mit kerberos error 147

[Wilfrid]

Hello,

I am brand new in the kerberos world.
I test my kerberos connection with the mit package. Using the leash 
application allow me to test my ini file.
On one desktop (XP sp2) leash connects to the kerberos server without 
problem. On several other machines it does not and returns:

Ticket initialization failed, Kerberos 5:KDC reply did not match
expectations (error 147).



I understand this is a desktop config problem but I have no idea where to 
look. Can anyone help me?
thanks
Wilfrid
