Can't change the functional level

I work on a VMWare environment with one domain controller after I deleted a second one (delete from disk) and now I get “The functional level could not be raised. The error is: the directory service is busy” when I try to raise the functional level from windows 2000 to windows 2003. How would I do this?
Any help will be appreciated.

That's OK when you have more than one DC, in my case I only have one, used to have 2 but like I mentioned I delete from disk the second one.

Did you transfer all the roles to the one server that was left? if yes, you need to clean the AD metadata.

The following link explain the procedure to clean the metadata

When you run netdom query dc how many DCs you see. If only 1 then you need to  change the DNS settings and make current DC as authoritative time server and perform reboot. If there are 2 DCs then you need to run metadata cleanup, remove DNS records and delete container object from DS sites and services. Once everything is done run repadmin /kcc *.

Before removing second DC, do you check where FSMO roles are?

Could be happened remove DC has FSMO roles and functional level could not be raised.

On a domain controller command prompt type "ntdsutil" and press enter. Then, "roles" and enter, "connections" and enter. May you require on this point provide credentials (domain admin), please input them. Now, press "q" and enter, input "select operation target" and enter and "list roles for connected server" and enter. Now you get a list of roles and what server is his owner.
If any role is owned by deleted domain controller, you must to seize domain controller you have on line:
