Using a UNC or Mapped drive to a network share to a server running SBS 2003 RC2 I experience SLOW file copies from the server to the client (get). Things go great in the other direction (push). I have several clients. This is the only one doing this. I can copy files from other clients to this pc no problem and I can copy files from external devices like flash drives to this pc. Only happens when I try to copy from the server. I have placed the pc in another location, replaced patch cables, hard coded the nics on server and client and even replaced the NIC to the client. All devices o the same subnet. All clients running XP Pro. There are no odd errors in event viewer. I set the LANMAN parameters to 0 on the server just to see if that would help. It did not.
