Slow Network Logons

This is a flat network.No Vlans configured any of the switches as shown in the network diagram.when the users logon into the networkin any of the segment, it is very slow.It takes almost 15 to 20 minites to log into the network.This slow logon problems occurs only some days in a week. I cant predict as when these slow logon are going to occur. All of sudden this problem occurs.I think there is some broad cast strom happening in the network during these times.Please help me as how to troubleshoot and rectify as where the problems arising from.I consoled to switch S9 and said sh run ,The Hyperterminal result shows there is some problem happening in the network.pls see the attached file

Re: Slow Network Logons

Broadcast storm? Do your users have laptops, and thus would be modifying the network cables (plugging in, for example)?

If so, you may think about implementing Spanning tree of some kind. Our environment requires RSTP (or the Novell Client will cease to detect a tree) - but once we did that the laptop induced network loops stopped the user-created broadcast storms :)

You could try running a network sniffer when its slow. It may show you whats going on.
