Cannot connect to DNS server over NBSS socket for port 139

[VKALVEMULA]

hi All,

i see the below error message on the filer.

[NAS02:nbt.nbss.socketError:error]: NBT: Cannot connect to server 192.23.47.238 over NBSS socket for port 139. Error 0x41: No route to host.

i see the filer can ping both the DNS servers.

did any one had same type of issue wrt DNS server connection ?

thanks in advance

Any followup to this?

139 is a CIFS port, DNS operates off TCP/UDP 53. Is 192.23.47.238 a windows server?

That error indicates a NetBIOS over TCP/IP connection problem. The filer is trying to connect via CIFS so the 192.23.47.238 address should be running Windows/Samba or something similar.

Can you ping from the filer's console to 192.23.47.238? Is it running Windows file sharing? Is there a firewall blocking ports 135-139 or 445 (all used for Windows file sharing in various ways)?

This error has nothing to do with DNS.
