I have one network with - / +50 computer.

Lan and last days, has Apparent fail. Don't make any change the network.

Apparent fail moments by the network, and does not understand why.

That is there any software can analyze the network failures.

Some troubleshooting I've done: Changed the switch for better (3com); Passed-the new cable to the router.

edit: Example: I'm doing ping to our internal server, "requests timed out" The share folder takes long to open file (due to network outages) We lost our connection to the internal webserver.

But only in a specific network part in the other half of all network works to 100%

Failed how? What are the symptoms? –  David Schwartz Nov 19 '12 at 15:31
    
I assume you're on a domain? Or work group? –  Dave Nov 19 '12 at 15:36

Okay, so when ping fails, is the cable lit up on both ends? Do you get a valid IP address assigned? Does your ARP table contain the correct hardware address of the machine you are trying to ping? You need to keep troubleshooting until you find the very first thing that doesn't work. –  David Schwartz Nov 19 '12 at 17:05

Wild shot sounds a bit like you have a dns lookup issue.. check your DNS forward and reverse lookups on you domain controller. You may have a device or two with the same or more than one IP address.
