samba - Jul 2005 - INTERACTIVE logon works, NETWORK logon does not with Samba 3.0.14a

Greetings -

I have Fedora Core 2 Linux box with Samba 3.0.14a compiled 
and installed there.

Here's output of testparm:

<TESTPARM OUTPUT>
[root@cflinux ~/Downloads/samba-3.0.14a]# /usr/bin/testparm

[cf]

<TESTPARM OUTPUT>

Also here is my /etc/samba/smbusers

[root@cflinux /etc/samba]# cat smbusers
root = INTERMEDIA\backup
cf = INTERMEDIA\cf

In smbpasswd I have records for user "cf" and user "root".

I can connect from my Windows 2003 server to share "cf" as user
"INTERMEDIA\cf" when I logon to this Windows station with
"INTERACTIVE"
type of logon.

However, when I logon as the same user to the same Windows station with
"NETWORK" type of logon (e.g. to a telnet service), and then from that
Windows station, I cannot connect to the same Samba share on my Linux
box.
The error message I get is "Access Denied".

Further research in the logs shows that when I come to Linux box with
NETWORK logon, Linux box cannot determine that I am coming as
INTERMEDIA\cf user and attempts to connect me to that share as guest,
which is disallowed.
Eventually samba server sends NT_STATUS_ACCESS_DENIED message to the
Windows station. The appropriate log section follows:

When I connect with INTERACTIVE logon, the same log section looks 
like this:

Question:

How can I connect to Samba shares with NETWORK type of logon?

Thanks in advance.
