Bug in XP Professional perhaps? When I'm at home I use a
Linksys router to share my internet connection with my
laptop and home computer. My laptop is running XP
Professional. I receive my ip address and my ISP's DNS
suffix from the router via DHCP.

I noticed when I went to work that my network config was
not working. Even though I shutdown and powered off my
laptop, my DHCP provided IP address and DNS Suffix were
retained from home, so no wonder I could not connect to
anything at work. ipconfig /release and /renew gets me a
proper IP address for my office LAN, but the "DNS Suffix
for this connection" setting in TCP/IP Advanced / DNS tab
in my ethernet configuration still retains the old DNS
suffix. I have to manually delete that field. This
happens all the time, its not an intermittent problem.

1) Why doesn't a shutdown remove DHCP IP settings?
2) Why doesn't ipconfig /release remove the DNS Suffix
that was provided via DHCP in the first place?

Greg.
 
make sure Append these DNS suffixes is uncheck. to do this, go to the
properties of the connection>properties of tcp/ip>advanced>DNS.
