[framework] problems with scanner/smb/smb_login

[Nik]

Hello list!

I'm having some problems with auxiliary/scanner/smb/smb_login module.
It simply doesn't work for me and I cannot understand the reason.

In my environment attacker machine is BackTrack5, target - windows XP
sp2 eng. Password for Administrator account is 'network'.

msf  auxiliary(smb_login) > set rhosts 172.16.10.10
rhosts => 172.16.10.10
msf  auxiliary(smb_login) > set SMBPass network
SMBPass => network
msf  auxiliary(smb_login) > set SMBUser Administrator
SMBUser => Administrator
msf  auxiliary(smb_login) > run

[*] 172.16.10.10:445 SMB - Starting SMB login bruteforce
[*] 172.16.10.10 - GUEST LOGIN (Windows 5.1) Administrator :
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
msf  auxiliary(smb_login) >

Same thing happens when I'm using USERPASS_FILE with values:

Administrator network

There is no firewall between computers and network shares are
definitely opened on the target machine, as smbclient works like a
charm:

# smbclient -L \\\\172.16.10.10 -U'Administrator'
Enter Administrator's password:
