Problems with EFS Configuration in GPOs?

No Comments »

Having issues similar to:

Trying to enable EFS on a specific OU, while it’s disable at the top of the structure or domain?
Recovery certificates from two different GPOs mixing up instead of being replaced?

Overall EFS GPOs looking like they aren’t merging properly?

Well, it’s not because EFS GPOs are supposed to behave like black magic. Turns out there’s a bug, Microsoft’s aware of it, but doesn’t think it would be a good idea to FIX IT on Windows XP and 2003.

Thankfully, all it means is you need to edit your GPOs from a Vista, 2008 or Windows 7 machine.

KB : EFS may not be enabled expectedly after you disable a policy and this policy turn off the EFS feature

Opening my EFS GPOs in Windows 7, switching the Allow/Don’t allow and applying the ‘change’ fixed my GPOs. A few minutes later, and stuff was behaving like it should’ve been… Can I have those wasted hours of my life back, Mr. Ballmer?


0xC0000225 Error trying to install Windows 2008 R2 (Or other x64 Windows)

57 Comments »

As I was attempting to play with Windows 2008 R2, which only comes in 64bit flavors, I received this error when trying to start the setup:

nothing useful nothing useful nothing useful 0xC0000225 blah blah blah blah blah

This was on the latest version of VirtualBox, on a 32bit host. At first I thought it was a bug in VirtualBox, since it didn’t support 64bit guests on 32bit hosts for so long, but it turns out that when I enabled IO APIC for that Virtual machine, everything worked fine !

Happy testing.


WSUS 3 Error – WARNING: WU client failed Searching for update with error 0x8024400e

You might have had some computers not communicating properly with your WSUS servers.

After looking at the WindowsUpdate.log file, you notice an error, WARNING: WU client failed Searching for update with error 0x8024400e .

You then find info about
1) This error being related to Office 2003 Service Pack 1, and that unapproving it fixes the isse
2) Microsoft having released a patch for this issue that you can install on your servers.

But in reality, the issue might be…
3) You’re retarded, and called a computer group on your test lab .. Group! .. With the ! !


Performance impact of clearing your swap file at shutdown

No Comments »

For security reasons, it might be advisable to clear your swap file at shutdown.

It doesn’t provide great security, and you really should be using full drive encryption anways.

But in case anyone is wondering, for a 1.5gig swap file, this option (ClearPageFileAtShutdown) seems to add about 30 to 40 seconds of time to the shutdown procedure as it overwrites the file with zeroes.

Now turn it back off and install Truecrypt!


TS: Windows 7 , Configuring – 71-680 (Beta of 70-680)

No Comments »

I got a voucher for the Windows 7 exam a few weeks ago , so I had signed up for today..

 

I barely had the time to install the release candidate, so there’s a bunch of features I was not familiar with, but there was still some stuff that wasn’t Windows 7 specific. In any case, if you follow the guide, you should end up fine.

In any case, I’ll know if I passed in about 8 weeks, which should take us close to the middle of July.

 

Good luck to everyone trying it out.
