Take the tour ×  I've setup Kerberos in my farm and things seem
to be running right, i'm coming across articles that talk about
registering the NetBIOS names of my webapps however and i'm
curious as to why i would need to do that when I have already
done it with the FQDN and things are working ok from what i can
tell.  Can anyone shed any light as to why the NetBIOS SPNs
would need to be created in my KDC?  share|improve this question

probably better served by ServerFault.  You need an SPN for each
type of connection that may be made. Because your configuration
uses FQDN's you are not having issues connecting via SPN
listening for that FQDN. if you tried to pass a kerberos token
via the NetBIOS designation you would fail and receive an error
stating the specified SPN could not be found.  For SharePoint
deployments it is common to use a NetBios name for internal
URL's and thus the recommendations to configure a SPN with
NetBIOS.  share|improve thi
