SYMPTOMS
Programs that rely on the UuidCreateSequential Remote Procedure Call (RPC) function may not work, and you may receive an error message that is similar to:

- Entry Point Not Found

The procedure entry point UuidCreateSequential could not be located in the dynamic link library Rpct4.lib.



CAUSE
The Rpcrt4.dll (version 4.0.1381.7097) component that is included with Windows NT 4.0 Service Pack 6a (SP6a) contains modified UuidCreate functionality to match that of Microsoft Windows 2000, but does not export UuidCreateSequential.

The UuidCreate function was modified for security reasons so that it no longer uses the Media Access Control (MAC) address of the installed Ethernet adapter to generate Universally Unique Identifiers (UUIDs). UuidCreateSequential was introduced to allow the creation of UUIDs by using the MAC address of the installed Ethernet adapter.
