try this.

suggest you can change maxpacketsize 1 force the computer use kerberos traffic over tcp instead of udp. this, follow these steps:    

  • start registry editor.
  • locate , click following registry subkey:
    <samp>hkey_local_machine\system\currentcontrolset\control\lsa\ kerberos\parameters</samp>
    note if the parameters key not exist, create now.
  • on the edit menu, point to new, , click dword value.
  • type maxpacketsize, , press enter.
  • double-click maxpacketsize, type 1 in the value data box, click select the decimal option, , click ok.
  • quit registry editor.
  • restart computer.

hi.

on server using regedit modified registry key (1) default value of (0)
   hkey_local_machine\system\currentcontrolset\control\lsa\kerberos\parameters
   entry: loglevel
   type: reg_dword
   default value: 0

kdc_err_s_principal_unknown 0x7 server not found in kerberos database

http://www.ietf.org/rfc/rfc4120.txt kerberos protocol registry entries , kdc configuration keys in windows server 2003

http://support.microsoft.com/kb/837361/en-us

in addition, whether account using third party programs when error occurs?
