smbclient to win2k3 share
 

when trying to use smbclient to connect to a share on my windows 2003 server box, it gives the following error:

tree connect failed: NT_STATUS_ACCESS_DENIED


to get around this, i browsed some newsgroups and found a post that said windows 2003 requires smb packets to be digitally signed. and that to connect to a share from smbclient you need to disable this requirement on the 2003 box by editing the registry:

Key: HKLM\SYSTEM\CCS\Service\lanmanserver\parameters\
Value: RequireSecuritySignature
Content: 0 to disable, 1 to enable

so i did this and now i can connect fine, but im kind of worried about opening my 2003 server up to attack. is there a way to tell smbclient to digitally sign smb packets? or maybe i need to find a different client?

thanks

Not an Expert...........
(User Login) is fairly secure for most needs which is what your likely using on the 2003 server for file shareing if your not using domain auth. I am not an expert, but I feel reasonable safe with that. yes it can be broken into but its not easy to do. it takes a bruteforce to do it usually and with decent logging you will notice that.

If your really concerned just do some google searches on 'smb security' to get started.
