You will need to do troubleshooting at two levels here(Network and Datalink.
When these users loose connectivity, what is the furthest that they can
reach (traceroute out to the NET, see how far they got, from the
workstation). You can also do some datalink layer troubleshooting by having
a console logging one of the 5505's for example. This could be spanning
tree pruning. Has any new equipment been added, any new ports turned up in
the past 3 days ?
Can the users ping one another, can they ping the switch. Can you reach the
switch?
