RPC Locator Issue

I have an XPe image on SP2 and FP-2007. I have an application that uses RPC
and is required for my task. As soon the application is initiated, RPC
Locator hits 98% CPU usage. After that even if I stop the application, the
RPC Locator keeps using 98% CPU usage. I have to stop and start RPC Locator
service to bring it back to normal.
We have been running this same application on desktops (literally 1000s of
them XP-SP2) has never experienced this. I am running the same application on
my desktop (again XP-SP2) right now with no issues.
Any help would be appriciated.

Kap,

I have no idea why RPC Locator service is so high CPU intensive on your system.
But I guess it may be related to some missing dependencies.

Have you tried testing your app in a full blown XPe image (like XPProEmulation from www.xpefiles.com)? (I have the XPProEmu image
running here and willing to test your app on that image if you wish to send me the binaries)

If the behavior is the same there (high CPU usage), I'd switch to Regmon (actually Process Monitor would suit better here) and try
to catch what's going on in the system when you launch your app.

Here is, just in case, the list of some RPC related components from the database:

(obviously, you already have the "RPC Named Service" which brings in the RPC Locator service)
