[Samba] Can't become connected user!

[Oleg Ruso]

Hi list!
I`m using FreeBSD 9.2 system and Samba version 3.6.22.
Everything working good, all windows clients (XP 64) have a connection to common resource. But i receiving lot of alerts in the message logs
-----------------------
smbd[10892]: [2014/01/31 15:30:55.159674,  0] smbd/service.c:995(make_connection_snum)
smbd[10892]:   Can't become connected user!
----------------------
All my actions ware useless......

-------------------------------------------------------------------------------------------------
[global]
        workgroup = smbdomain
        netbios name = router
        security = user
        valid users = User1, User2 ......
        invalid users = root
        allow trusted domains = yes
        oplocks = yes
        read raw = yes
        min receivefile size = 16384
        use sendfile = true
        bind interfaces only = yes
        interfaces = 192.168.0.8/28
        smb ports = 445 139
        wins support = no
        socket address = 192.168.0.8
        lm announce = no
        encrypt passwords = Yes
        passwd program = /usr/bin/passwd %u
        hosts allow = 192.168.0. 127.
        hosts deny = ALL
        guest ok=no
        log file = /var/log/samba/log.%m
        max log size = 50
        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
        getwd cache = yes
        wide links = no
        write cache size = 0
        aio read size = 16384
        aio write size = 16384
        aio write behind = true
        dns proxy = no
         local master = no
        username map = /usr/local/etc/samba/users

[public]
   comment = Public
   path = /smb/share
   read only = no
   browseable = yes
---------------------------------------------------------------------------------------------------------

But this comand performs without some alerts:

smbclient //host/public  -UUser1%U************
Domain=[DOMAIN] OS=[Unix] Server=[Samba 3.6.22]
smb: \>

I think, that`s a Windows trouble. But how to solve the problem? ...... just to switch off logging to messages? 

The recipe with a Windows regedit was testing..... is fruitless

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters
DNSNameResolutionRequired=0
DomainCompatibilityMode=1

Somebody knows something about? Thanks to all!!!!
