samba write issues with windows logon

I have done the samba share implementation using following steps:
http://www.cyberciti.biz/faq/unix-sa...hare-writable/

I can access the share from Windows on first day and did write and read.
But starting next day possible after rebooting the samba server which is running on RHEL6.5 write permision is denied ever since. It is pissing the shit out of me.
the writeable = yes flag is set and checked everything but still can not see what is wrong. the testparm return the samba status but it does not include the writeable flag (below). What could be the issue?

You have valid users as well as a guest ok directive. Do you want windowsapps to be a public share?

You also have to verify the /sdb1/window.apps directory permissions and selinux if active are set correctly.

i did chgrp and chown from root to samba_guest on the shared folder. so far so good. not sure if it is temp band-aid or will occur again will see.
