Win2000 Srvr SCSI vs. IDE issues??

Hi all,

I need an advice.

I am running Win2000 server on my cable line at home. I recently removed my SCSI drives (old 40MB/s kind) because the controller or one of the drives seemed to be acting up - the hard drives were hanging the system during file transfers - error messages that the system can't read form the drive. Now I run a 7200rpm 2MB Quantum ATA66 drive on the BXMaster ATA66 controller. The system doesn't lock up any more. The trouble is now that whenever someone logs in via ftp or I start copying files over the network the machine becomes unresponsive. I mean the client file transfers are not affected, but the computer itself hardly responds to mouseclicks and everything takes forever. I've never seen this happen with the SCSI drives before. This bothers me because I also use this machine to run AIM, Outlook and browse the web. The task manager shows that WINLOGON.EXE eats up 80-96% of CPU speed. But the RAM use is around 100MB, still within 128MB physical RAM. Once users log off the situation comes back to normal.

Before, I've had this ATA drive as a system disk, and SCSI drives as server drives and, like I said, I've never seen anything like that. Now one drive does it all.

Is it a problem in Win2000? I reinstalled after replacing the drives.

Is it because I have one drive for system and server use?

Is it CPU usage issue with ATA drives?

Is it RAM issue? I'm getting 256MB for this machine.

The machine is based on BXMaster mobo, 600MHz PIIIE, 128MB CAS2 Mushkin PC100 RAM, D-Link and Linksys NICs.

I consider the following:

1. Get another ATA66 drive and run separate drives for system and server files.

2. Get another SCSI controller. I am not sure though whether my original problem was caused by faulty controller or one of the three SCSI drives. I can't really aford a new controller AND new SCSI drive at this time.

3. In either case format and reinstall.

I'll appreciate any insights.

OK, it's not ATA drive issue: if I duplicate a large file, like 650MB disk image, the machine doesn't slow down despite of heavy disk usage - CPU usage goes up to 8-10% only. It only slows down if someone is connected either via ftp, Windows file sharing or AppleTalk and copies files :( I'm puzzled.
