Sudden slow in access

The automatic av scanning gets my vote. In any event, a remote process monitor might give you an idea. BTW, what server are you running?

Using the D-link 323 with 2 units of 1.5TB harddisks. It was working fine for 6 months, but suddenly it is slowing down alot while accessing files and working with it. This device is serving between 6 - 8 users at the same time. Hook up with a 24-ports 1GB switch and Cisco router.

There are 4 computers using 1GB network adaptors while the rest are using 100Mbps adaptors. It happens about a month ago when the files accessing is sluggish and slow. Nothing has been changed which is puzzling why this is happening.

Is there a way to monitor why the access using Excel is slow? Or software that can tell where is the bottleneck?

This is SOLVED.

Reason for slow access is due to the new 24-Ports 1 Gb Cisco Switch giving intermittent response. Change new Switch and everything is super fast again.
