[Samba] Cannot mount Windows 7 share with CIFS Error 112 Host is down

[iancshay at comcast.net]

Hi. I just got a new Windows 7 Home Edition computer and am unable to mount its shares on my Linux system. 
I'm running Fedora 11, samba 3.4.7 
I have no trouble mounting shares from XP systems on the network using the mount command below. 
I can access the Windows 7 share with no problems using smbclient on Linux. 
The Windows 7 share is accessible from the XP systems. 
Here is the mount command: 

mount.cifs //pirin/c /mnt -o user=yanko,uid=500,gid=100,file_mode=0666,dir_mode=0777,noperm,iocharset=utf8,directio,ip=192.168.1.12 
Password: 
mount error(112): Host is down 
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) 

The dmesg log has: 

CIFS VFS: No response for cmd 114 mid 1 
CIFS VFS: cifs_mount failed w/return code = -112 

I have not found any errors logged in Windows 7 but perhaps I don't know where to look. 
I can access the Windows 7 share with no problems using smbclient on Linux. 
Any ideas will be very much appreciated. 
Thanks!
