Look @ interface statistics (specifically errors) on the switch and
router. What are your switch and router make/model?

Subject: RE: Slow network - cause?
This site has 6 PCs, 7 VoIP phones, 4 network printers, 1 switch, 1
router. That's it.
No wireless.
They've never had a problem until yesterday. They tell me nothing has
changed.
Last night, all the computers were powered off (phones and printers were
still powered on) and it was still painfully slow and timing out when I
pinged the router.
Could be a device causing heavy traffic?
The T1 provider is now admitting that they see errors on the WAN
interface.
Hoping that this is problem with the T1 line...
Thx

Has this one site always been bad or is this a recent development? If
recent, what has changed? What's at the remote site? All workstations?
Or are there servers too? If there are servers, is local site traffic OK
but WAN traffic slow? Or is even intrasite traffic bad?
Any wireless out there? Any chance someone's fired up a WAP?
If it's a small site, like 10 devices or less, maybe have someone turn
off all the devices after hours and see what happens. If it's much
better, fire up the devices one at a time until you find a problem.
Could be a bad NIC on a PC.
But the best troubleshooting tool? Put wireshark on a local device out
there and start looking at the traffic.
