oracle 8i and mts problem

Hello there, Oracle users!
I am new here, as new to the Oracle technology. We are developping a software which must be transaction compliant, and we're on microsoft platform, and thatswy we're using sql2000 and microsoft transaction server for our application server components.

But one of our clients wants to use oracle 8i db as the resource manager. We had to make the proper work mts with oracle. I've red all of the oracle documentation within this topic, and i successfully installed the Oracle Services for MTS on our development machine at the workplace.

(created the mts_proxy_info table, granted the specific roles to a specific db user, the specific privileges, and so on), and it is working nicely, the log says "accepting new enlistment requests", everything is wonderful.

But at the client, i repeated all of the steps (the only difference is, that they have the server on a HP-UX machine instead of winnt and i had not access to the oracle server, i just gived the sql script to the oracle dba guy there (maybe he missed something?)), and when i wanted to start the oracle services for MTS on the Application server, the log says this: "incorrect password, or username". I really don't undestand it, because i can connect through the OLEDB driver with the specified username, password and Service name. (in a datalink (udl), for example)

If anybody had an idea i would be very happy

thanks in advance,

daniel szabo

ps: the app server config is:
nt 4.0 server
sp 6
option pack 2
iis 4
mts 2
script host 5.5
