I went to Active Direcotry Users and Computers today and do not see any computer accounts in the OUs that I am sure have some.

I have worked on the same 2008r2 network for over 2 years now. Today I opened up ADUC and browsed over to the COMPUTERS OU, expecting to see workstations I recently added to the domain. I was ready to move them to their proper OU and the OU was empty! I browsed to the normal OUs that we keep our workstations and laptops and they are empty too! However, if I do a FIND an for Computers, I can located individual names that I know exist. What could have changed? Did I put myself into a mode that will not allow me to see COMPUTER AD accounts? I am a domain admin and have been using ADUC since the Windows 2000 era. I need some advice as to what could have happened
