Constant DHCPREQUEST

[Gary Stainburn]

Hi folks,

While looking at my network I've spotted that my laptop is constantly sending 
DHCPREQUEST.  Everything appears to be working fine, both on my laptop and 
elsewhere apart from this. One other client, a Win7 PC appears to have the 
same problem, but everything else on the network seems fine and refreshes 
only infrequently.

Any ideas?


/var/log/messages on my laptop:
