Files copying SLOW via 100bT server-to-server.

Hello. I am transferring files from an NT4 server, to a WindowsServer2003 server, both are on 100bT ethernet on the same subnet, but different NT domain. I am copying 5 gb of files in one drag-n-drop "copy" swoosh, via remote drive mapping.

It works fine, but it's SLOW - it's copying about 1mb per minute, that's it! If I OPEN a 1 mb file from the remote (mapped) server, it opens in a second, but the copying is MUCH slower.

Anyone know the reason for this? Can I do the copy any faster? Is it related to the cross-domain issue?  (I don't see how it could be.)

Thanks for any advice -

A similar problem was discussed earlier.
This was not his issue but check it first.
verify if your port speeds are set to auto that they are not flopping.  (do you have a managed switch?)

if you do not try forcing port speeds on the NIC and Switch to a value such as 100bt FD.
(if all hardware supports that)

first thing to verify is the port speeds. verify switch settings are 100 and everything. you would probably benefit from using xcopy in dos rather then windows copy. It works a little more efficient for transfers like this
