NT Domain Integration

[Woldstad, Jacob A MVP]

This is probably a frequent problem, but I haven't been able to find an
answer.

I recently installed samba 2.0.5a on Sun Solaris 2.6 server.  There is only
one share on the server that I want to be accessible.   I have set up the
share using the following smb.conf file: (obviously, the specific info has
been changed).

[global]
	netbios name = XXX
#Server has different name
	guest account = guest
	browseable = yes
	announce as = NT
	workgroup = XXX
	security = domain
	encrypt passwords = yes
	password server = PDC BDC1 BDC2				#not actual
machine names
	hosts allow = localhost, XXX.XXX.XXX.0/255.255.252.0,
XXX.XXX.XXX.0/255.255.252.0	#network segments that attach to this server
	wins server = XXX.XXX.XXX.XXX
	browse list = yes
	deadtime = 15
	domain master = no
	local master = no
	preferred master = no
	os level = 0
	domain logons = no
	follow symlinks = yes
	log file = /usr/local/samba/var/smblog
	server string = Server Description
	socket options = TCP_NODELAY
	log level = 2

[sharename]
	guest ok = yes
	guest only = yes
	path = /path/to/data
	writeable = no
	browseable = yes

This setup works fine for what we need, which is read-only access to the
share "sharename".  However, over the weekend, the machine samba is
installed on made a total of four identical errors on each of the following
machines: PDC, BDC1 and BDC2.  The error message, as taken from Windows NT
Event Viewer:

Event ID: 2006
Source: Srv
Type: Error
Category: None
Description: The server received an incorrectly formatted request from
\\Samba_Server.

Any help or direction would be much appreciated.

Thank you,
