I tried to creat manualy the computer on computer folder but did not work.

Unplug it from the network and let him login using his cached credentials. Then rename the computer and rejoin it to AD.

For the future, if your AD Domain Level is set to Windows 2008, then you can enable a Recycle bin for your AD.
This would mean any object you delete in AD will be moved to the recycle bin and can be restored from there very easily after an accidental deletion.
(Note: The recycle bin, once activated, can not be deactivated again)

See this article for more info:

Oh yeah, In case the cached credential login does not work, there will also be a local Administrator account. If you do not have the credentials for it, you can use a readily available password restore Boot CD, Boot from it and activate the Administrator account in case if is not already, plus you can reset the password if needed.

After you are back in the machine, you can simply add it to a Workgroup (with any temporary name) then without a reboot join it back into the domain, after which you will have to reboot and will be able to log back in using the AD Credentials.

Using the Workgroup Trick, will mean you can keep the same Server name as you will not need to rename it for this.
