Cannot connect to linux smb share from Windows 7 - error 64 the specified network name is no longer available

Hello,

I cannot connect to linux smb share from Windows 7 - error 64 the specified network name is no longer available is the error I get, but also network path not found error 53, and the specified server cannot perform the requested information

I have tried using the netbios name, the fqdn and ip address of the smb server.

Any ideas?

Thanks!

Are yoiu able to ping the IP address? Is this a new Samba share and have you allowed access through IPTables? Allowed access on the side of the windows client?

Please test telnet to the ports listed below.

netbios-ns 137/udp # NetBIOS Name Service
netbios-dgm 138/udp # NetBIOS Datagram Service
netbios-ssn 139/tcp # NetBIOS Session Service
microsoft-ds 445/tcp # Microsoft Directory Service

Hi,


Thanks for the quick response!

I am able to ping the ip, as well as the fqdn
it is not a new share, I am able to browse the share from a server 2208r2 and server2012 on the same domain as the windows 7 machines
I have disable firewall on the client
I can telnet into the tcp ports 139 and 445

OK, can you restart the workstation service on your PC and try the UNC path again?

I would use Wireshark at this point and filter for the specific traffic to see whats happening.

I tried that, and it seems that the connection is being re-set immediately. It happens when I try to connect to any unix based smb share, not just that particular one.

Are you able to filter for the traffic to the SMB server on your capture and post here if unsure.

I managed to narrow it down to one local  security policy setting:

"Microsoft network client: Digitally sign communications (always) - enabled"

The default appears  to be disabled, at least on all other machines I checked - enabling it causes the problem. I would very much like to know what caused this setting to become enabled. I don't think it is a GPO, as it keeps it  after moving the machine to a different OU (containing machines that work fine and don't have the setting enabled), or even after removing the PC from the domain altogether.

 It is a pretty standard image - Windows 7 Enterprise + updates, + management framework 3, + dependencies (.net 4.5, ms visual c++ redist, flash, java)+ U-EV client, Application Jukebox client. We have recently implemented PKI, if that may have something to do with it,  but as i said it seems to be a local policy, not a group one.


Any ideas on what might be the reason the setting became enabled?

Thanks!
