All ports blocked even though Windows Firewall is turned off
Hi,
This happened recently, all the ports on my Thinkpad (running Windows XP SP3 with latest patches) are blocked somehow, I couldn't telnet to this box from another machine in LAN on any open port (80, 445, etc). I can confirm the ports are open by telnet to 127.0.0.1 locally. Windows Firewall is turned off, its service stopped. I'm fairly sure no other firewall is running (none that I can recognize anyway). Outgoing connection is fine, I can browse Internet or access file shares on other machines in LAN. Any idea how to debug this problem? Is there a tool I can use to find out which program is blocking the request? Thanks |

All ports blocked even though Windows Firewall is turned off
Hi
Computer's Ports are always Open ready to be used by applications. Firewalls Blocks the access to the ports. If the access is not blocked we call it that the port is open. It seems thta something in the way you use the telnet is Not configured correctly. Jack (MS, MVP-Networking). "Jim" wrote in message ...

It includes a stateful firewall that is enabled even when the VPN client isn't. If so, fire up the client and check the "Options" menu and disable it. HTH, John |
