slow file copy from server to clients

I saw a strange behavior at a company which has an sbs 2003 server installed.
A file copy from the server to a client(s) goes very slow, but when I copy the file from the client to the server it goes very fast.
I didn't install this server, but I just noticed this strange behavior.
The sbs server isn't acting as dhcp server, and the clients have a static ip, so that part is already wrong, but I was wondering if that has smth to do with the slow file copy from the server to the clients.... .
I also noticed that, when I browse the clients(C$), the listing of the c-drive is also very slow.
 
server ip config:
   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : HP NC7761 Gigabit Server Adapter
   Physical Address. . . . . . . . . : 00-13-21-1C-6C-98
   DHCP Enabled. . . . . . . . . . . : No
   IP Address. . . . . . . . . . . . : 10.0.0.2

Client Ip config:

   DHCP Enabled. . . . . . . . . . . : No
   IP Address. . . . . . . . . . . . : 10.0.0.200
   Subnet Mask . . . . . . . . . . . : 255.255.255.0

   DNS Servers . . . . . . . . . . . : 10.0.0.2
   Primary WINS Server . . . . . . . : 10.0.0.2
 
Any idea what could be the problem?

Interesting that the slowness is Client ----------> Server because the other way around would most likely be an SMB signing issue that is documented here: (http://support.microsoft.com/kb/321169 -- applies to SBS2003 as well).  

However, the way it's happening for you, I'd suspect that it's the HP Gigabit Adapter which is known to have some issues now and again.  First thing you should do is to update the firmware and drivers for it:

If that doesn't resolve the issue, then I'd replace it. even if only temporarily to troubleshoot.
