Generating KRB5 keytab Ticket

[Talwar, Puneet (NIH/NIAID)]

HI,
 
I am having some issues creating krb5.keytab ticket on Windows 2000 server.
I have followed the direction on how to create krb5.keytab file from the
following URL below.
 
http://support.microsoft.com/default.aspx?scid=kb;en-us;324144
<http://support.microsoft.com/default.aspx?scid=kb;en-us;324144> 
 
 
Here is the command syntax I am using to create the keytab file and the
error messages that I am getting.
 
C:\>Ktpass -princ host/xxx.domain.gov at xxx.domain
<mailto:host/xxx.domain.gov at xxx.domain> .gov -mapuser macunis -pass password
-out macunis.keytab
Failed to set property "servicePrincipalName" to "host/xxxxdomain.gov" on Dn
"CN=Mac Unis,CN=Users,DC=xx,DC=xx,DC=gov".
WARNING: Unable to set SPN mapping data.
  If macunis already has an SPN mapping installed for  host/xxx.domain.gov,
this is no cause for concern.
Failed to retrieve user info for macunis.
Aborted.
 
If someone is help me out here as to why I am getting these error messages I
would appreciate it.
 
Thanks,
 
Puneet
