[jcifs] Re: JCIFS http filter problem with DC on Win 2003

One long shot theory:

When a client logs on, he is assigned a dynamically generated name.
Sometimes, the generated name can be resolved by the DC, other times the
generated name is not in the approved list. I'm completely lost here, is
this a valid theory?

The problem is, the only exception I get in the log is the "Access is
denied" for manual attempts. On transparent IE NTLM requests, I get nothing
in the log from NtlmHttpFilter. My log level is 4.

Thanks for any help!
