Network Access Denial after XP SP 2 applied.

[Guest]

When i apply the Win XP Service pack 2 computer refuses to give access to
other computers on my internal network. This computer is directly connected
to the internet and ICS is enabled on it so as to provide internet access to
the rest of the pc's on my internal network. It even denies to provide IP
address to client Pc's.

Service Pack 2 automatically turns on the Windows Firewall. You need to
configure the Firewall to allow lan traffic as Trusted.
