Important
When you enable SecurID authentication on a computer running Microsoft Windows Server 2003, the Network Service account must have read/write access to the following registry key: HKLM\Software\SDTI\ACECLIENT.
Kerberos authentication depends upon User Datagram Protocol (UDP) packets, which are commonly fragmented. If your ISA Server computer or array is in a domain, and you enable the blocking of IP fragments, Kerberos authentication fails. For example, if the computer uses Kerberos for authentication during user logon, logon fails. In scenarios where Kerberos authentication is used, it is recommended that you do not enable the blocking of packets containing IP fragments.
