Change domain netbios name

Hi,

We have a domain setup (example: TEMP.com) and the netbios domain name was set to (example: TEM&P) when the domain was first created (NT 4.0 days). Many of our new applications have a problem interpetting the "&" in the netbios name. Is there a way we can change just the domain netbios name or get rid of the "&" from the netbios domain name? Our AD controllers are running Windows 2003 server. We also have a Exchange 2007 server as well as a few Windows 2008 R2 servers on our network.

Thanks

Zak
