I have found out that Kerberos Protocol Transition is available with
workstations: Vista onwards, Server: Windows Server 2003 onwards.
XP is just too old now.
(I know how it feels)

Protocol Transition is a feature of the server where the service resides
Client ---> Server1 > Server2
If Client ---> Server1 is NTLM (or Digest), then Server1 can do Protocol
Transition and get a Kerberos ticket for Server2 service, even if the original
protocol is not natively delegatable
