I want to change all my computers who I have bought in year 2003 and I want to know how many I have...



Mart,

He wants to know when a machine was bought... If he is using an up-to-date CMDB he can find it by a simple query...

If he don't have one the BIOS date is probably the best option. Or you have to know which type of processors are manufactured in 2003...
