Copying from Win2K3 to Windows 2000 professional - VERY SLOW - FAILS

[ssm_dmc]

I have Win 2000 professional on one machine and recently installed W2K3 SP2 on another machine.

I was trying to copy few files/folders from W2K3 SP2 machine to a Win 2000 Professional machine.

The copying process was terribly slow. Didn't complete in 1 hr.

So I cancelled it.

A folder of same size could be copied from Win 2000 machine to W2K3 machine within few minutes.

I have W2K3 (NO SP2) on another machine. So I tested the file trasfer beween windows 2000 and the Win 2K3 machine.

Didn't faced any problem.

What's wrong with the SP2 OS?

Thanks

Could be the addition of SMB2, but it's hard to say. Would be interesting if you got a network trace and saw what protocol was being used to transfer the files, and if there were any window size issues or retransmit issues causing problems.

I found the problem. It was the wrong network driver. W2K3 installation by default installed that driver.

I updated with the lates available form the HP's website,and set duplex-spped to 100mb full. That fixed it.
