I've got a Dell laptop just updated to SP3 and am having issues with ping. From my PC i can ping everything on the network, even my own IP address. But a ping request from another pc to mine times out. I ran a port sniffer and all ports are disabled. Did the regular windows firewall checks enabled echo response enable ICMP, turned it off, enabled everything. Reset the TCP/IP stack no change. created a blanket policy for icmp no change. anybody have any ideas how to get the ports open. I have Nortel WMS server loaded on my laptop could that have anything to do with the ports being blocked?
