All file copying from other machines to both drives on one 'puter 
suddenly got ten times slower.

No.

No, good idea thx.

I'm testing file copy. The 'puter is a media server.

Using the latest.

Focussing on file copy. Haven't fooled with internet speed tests on this 
box.

Replaced the cable to the problem box, no effect.

64 bit.

Heh it's a M$oft network, they always appear with lan access eg "The 
device name is in use, connection could not be restored" ... click on 
the factitious error msg, it goes away and the connection restores. Been 
going on for years. Delete and recreate the connection and the msg goes 
away till a laptop lid is closed and reopened. M$oft nonsense.


> Is either computer slow booting?

No. Funny question, the laptop I used to access the slowed-down server 
has had an SSD for 18 months, boot is insanely fast.

Servers have spinners. HD diagnostics report they're fine.

Ordered an Intel NIC, we'll see.

If it's not the NIC, I'll be back with more questions :-)
