Hi all,



Now days iam stuck with a strange error from windows 7 clients .Not able to access smb shares from windows 7.Samba service is configured in RHEL 4 os.The same share can be accessible using netbios name from xp os.using name and ip address pinging is happening from both sides.


From windows 7 clients if i do \\<Smb server name> iam getting an error report which i attached with this.


from server i cheked the log file and i got some information wich iam pasting here:-



[2011/11/09 15:58:43, 1] libsmb/ntlmssp.c:ntlmssp_update(245)

Any one faced this problem ? Any valid responce will be appriciated.

before going any further ahead I would like to know

Have you tried accessing the samba share with IP instead of hostname from win 7?
have you made an entry of this hostname in the hosts file of windows 7?
and I am sure win 7 is in network with linux?

Have you tried accessing the samba share with IP instead of hostname from win 7?

Yes i have tried by ip address and iam able to access the samba share.

have you made an entry of this hostname in the hosts file of windows 7?


No i didn't added any entry in host file because all windows pc's pc's are member of a DC also linux server information is there in DC.FQDN and netbios name communication is happening from both server and client side.
Only the problem is share is not accessible using name.Do you want me to edit host file ? is it require ?



I am sure win 7 is in network with linux?

both server and clients are in same network.

If it is working with IP then I think you should give a try
make an entry of IP and hostname at the bottom of the hosts file

Hi,

No luck.

We are using rhel 4 version and we dont have subscription.Will updation be the problem?
If i reconfigure samba will it work?

Few things you need to check
and kindly use code to show the outputs as it makes easier to study everything.

There is no iptable configured in the server.The following are the things which you asked.

# Any line which starts with a ; (semi-colon) or a # (hash)

one more thing these window's PC's are member of a domain called ITTIAM.COM. if i logged in to local computer(this computer) iam able to browse using name.but if i logged in to domain iam unable to browse using name.


Iam suspecting like this is related to some domain related issue.Now my linux server working as a stand-alone server.Do i need to change this role?

In your hosts file
why have you commented all the hostname?
I guess you should remove those comments so that your machine can help you with name to IP resolution

it should be something like this
on windows

there is no luck.
