DHCP disables itself automatically

Hi there,

The DCHP setting on my laptop continually disables itself. When I start my computer and activate the WiFi feature, I ususally have to goto Services and manually start the DCHP service.

I'm not sure if this has anything to do with it but the Event Viewer logged the following:

TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

And Also,

Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 000E35D43B7A.  The following error occurred:
The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Any help would be great!

Thanks,

DAN
