I have two Compaq Proliant 3000 with the standard 9 GB drives. One has Win2k the other has NT4. Both have most up to date SP and drivers for the entire system. When I back up or copy anything from an NT4 box to the 2k box it is slower then frozen pond water. This is the case when I try and move, copy, backup anything that would involve a file coming or going cross platforms. I need help, I can't be the only one with this problem.

Hi.

After you upgrade to sp1 for win2000,sp6a for nt,
latest rompaqs for compaq and your scsi controller, say what's up.

Mark.

Do you have any file compression? NT to 2000 is still new but I believe I have heard that it may be buggy.

Is the network connection set as autodetect for speed & duplex? I definitely recommend hardcoding it at full speed / half duplex for testing.

May be a security issue. For testing, create an account on both machines [or login to the domain as the same user] and see if the copy goes any faster. You may also want to make that user a local Admin on both systems. Try the copy again after this is setup and see if the copy goes any faster [I'm assuming copies to other systems are "faster" so I'm leaving the nic issues to the previous answers].

I have heard of a problem copying between the two when both source & destination are NTFS compressed directories and the NT machine is sp4 or below. If this doesn't apply please give more info on source & destination. NTFS, FAT, FAT32, cluster size. Also some more info on network connection. Protocol, media, speed, duplex, NICs, same or different subnet, HUB or Switch. Are both servers, w2kpro, NT wrkstn ? With more info someone will solve this for you.

I have seen timing conflicts with 100base-t adapters and hubs that resulted in transfer speeds equal to a 14.4k modem connection. Try dropping both machines to 10base-t and see if the speed dramaticly improves. If it does, try a differnt brand switch between these two devices. The timing conflict is usually between the adapter and hub.

You would think that the con artists that post "If you solve a question, you should close it" would be disqualified from recieving points. If anyone else feels these freeloaders should be disqualified please give techrepublic the feedback on this matter. They are stealing points from people who try to give valid answers.

Often name resolution problems between w2k & nt, try to update each machine's hosts files (winnt\system32\drivers\etc) by adding the other's ip address. Quite simple to do and very effective in most cases. (There's a explaination on what to do in the file's header)

Hope it helps
