I have a XP laptop that is failing to accept inbound network requests through any Ethernet interface (wireless or direct). It appears that I have accidentally enabled firewall filtering; however, I have taken every action I know of to disable any protocol filtering. In the simplest situation, I am unable to ICMP-ping the IP address of the adapter from other computers on the LAN. Additionally, I am unable to accept inbound Netmeeting requests, remote desktop requests, etc.any inbound network requests on any tcp/ip port.
I would appreciate any advice on 1) hints on what I can do to diagnose the problem, or 2) if others have encountered a similar issue and can recommend a corrective action. I believe I have covered all of the basics to identify the problem (outlined below).
Thank you for any assistance.

a.. Internet Connection Firewall is not checked. Internet Connection Sharing is not checked.
b.. Advanced TCP/IP Settings, TCP/IP filtering, properties; Enable box is not checked, Permit All is checked for radio buttons for tcp/udp/ip protocols.
c.. Norton firewall was installed, now it is uninstalled. Norton Anti-virus is installed.
d.. ICF has been enabled, but it is now disabled.
e.. the IPSEC Service is stopped and no policies are assigned. At one time I was using IPSec to perform protocol filtering; however, all IPSec services on this machine are stopped currently.
f.. The Cisco VPN service is stopped, and if Cisco VPN is uninstalled, I still encounter the same problem.
g.. The IPv6 ICF service is not started.
h.. If I establish a dial-up connection to an ISP, I can ping my IP address across the Internet. It appears that I only have this problem when connecting through an Ethernet interface.
i.. All Microsoft service is applied to XP.
j.. I have two other laptops with near-identical configurations, and I experience no problems.
