The network was fine yesterday and as far as I know nothing has been changed or added. This morning some computers are connected to our domain but most of them are reporting limited connectivity. On checking our DHCP server we are getting this message.
Cannot find the DHCP Server:
The DHCP server you specified cannot be located.
EVN: F13, dhclient-4.1.1-15.fc13.i686

My public interface (eth0) successfully gets a *real* public IP address from my ISP DHCP server; HOWEVER.....here's the issue:
- Valid public IP that the dhcp client gets from ISP is on 174.97.216.0
network.
I have a Huwawei modem and a TP Link access point, I did the setup everything works, the TP Link is using the DHCP of the modem.
Hey everybody. At my company I have encountered a strange dhcp server issue. Actually there are 2 issues. The first one is, in one of my ip pools I use deny unknown-clients statement, but if I create a host without ip address, only mac address specifid, the dhcp server thinks that the client is unknown. I have plenty of free leases.
We are experiencing an issue with users not being mapped to their corresponding network drives during the login. I verified that the logon script is correct and it work if I run it manually so I suspect there is some kind of network issue. When I run gupdate I get an error that states that Group Policy failed because of lack network connectivity to the domain controller.
Something weird happened today. We have a TP-LINK wifi router in our office distributing a pool of IPs 192.168.80-200.
I have a weird internal mic issue (It was working fine until the last kernel update) dmesg is reading the pci but when looking at the sounds setting it isn't showing.
I've recently installed Ubuntu 12.04 on a basic notebook with an i3 intel processor with 500 GB hard drive and 4 GB ram.
It seems like the installation went fine except for one weird issue. When I launch Firefox, it loads the Google start page (that's not the weird part.)
The odd thing is, it won't load any page other than the Google start page.
I took down my DHCP server to change some stuff, and after bringing it back up (down for 15 mins or so), I noticed that four other Ubuntu 12.04 servers set to use DHCP were unreachable. Running ifconfig on them returned just lo, so the eth0 and eth1 had been disabled.
I'm assuming the DHCP server missing caused them to shutdown the interface?
