samba - May 2002 - annoying authentication failure problem: sambatest[hostname]

Hello,

I have a little problem which appeared when I installed first 2.2
generation sambaserver on linux and same effect when updated 2.0.3 to
2.2.2 on hp-ux.
The actual problem is that my security servers log (NT4 server) get's
failure message every time someone connects to samba share which is
quite log and it get's frustrating to search real information from logs
when this failure message fills log. Fortunately the service works fine
and this problem is transparent to a user but bothers administration...
If someone would have a tip to remove this feature it will be highly
appreciated.

about authentication settings

security=server
password server=[NT4 servername] which is also pdc

the error message from nt eventviewer security log:
