How to create a dns rule for my web page that will change the dns suffix.

I have a DNS network with a "veryverryverylong.local" domain name. This is fine for webmail because they only need their ad username. unfortunately for my web page my programmer needs the full name for user logon. users are stuck typing username@verylongdomainname.local. I was wondereing, is there a way I can configure DNS so that I can use username@differentshorterdomainname.local without changing the actual .local domain name? will i need to register this dns name for the logon to work outside of the lan? (i don't think so...., the active directory is 100% internal and works with the current .local domain name for logon) What about giving users alternate logon names for use with the website. All i know is I cannot change the domain name without killing the whole system and starting from scratch. (it's pretty complicated)

The only possible thing that could help is if IIS was handling the authentication, in which case you can set the default domain name as I described above, which will automatically populate the domain if just a username is entered.  

Otherwise, unfortunately, "No" is the answer to this question, and since you can't change a domain name on an SBS, it would require a full reinstallation to make it shorter.

It's not a DNS issue, but rather an Active Directory one.  Since SBS still supports NetBIOS, you can have them use SHORTERNAME\username for the login instead.  The NetBIOS name is truncated at 15 characters.

Also, if whatever web application you are having created uses forms based authentication, then you don't need to enter the domain name at all when logging in, just the username.  This would also be true on standard login boxes if you configured the security settings to default to your domainname.

Thanks tech. I've already tried the netbios name; it doesn't work. (plus the customer thinks this method is still too long) I've asked the designer about your second suggestion, he'll get back to me via e-mail shortly. there is a standard and windows logon feature in the web page, but standard doesn't work and windows requires the long name. I'm aware that these buttons are really just text fields going to god knows where (minus the guy who wrote the thing).

Still, is there something I can do to give an easier logon name without changing the domain, or using forms based authentication -until he can get that feature running?- if i could get a username@xxx.local logon alias going the pressure would be lowered substantialy until we can get this figured out. all i know is that for it to work though the real domain name would have to remain as the active username for the web page to authenticate with. No is still an acceptable solution to this question.
