How to swap computer name swap between 2 systems in AD?

Hi,

We have 2 systems ser1 ser2 which is in domain. We have 2 swap these 2 names. ie, assign name ser2 to ser1 and ser1 to ser2. Only option is the below or is there any easy method or tools to do this?
rename ser2 to ser3
rename ser1 to ser2
rename ser3 to ser1
This is what we normally do. any other suggestions? or tools which will do it fast?

Thanks,
Sarath
