Failure of Err.Raise statement in dll implemented in COM+

[AkshayB]

I have developed error handlling component which uses err.raise method to return error message back to the
user.

These component is placed in COM+ , and working fine
at server side, but on client machine its not working.
Client side I'm getting the error method xyz of object err_hndlr failed.

Client side tlb & vbr are registered using Clireg32.exe
utility

Is there any other way to notify message back to user from dll. Why err.raise not returning back to user.
