I am running windows 7, and have a win 2k3 DHCP server. I have multiple Dell swithces in my network. I have roughly 65 PCs, and for some strange reason, this morning, 5 PC's can't connect to my DHCP server. I can't ping the server, I can't browse to it. This happened 3 weeks ago and the only way I was able to resolve it is to replace the NIC with a new one.
When checking ipconfig, I have a good IP address, default gateway and the DHCP and DNS are both correct. I can ping any other server on my network.
So here's what I do to fix the problem temporarily, I note the IP address of the client, shut it down, delete the IP from the DHCP server, then boot up the client, do a ipconfig /release
and then a /renew and if that doesn't work, I have to do hte /release again, shutdown the client, and restart it, and then it gets a different IP, and it works for that day.
So this has happened to 5 PCs in 2 days. Not sure what is wrong with my DHCP server as I'm assuming that's where the problem lies?
