[Samba] smbclient works....mounting does not

[Dave Thomas]

Hi list,

I have a RH9 box at a clients site that needs to access a Win 2003 
server to retrieve files every morning. This has always worked well but 
our client decided to 'upgrade' the windows server they are using to 
2003 and I am having problems mounting the windows share to our RH 
system now. The thing that I cant figure out is why can I access the 
share and retrieve files using 'smbclient' but when I try to mount the 
same share I get the following error:

cli_negprot: SMB signing is mandatory and we have disabled it.
28694: protocol negotiation failed
SMB connection failed

This seems very odd to me that smbclient works just dandy but mounting 
is out of the question. Here is my global section from smb.conf...we are 
not sharing any directories from the Linux system. Oh...samba ver 
3.0.1-2 installed via samba-3.0.1-2_rh9.i386.rpm from the samba download 
site.

Thanks for any assistance on this.

Dave
