Slow file copies

[Tym Rehm]

I'm run Samba 2.07 on RH6.2. I have samba setup as a member server (I 
think) in an NT domain. When I'm copying files the samba machine to an NT 
machine in the domain it takes about 2-3 minutes for a 8MB file. If I copy 
the same file from one NT machine to another NT machine the copy takes 
seconds. I believe the security is set to server. Do I have something in 
the smb.conf wrong? Did I miss a step. Thanks in advance!
