symptoms
occasionally ping request times out
about every 5 minutes
especially during posts
clears up after 5 to 10 minutes
ping succeeds if attempted from a different machine
even though a route leg is blocked on the failing ping
ping from a specific machine seems to be blocked

Theory
may be windows server firewall on the target machine is programmed to stop denial of service attacks and may wrongly interpreting the traffic and hence block the ip temporarily...

few useful commands
ipconfig /renew
will get a new dynamic ip address
ipconfig /flushdns
flushes dns entries
tracert target-computer-name
gives the route and the internal ips
ping target-computer-name
ping and see if the ip is reponsive

This may be linked to the verizon wireless card as well
This may be linked to the verizon wireless card as well
Apparently verizon servers are doing something funky and may need resetting once in a while by removing and reinserting the sim card!!!
I have done it this morning and so far so good. I will post an update.

Another weird behavior
this seem to happen with ie mainly. Chrome seem to work fine. it happens on my verzion card. It happens at home on wifi. is it tied to my PC?? some virus may be?? it doesn't happen with Deepak who is using chrome on his mac!!
On my laptop it doesnt happen with chrome? what gives? in fact when it locks up on ie, ping fails as well. But it seem to work on chrome and when it works on chrome ping seem to clear itself as well!!
I am entirely baffled!!
