Losing IP in SP2

[Guest]

Hi

Ever since i installed service pack 2 for win xp pro. It keeps disconnecting
the lan connection. The connection loses a ip address and cant find one from
my dsl modem which is fine even the other computers on the network are fine.
Even when i use a manually assigned address it still loses it. The only thing
that i can do is restart and it works perfectly fine. The problem usually
occours when i leave something downloading or if im just not at the computer.

Can anyone help me at all ?
Thanks

There is something broken in netowrk connections in SP2.
I have similar problems. My XP SP2 PC cannot connect to
my router w/DHCP (it worked ok for a few days then just
stopped working), yet a laptop and other desktop connect
perfectly fine with the router via DHCP. It doesn't
matter if firewall is on or off. Even if I force an IP
setting, the PC does not talk to the network (pinging my
router is not recognized). I have the same problem with
SP2 PC finding an IP w/ a wireless bridge these are both
linksys products). I know it's not the PC LAN hardware,
because for some reason connecting my broadband modem
directly to the SP2 PC, it does connect (and find an IP
address via DHCP)...completely lost...?

Disable the Windows firewall if there is a third-party firewall running.
Then open the TCP/IP properties, Advanced, Options tab, TCP/IP
filtering, and Enable filtering, change settings to Permit all, apply,
then disable filtering, apply. See if this helps.

Another thing to try, reported to fix broken/spurious network
connections is to run the network wizard several times. Don't know why
this might work except that the networking/security/firewall not running
cleanly or not saving data to all registry keys.
