Linux Server/Win7 Client Samba Authentication Issue

I have a Linux server running RHEL 5.11 and Samba version 3.0.33-3.41.el5_11 for several years with no problems. With no apparent changes to the Linux server, client Windows 7 desktop or Windows domain controller, I can't authenticate my user name and password.


#======================= Global Settings ====


# ----------------------- Network Related Options -----------------
workgroup = huntergeo
server string = Samba Server Version %v

# ----------------------- Standalone Server Options ----------------
security = server
passdb backend = tdbsam

# --------------------------- Printing Options ---------------------
cups options = raw

# --------------------------- Filesystem Options -------------------
password server = tsunami
username map = /etc/samba/smbusers

#============================ Share Definitions ================

comment = Home Directories
browseable = no
writable = yes

comment = All Printers
path = /var/spool/samba
browseable = no
printable = yes

[lhotse a]
path = /data/lhotse/a
writeable = yes
guest ok = yes

The Windows Domain Controller has the following configured:
- LAN manager authentication level to "Send LM & NTLM - use NTLMv2 session security if negotiated"

When I attempt to map the network drive on my Win 7 client the login dialog box pops up as usual but it won't authenticate my user name/password. I get the following errors on the Linux server:

[2016/05/12 13:04:30, 1] libsmb/cliconnect.c:cli_session_setup(1028)
Server does not support EXTENDED_SECURITY but spnego is turned on
[2016/05/12 13:04:30, 1] auth/auth_server.c:check_smbserver_security(363)
password server TSUNAMI rejected the password: NT_STATUS_ACCESS_DENIED
[2016/05/12 13:04:45, 0] lib/util_sock.c:read_data(540)
read_data: read failure for 4 bytes to client Error = Connection reset by peer

May 12 13:36:15 lhotse smbd[20534]: [2016/05/12 13:36:15, 0] lib/util_sock.c:read_data(540)
May 12 13:36:15 lhotse smbd[20534]: read_data: read failure for 4 bytes to client Error = Connection reset by peer

Thank you for any help.
