Strange Nagios Problem montoring Windows 2012 R2 SMB shares.

[robk]

I have one server that refuses to respond to nagios... The remaining 4 work as expected.

 

With a working server I get

 

root@nagios-1:/etc# smbclient -U guest -N -L qegs-sage
Anonymous login successful
Domain=[QEGS] OS=[Windows Server 2012 R2 Standard 9600] Server=[Windows Server012 R2 Standard 6.3]

None working Server

 

root@nagios-1:/etc# smbclient -U guest -N -L qegs-facility
session setup failed: NT_STATUS_ACCESS_DENIED
root@nagios-1:/etc#

 

Both servers appear to have the same firewall settings etc.

 

Of course the one that doesnt respond correctly sometimes hangs so I could really do with the monitoring working.

 

Does this ring bells with anyone?

Sling a "-d3" (debug level 3) into the command:

smbclient -d3 -U guest -L qegs-facility

 

to get more info about what's happening.

With the debug info I get.

 

Working server.

The none working server. It seems to be the session setup failed stage that is the problem, but not sure what I need to change to enable it.
