DHCP server not responding on 2008 sbs
Posted on 2011-10-24
Over the weekend I copied our 2008 sbs VM's VHD from one hyper-v server to another with more memory. Everything seemed to be working fine when I left on Saturday and most things are still working fine. However, any machines that were turned off over the weekend or that I hook up to the network today can't get an address assigned through DHCP.
I've confirmed that the service is running and if I assign the machine a static IP, it can ping and access the server normally.
I’ve restarted the service several times.
I've also used wire shark to confirm that the DHCP discover requests are being received from a machine with the correct hardware address.
I've also fired up the resource and performance monitor so I could see what the DHCP server is doing while a machine is requesting an address, it does not show any activity at all.
Nothing relevant is showing up in the event logs either.
