Hello, I was wondering we have a NT 4.0 domain which we cannot migrate to Windows 2003. Is there a way to have the NT 4.0 domain work with Kerberos so we can get single sign-on w/out the pain of upgrading to active directory? Thank you, Warren Coykendall P: 510-236-7730 x6652 www.palecek.com <http://www.palecek.com/>
