Token validation is inconsistent

[Vishvesh888]

Hi,
I am having a very wiered problem. I am using kerberos validation.
Initially client sents the token to server and sever sends some reply token &
demands for next round of validation. And then finally server gives a token
that client has to use for further communication with server, handshake
complete.

This works fine for US AD server, but does not for UK AD server. I am using
Windows 2003 server.

Please help!

Thanks!
