I have linux centos m/c on which I am running squid and sabma. I my /var/log/message file following error is coming. I am not able to find why it is coming the below message is coming in my m/c with an ip 191.254.178.76.
There is another linux centos m/c on the same network with an ip address as given in the message.log file i.e. 191.254.178.14 and on that m/c also samba is running. Is my m/c samba services conflicting with the other m/c. How can i rectify this problem. As i am new to the linux os a step by step help will be much appreciated.

thanks

Following are the lines which are coming in the message.log file

"Jul 25 15:54:45 localhost nmbd[2852]: [2012/07/25 15:54:45, 0] nmbd/nmbd_packets.crocess_browse_packet(1067)

It seems no one has a solution to my problem. There were more than 100 views.

Can you show the status of service smb status & service nmb status of your m/c where your are receiving the samba errors.

smbd and nmbd services are running
when i give the command "service smb status" it gives me the following output
smbd (pid 2849) is running...
nmbd (pid 2852) is running...

Can you show the uotput of grep -i 'security' /etc/samba/smb.conf as if your security is set to domain then you will receive the messages which m/c are in the domain.

The following message is being displayed when i give the command grep -i 'security' /etc/samba/smb.conf

# Security can be set to user, share(deprecated) or server(deprecated)
security = user
# Security must be set to domain or ads
# Use the realm option only with security = ads
# Use password server option only with security = server or if you can't
# Security must be set to user for domain controllers
