Points to be considered
1. You can mount a particular shared folder and not the machine name or IP
For eg: You can mount //192.168.0.100/deepak but you cannot mount //192.168.0.100
2. You need to have login credential for the windows share access even if the share is accessible with full permission for everyone.
On Linux RHEL 5 or above
# mount -t cifs "//path_to_windows_share/Folder_name" -o username=deepak,password=my_password /mnt
On Linux RHEL 4 or below
# mount -t smbfs "//path_to_windows_share/Folder_name" -o username=deepak,password=my_password /mnt
Here /mnt is the local mount point on Linux. You can use any other mount point in your case.
Once the above command is executed make sure it ran without any error
# echo $?
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
//192.168.0.100/deepak on /mnt type cifs (rw)
Now you can use /mnt as any other linux directory.
# cd /mnt
Let me know your success and failures.
