Oracle DB service - wrong credencials

Question

Hi, all.
We've got a problem with communicating between web server (Win 2003, IIS 6) named WEB and DB server (Win 2003 Itanium, Oracle 10g 10.2) named ORACLE.
DB service has to read the file from special folder at web server into BLOB using special dll function. A share is created for that folder with full access permissions to ORACLE$ account, meaning computer account of DB server.
This scheme works on about 10 our servers all around the country, but not on these 2 servers.
It works for two times (2 files are loaded) but when any user tries to load the third one (no matter, which user, which file) we get "Access denied" error while DB tries to read the file.
Windows Security logs show us, that for first two files Oracle server uses ORACLE$ account mentioned above, but then it starts using NT AUTHORITY\ANONYMOUS LOGON account.
We tried to restart servers, listener, DB service, but it never helps. After a while everything becomes OK again - again for two files - and then the same shit happens.
Any ideas?

"I've built a car to carry some people using special alloys, but it doesn't work"
Have you actually written some code? If so is it in one of Oracle's recognised languages - PL/SQL,SQL,Java - and could you share the code that is failing.
