Error -2147024891

Hello people.

I have this problem, error -2147024891, when I try to connect to licenses server

My scenario is:

My B1 is in Windows 2003 Server and the client is in Windows XP and ther isn't a domain. All computers are in a work group

I readed the article which talk about DCOMCNFG and I had all the steps in server and client.

Any idea?

Thanks in advance

PD: Sorry for my english
