My machine will get an IP address from both my work network and DSL but after
about five minutes it will drop it and give me a 169 loop address. Even when
I get a regular IP address I still can't connect to the internet. It is
recieving ar requests but for some reason it will not talk back any ideas?
 
The 169 address may be the APIPA ( Automatic Private IP Address ) assigned.
How long are your DHCP leases set for? Normally an APIPA address is
obtained only if there is no DHCP Offer / ACK from the DHCP Server.

Normal ways that an IP Address change is triggered:
1) A DHCP lease if obtained has a lease lifetime. once this lifetime is
80% to being reached, the machine will try to release the address. It tries
this several times until the lease expires.
2) A user triggers an IPConfig /renew or IPConfig /release & IPConfig
/renew command
3) The interface drops into a down state ( disabled, connection unplugged
etc )
4) A user manually changes the IP Address ( may also occur using a script
etc. )

Can you use a network sniffer to see the DHCP traffic? Anything in the
EventLogs when this occurs?
