[SOLVED] Unable to connect to SMB share from Win 10 Workstation

gtribe · 01-06-2020, 11:55 AM

First time installing and setting up samba on a CentOS 7 server. I can connect to the share from a Mac OS computer but can not connect to the share from a Windows 10 workstation on our university domain.

When I try to connect I get the message “The specified network password is not correct”. I’m using the IP to try and connect so the server address is \\ip-address\share and the username is clustershare02\username where clustershare02 is the hostname of the CentOS server. I can ping the server from Windows 10.

Here is my smb.conf file

Code:

[global]
	workgroup = WORKGROUP
	security = user

	passdb backend = tdbsam

	printing = cups
	printcap name = cups
	load printers = yes
	cups options = raw

; [homes]
;	comment = Home Directories
;	valid users = %S, %D%w%S
;	browseable = No
;	read only = No
;	inherit acls = Yes

;[printers]
;	comment = All Printers
;	path = /var/tmp
;	printable = Yes
;	create mask = 0600
;	browseable = No

;[print$]
;	comment = Printer Drivers
;	path = /var/lib/samba/drivers
;	write list = @printadmin root
;	force group = @printadmin
;	create mask = 0664
;	directory mask = 0775

[share]
	path = /media/raid02/samba/share
	writable = yes
	browsable = yes
	guest ok = no
	valid users = @smbgroup

Not sure if this is related but when I check the nmb.service I get this message.

Code:

When entering the username try just entering the username and not hostname\username.

I believe due to SMB version 1 support being removed there is no automatic lookup between IP addresses and netbios names between linux and Windows. It works between the CentOS and Mac computers because they are both running compatible network discovery services that replaces netbios i.e bonjour on the Mac and avahi on CentOS.

Although not the same thing you can also use filezilla or WinSCP to connect to your CentOS box which uses sftp to transfer files between computers.

I added ntlm auth = yes in the global section and after I was able to connect to the share from the Win 10 computer.

Good. I didn't have to on my CentOS 7 system so configuration could be different.

Thanks for the reply michaelk, hopefully this helps someone else.

Just for a frame of reference ntlm auth = yes allows ntlm version 1 clients and above to connect but by default Windows Vista and above should be using ntlm version 2 which is also the samba default. It should not be necessary to use ntlm auth = yes but it depends on how your Windows 10 security options are configured.
