Windows guest won't update on Mac host, will on Windows

[iainc]

Hi,

I'm having a weird issue that's got me scratching my head.

I have an iMac running OS X 10.10.4 and VirtualBox 5.0.0 r101573. I've created a Windows 7 Pro x64 guest VM and everything is working fine except Windows Update.

The guest VM is configured with a bridged network adapter, it has a static IP address, it is a member of an Active Directory domain that has WSUS configured and all other machines work fine. The guest VM is able to communicate with the network without issue, browse the web and all the usual connectivity tests are good however when attempting to run Windows Update I get an unknown error 8024400B.

I assumed that this would be a problem with the Windows guest itself or the WSUS server it is trying to get it's updates from BUT I have eliminated those possibilities by simply copying the entire VM to a Windows host, firing it up and discovering that Windows Update now works. This must mean that there are a specific set of conditions when the guest is running on the Mac that cause the issue. I don't even know how this could be possible but it is what I'm seeing......

Has anyone else encountered this issue or do you have any suggestions of what I can try to resolve this?

Cheers,

Iain.

Even weirder, I updated the VM on the Windows host and then moved it back to the Mac host and now everything works! Very odd......

Just one possible cause, incorrectly set time can prevent Windows Update from working and this is not diagnosed in any kind of understandable way (affects VMs as well as physical hosts).

I have the same problem. I updated to 4.3.30 from 4.3.26 last week and now Windows 7 Pro says there's 14 critical updates available, but when I tell it to download and install - it just sits there. McAfee Security Suite does the same thing when I tell it to retrieve system updates. I've never had this issue before. Internet and network connections are fine. Any ideas?
