Computer names over 15 bytes.

I am trying to join a computer to the domain, its name is AAAAAAAAAAAAAAABB

I get this message when I try to join it to the domain. I believe this is netbios limitation, but I noticed the computer doesn't get joined to the domain either maybe because there is another computer in AD with the same 15 first characters AAAAAAAAAAAAAAA

the netios name of the computer is limited to 15 bytes.The netbiosname
willbe shortened to "AAAAAAAAAAAAAAA"

Any help?

Ok I realized it created the computer account in AD but just with first 15 characters.
in the propertied of the computer object that get created in AD it shows the additional 2 characters in the DNS name field.
There is another field in the prperties of the computer account that says:Computer name(pre windows 2000) and it shows the computer name but just with the first 15 characters. how can I change it in AD to show more than 15 characters of the computer name
