Samba under Fedora

[Mark A. Hoover]

I was wondering is anybody else here has had trouble mounting remote 
share points when using the Samba client that comes with Fedora.
 

I took a box with Fedora on it fully up2date'd and attempted to mount a
Windows 2000 server in a domain setup from my linux box.  The mount 
worked great, but it took almost 2 hours to copy 175 MB from an 
otherwise idle server.  When doing the same copy from a WinXP laptop, it 
took about 20 seconds.
 

Any thoughts?  Something I should be tweaking?
 

I've used the Samba server from Windows many times with great performance.
