Samba: the account is not authorized to log in

Dear All,

I cannot connect from a Windows2000 virtual machine (VMware Server) to
a samba directory, as I get (in Windows2000) the following message:

"The account is not authorized to log in from this station". The
output of 'testparm' is below.

Any ideas?

Thanks in advance,

Paul
