Dennis,

In large installations, I've always found it helpful when diagnosing LAN issues to isolate floors and departments first 
- using routers or with devices that can do transparent bridging.  That way, you can walk through each dept/floor 
testing for the issues, and hopefully find only one location its still affecting.

Its entirely likely that there's either a loop of some sort or a switch has gone off the deep end.  

If you'd like, let him know if he wants to drop me a mail, I can walk through details about the situation and hopefully 
help him narrow it down.

have a friend who has 21 floors of a building in DFW, multiple switches, etc and they started to have latency issues 
this weekend where half if not all packet are being dropped to folder shares, printers, etc. Suggestions on how they 
can troubleshoot that? call in a company to help identify it?
