During installation I updated my workgroup to "Workgroup" , after installation I changed it to ubuntu as I was unable to access computers in network . What changes do I need to make in samba configuration ?

I don't know if this is related , shared@shared:~$ testparm Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Loaded services file OK.
