DHCP Error

A system on our network is having major trouble keeping a DHCP IP Address.
The system is a laptop and has a bluetooth keyboard and mouse installed. We
were seeing this unit dropping it's DHCP IP Address about 4 times a day. We
replaced our 6 year old 24 port managed switch with a new switch. Two days
have gone by went an error and today she came up with a DHCP error. Below
are our log files from when McAfee paused to the notice that she has lost her
IP Address and picked up a default loopback address. When this happens the
system goes into "offline" mode and she does not notice it until she gets an
ODBC error in trying to access a SQL Server application.

Can someone please give me some ideas about what I need to do to fix this?!?

Thanks - NC Beach Bum

I would go to EventID.net and search all of these IDs. You might find
something, and you might not. At least there's a might!
