Remote Procedure Call (RPC) Locator

Name service provider that maintains a database with available RPC services on the server, where local RPC services can register themselves. A client can then contact the RPC locator on the server to locate and access the wanted RPC service.

This service is used by IIS to register what computers available for remote administration.

Note after installing WinXP SP2 one might get the following error:

Event ID: 1000
RPC locator has encountered a problem and needs to be closed.

Note in Windows Vista and later versions of Windows, this service does not provide any functionality and is present for application compatibility.

    I am running an RPC based server and RPC based client on different machine (both system having Windows-XP Professional with service pack 2). The problem I am facing is client is not communicating with RPC Server. I have seen that RPC Server exports its information to name servide database(i.e. to local RPC Locator) but still client is not able to find location information about server from Name service. Can you please let me know what configuration I have to make in both systems to make it work? Whether it has to do any thing with RPC Locator?
    Thanks in advance

    Don't have much experience with configuration of RPC communication for 3rd party products. I recommend that you find a developer forum or newsgroup where others are posting similar questions.

    I have found these articles that describes some of the changes made to RPC communication in XP SP2:

    RPC interfaces restriction in Windows XP SP2
    Changes to Functionality in Microsoft Windows XP Service Pack 2
    List of Remote Procedure Call (RPC) fixes in Windows XP Service Pack 2
