Sonicwall Network DHCP not working

Hello,

I have a Sonicwall 240 with a few unmanaged switches and a Linksys Access Point.  On Friday I noticed that no email was coming through and I couldn't connect to any of my RDP locally.  I checked my laptop and other PC's and noticed I wasn't getting an IP address or the system getting and unidentified network or internet access.  However, when I connect to the wireless network I'm able to get to the internet and of course still cant connect to Servers because its on the LAN.

What can I check for?  I'm able to logon to Router and DHCP is enabled.

Dumb question, but have you reset your SonicWALL?

Also, if you have an Active Directory domain on site, I would just use Windows DHCP server; it makes life so much easier.

^Reboot is probably a must.
What gives the WiFi devices their DHCP? Is it provided by the APs?
What IP address do the APs get?
What IP address do the WiFi clients get?
What IP address is the Sonicwall DHCP service on?

Every was fine with the Sonicwall, I replaced the switch and all devices started to get connection.  The Exchange server had problems with accessing the network.  After reviewing the event logs it all pointed to the DNS on the AD Server.  After we resolved that the services on the Exchange was able to start.
