I've found a work round for the moment. I am exporting the data on the Win2k box to the local Linux box via smbclient and then using rsync between the two Linux boxes. This doesn't freeze and runs nice and fast.

Instead of copying the data using smbclient, you could smbmount the win2k data and have the Linux box export it without copying. I have used this method to mirror gigabytes of data from an NT server to a Linux box over a 128k link without any problem.
