Hello, Windows Server 2003 Service Pack 1 makes the significant change to
the Remote Procedure Call (RPC) service in Windows Server 2003 with the
addition of the RestrictRemoteClients registry key. This key enables users
to modify the behavior of all RPC interfaces on the system and can be used
to eliminate remote anonymous access to RPC interfaces on the system (with
some exceptions). Additional changes include the EnableAuthEpResolution
registry key and three new interface registration flags.
The changes to RPC in Windows Server 2003 Service Pack, has broken some
firewalls such Checkpoint, Microsoft ISA Server and so on. How ever hotfixes
have been released to address this issues.
