When mapping a drive from a Windows XP client to another Windows XP client
and both are members of the same domain and both are correctly registered in
DNS they use NTLM authentication instead of Kerberos. This is happening for
all XP to XP mappings in the domain. If any of these same XP clients map to
a Windows 2003 Server OS they use Kerberos. Is the Server service required
for cifs service principle name registration? Should XP to XP mappings be
using Kerberos? Thanks.
