Office WiFi / Internet Goes Down with Laptop Connection

My office WiFi network suddently has internet connectivity issues every time a specific user (with his personal laptop) connects to the network. I have verified he does not have a static IP. What else can I look for to stop this issue? We have a Windows Small Business Server that provides DHCP and DNS services to the local network.

Thanks

The fact that this is his personal laptop and it affects the company wifi would trigger a need to do some security/anti-virus scans on the laptop. The user may have an infected machine that is causing havoc on the network when its connected.

Is the outage restricted to his laptop or does it bring the whole network internet access down?

The entire network begins to have internet connectivity issues. Strangely, we can access local resources such as the shared drives and exchange server, but cannot browse the web or have intermittent issues browsing.

Interesting problem.

Is your router providing the wireless or do you have a separate wireless access point?

Do you have any issues if the user connects his laptop to the network via a cable?

I object to the reason for the question closure. You can't expect to get 'good answers' if you're not prepared to present further information when asked.

I think these two should be divided the points.

I think that some credit should be issued, while the question may not have been answered completely, to say "no good answers" is a bit harsh. There was participation on the question by more than one expert offering advice and asking for more information. The advice given was definetly good advice as well as valid.
