My setup:

Linux box = Slackware 12 - this is at 192.168.1.101

Windows box = Windows XP Pro - this is at 192.168.1.100

I have been able to connect to and mount the shares on the Windows box just fine, until I was VNCed into the Linux box from work, using the Linux box in KDE and tried to connect to the shares from within KDE.

Now I can't connect or even get a smbtree of my Windows XP box from my Linux command line. I can go from the Windows XP box to the Linux box, however. So it seems like the Samba server on the Linux box is fine, but the client is not.

Here's some of the info I have:

I tried smbclient -L 192.168.1.100

It responds with:

session setup failed: NT_STATUS_LOGON_FAILURE

My samba log file(/var/log/samba.192.168.1.100) says:

[2008/04/28 12:45:01, 0] smbd/negprot.c:reply_nt1(317)
reply_nt1: smb signing is incompatible with share level security !

Running smbtree, I get:

cli_rpc_pipe_open: cli_nt_create failed on pipe \srvsvc to machine WINXPBOX. Error was NT_STATUS_ACCESS_DENIED

I haven't found anything that has helped me so far with this. I'm just not sure why it all of the sudden stopped working. Any thoughts on this are appreciated.

Sometimes this error is symptomatic of the windows server having anonymous access disabled. Could that have changed? I would ask the windows admin.
