and saves you doing registry edits etc.
>I have install issue saying I dont have the right Window Installer error when I install 1.4.1 update too.
If you do not have the "right Window Installer" you may need to download the latest version from Microsoft. You can find the revision of your current windows installer by looking of properties of Msiexec located in c:\windows\system32. My version is 3.1.4000.1823.
This is the link to the download:

Also, make sure that your Windows is up-to-date.
