b. Purge all Kerberos tickets by Kerbtray or Klist (Available at c:\windows\System32).

For example, a typical domain user has no special access or restrictions; token overhead is likely to be between 400 and 500 bytes. · Estimated value for ticket overhead can vary Step 3 - Negotiate Authentication: So now we negotiate the authentication protocol and the remote system responded; the response is the more important part of the packet. Create a new DWORD (32-bit) Value parameter with the name MaxTokenSize Specify the necessary value for the maximum buffer size (we have specified 48,000, since the size of user tokens do weblink Any other ideas?
