Some devices are not getting connected to my LAN
Some devices are getting the APIPA addresses, when they connect. They can't get on the network. Our Sonicwall NSA2400 is the DHCP server. Even when I provide a static IP address, the ailing device would still not connect to the LAN. My laptop was connected to the LAN, hardwired, this morning. Now however, it's not connecting. My wireless is connecting though. I've seen this LAN disconnection, from 2 other devices today. Restarted my domain controller and an additional DNS server. A third DNS server cannot be restarted right now, because it is a file server that is used a lot, during work hours.

Switch failure or bad port on the Sonicwall. But I'd place my money on a bad switch, especially if it's a Netgear. You should be up and running in no time after you replace the switch.
I bet on switch bad ports too.
Try connecting a new switch and check if connectivity is restored
An other way to confirm that ports are bad is to connect a working laptop to a "bad" port

Replaced switch. Thanks for all comments.
Was this ever working properly before? If so, what's changed (hardware, configs, etc.)?
Check for another active DHCP Server on the LAN.
Let me know how it goes.
