I have a question about APIPA and DHCP. Last year, when we lost our T1 to one of our remote sites the workstations kept their Dynamic IP address for the length of 7 days, based on the DHCP configuration, and then would begin to loss their lease.
This did make sense because if a DHCP server fails and the workstation is able to find its Gateway, the workstation will retain its Dynamic IP address.
However, last week I lost another T1 and I had to send my techs out to place static IP address on workstation so the users can do internal work. What changed? I have the same workstations; no changes have been made to DHCP server; and all of our workstations are 2000 or XP.
I have read info about 2000 machines and the APIPA being automatic if DHCP Server was not available the workstation would revert to a 169.254.0.0/16.
My questions is “What changed, was there an update from Microsoft in the last year that forces all machines 2000 or XP to not hold its leased IP address?”
Very curious about what changed. I know I can have my techs change the REG to prevent APIPA, but that is a long drawn out process.
