CAUSE:

Behavior of the Remote Procedure Call (RPC) protocol is changed after you apply Windows XP SP2 in the following ways:
• By default, the behavior of RPC clients in Windows XP and Windows XP SP2 is to request endpoints from the RPC Endpoint Mapper anonymously.
• By default, the behavior of the RPC protocol in Windows XP is to permit anonymous requests to the RPC Endpoint Mapper.
• After you install Windows XP SP2, the RPC protocol does not permit anonymous requests to the RPC Endpont Mapper but requires client requests to be authenticated.
• Because, by default, RPC client requests to the Endpoint Mapper are made anonymously, these client requests fail after you install Windows XP SP2.
The failure of anonymous RPC client requests to the RPC Endpoint Mapper creates an inability to use the RPC protocol. This inability prevents the ENTSSO service and the BizTalk Application Service from starting. This behavior occurs because the ENTSSO service depends on the RPC protocol and the BizTalk Application Service depends on the ENTSSO service.
RESOLUTION:
If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To allow client requests to the RPC Endpoint Mapper to succeed, you must require client calls to the RPC Endpoint Mapper to be authenticated. You can enforce authenticated client calls to the RPC Endpoint Mapper by running the Group Policy Object Editor or by creating a registry entry. Use one of the following methods to require client calls to the RPC Endpoint Mapper to be authenticated.
Use the Group Policy Object Editor to enforce the use of authenticated client calls to the RPC Endpoint Mapper:-
1. Click Start, click Run, type gpedit.msc, and then click OK.
