Sure, but you must reset the domain SID after you change the server name.

Before changing the server name:
	net getdomainsid

Stop winbind, smbd, nmbd.

Change the server name.

After changing the server name, and BEFORE starting nmbd, smbd, and winbind:
	net setdomainsid S-1-5-21-xxxxxxxxxx-xxxxxxx-xxxxxxxx
per the domain SID reported by 'net getdomainsid'
