We had a partial DHCP outage this morning because the failover system between our two DHCP servers malfunctioned. The problem is currently solved only preliminarily by disabling the failover system and one of the two servers. To get both DHCP servers working again, we scheduled a DHCP server maintenance for today, Friday, 30th of January 2009, starting at 5pm. There may be short DHCP service outages during the maintenance. This means that initially connecting to the network as well as renewing the DHCP lease of your computer may fail for a few minutes. Update 21:45: The DHCP service is working again including the failover system.

Detailed technical informations about the two issues caused these DHCP problems can be found in our wiki in the following two articles:

• Fixing dhcpd.conf for upgrade from ISC DHCP 3.0 to 3.1
• What to do if Windows Vista gets the wrong DNS servers via DHCPINFORM answers
