have others experienced the same thing.

server machine 1 = windows 7, used as an application server. windows 7 firewall application exception 'inbound' rule added. in this case, server application was 'microsoft sql server, named instance, using port 62718'. servers ip# = 1.2.3.4 (as an example)

client machine 2 = windows 7, used as an application client. windows 7 firewall turned OFF.

no routers between these two machines. its a peer to peer network.

first test (at client machine 2):

telnet 1.2.3.4 62718 fails to connect
portqry.exe test to same ip # and port number reports 'filtered' (meaning the port in question is being blocked by some firewall)

second test (at client machine 2):

turn OFF firewall on server machine 1.
telnet 1.2.3.4 62718 works just fine (telnet session established)
portqry.exe to same ip# and port number reports 'listening' (meaning the port is open and is able to listen for client connections).

evaluation of tests 1 & 2:

apparently when one creates an 'application' exception inbound rule using windows 7 firewall on an application server machine DOESNT WORK AS IT SHOULD!

final test 3:

on server machine 1 - application server, windows 7 firewall, turned back ON. this time i added a new rule that specifically opened port number 62718 (not an application exception in-bound rule, but instead a port exception in-bound rule).

on client machine 2 -
telnet 1.2.3.4 62718 works just fine (telnet session established)
portqry.exe to same ip# and port number reports 'listening' (meaning the port is open and is able to listen for client connections).

evaulation of test 3:

again what seems to be a confirmation that windows 7 firewall on a windows 7 server machine, seems to not to work with application exception in-bound rules. but does seem to work properly with port exception in-bound rules.

DO ANY EXPERTS HERE have additional insights here?

thanks
