Question

i am new to linux and samba server.

i try to setup samba server. my windows 7 and windows 10 can connect perfectly to samba server.

the problem is windows XP cannot connect nor browse the samba server, it said : "windows cannot find "\server". Check the spelling and try again....."

and this is my conf setting :

[global]
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
unix password sync = yes
winbind trusted domains only = yes
username map = /etc/samba/smbusers
os level = 20
client min protocol = NT1
encrypt passwords = yes
map to guest = bad user
workgroup = WORKGROUP
netbios name = server
security = user
panic action = /usr/share/samba/panic-action %d
guest ok = yes
lanman auth = yes
log file = /var/log/samba/log.%m
max log size = 1000
ntlm auth = yes
passwd program = /usr/bin/passwd %u
obey pam restrictions = yes
logging = file
winbind use default domain = yes
server string = 
usershare allow guests = yes
auto services = global
server role = standalone server
pam password change = yes

please help

Solution 1

You have 'client min protocol = NT1' set, there is another similar setting 'server min protocol' which from Samba 4.11.0 is set to SMBv2. Your XP is probably only using SMBv1, so it will not be able to see or connect to your Samba server.

So you have to edit the [global] section in the /etc/samba/smb.conf and add the server min protocol = NT1 option here. Then restart the Samba service.

Solution 2

With a old Windows XP and Samba 4.9.5 on a Debian 10

server max protocol = NT1

lanman auth = yes

ntlm auth = yes

There were changes because of WannaCry and windows being impacted by it... Was your XP patched for that (XP was EOL and thus patches weren't generally applied) and used an older SaMBa version than is used today. Is your XP using a modern vers= option? Your issue is likely with the XP machine and thus off-topic here.

thanks for the clue, i will try to search for the patch. is it KB4012598 patch if i am not wrong ?

Does this reference help in any way? wiki.ubuntu.com/MountWindowsSharesPermanently

@User24601 i will check that out, thanks will update if works

And just anecdotally, setting server min protocol to NT1 and restarting smbd and nmbd may not be enough. You may need to reboot the server to reinitalte the master browser process.

@Morbius1 i will try your suggestion, thanks for the clue

For the search engines . . . C:\>net view \\myserver resulted in "error 71": System error 71 has occurred. No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept. Adding server min protocol = NT1 as above fixed that. Thanks!

Adding server min protocol = NT1 was not enough in my case. I also needed to add lanman auth =yes and ntlm auth = yes as explained in this answer. And it was enough to just restart Samba... in my case using the command: systemctl restart samba Thank you.
