Mac user can't login to Windows domain

Had a quick question this afternoon from someone who had setup a Mac in a Windows domain environment. After setting up and joining the domain they had no problem logging onto the Mac with their Windows username and password. However, seemingly at random they were suddenly unable to login anymore.

It turned out to be quite a simple solution to the problem; the clock on the Mac was out of sync with the Windows domain controller. The Mac was running six minutes faster than it's Windows colleagues. Once the time was corrected the user was able to login to the Mac again with their Windows login.

Outlook 2010 cannot verify licence

I was reimaging a faulty computer today with a working Ghost image I had made some time back when I encountered an error opening Word. Every time I tried to open any of the Microsoft Office 2010 applications I got this error message:

"Microsoft Office cannot verify the license for this product. You should repair the Office program by using Control Panel."

After a bit of searching I discovered the answer was quite a simple one. The problem was that I had created the image some time back and the activation grace period had expired. In order to get Office to activate properly I needed to rearm the activation period.

To do this you need to open a command prompt with elevated administrator rights and type in the following command:

C:\Program Files\Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform\ospprearm.exe

This resets the 30 day grace period and you are once again able to open and activate Microsoft Office.
