Are you having problems installing Microsoft updates KB979906 and KB979909? If you’re getting this error message:
Installation Failure: Windows failed to install the following update with error 0×80070643: Microsoft .NET Framework 1.1 SP1 Security Update for Windows 2000 and Windows XP (KB979906).
Luckily, the fix is easy. The problem turns out to be an issue with VBScript, not the patch itself. If you go to the CMD prompt and run:
This will re-register the DLL and now, when you go back to install the patch, it will work perfectly.
Hope that helps…

So, it was bound to happen… We removed the wrong user’s mailbox in Exchange Server 2007 today. Unfortunately, with Server 2007, removing an account, removes the Windows user object and also marks the mailbox in the database for removal. Luckily, there is a relatively quick fix:
- Restore the Active Directory object with the AdRestore utility
- Connect the disconnected mailbox to the restored user account
First, we downloaded the AdRestore program from Microsoft onto our primary Active Directory server and then ran the command:
> adrestore -r username
The program searches through recently deleted (tombstoned) objects and allows you to recover them. The username part works as a rudimentary search. If it finds the object, it prompts you to proceed. Once you do, the account is restored. It’s disabled and doesn’t have a password, so you’ll need to set the password and the activate the account. Microsoft has a long drawn-out article on restoring Active Directory accounts, but running this simple tool seemed to work fine for us.
In the Exchange Management Console, we went to Recipient Configuration -> Disconnected Mailbox and went to find the deleted mailbox. Oh crap! It wasn’t there! Luckily, it turns out that if the mailbox management process has not yet run, you will not see recently deleted mailboxes. Fortunately, you can force this by going to the Exchange Management Shell and running:
> clean-mailboxdatabase “Mailbox Database“
After running this command, the disconnected mailbox now appeared. You then right-click on it, and select “Connect…” Check “User Mailbox” and click Next. Then, select “Existing User,” browse to find the user, make sure their Alias is correct, and click Next. Clicking Finish reconnects the user’s old mailbox to the restored user account.
The reconnection looked like it finished quickly, but we found that it took about an hour for it to fully connect and allow the user access to her email again. Hope this helped!
