I have opened port 13 in firewall in outbound direction. I have a packet filter that allows port 13 in both TCP and UDP in both directions in my ISA server. The client is running firewall client. When I try to ping the time server using the atomic sync utility, I get an error which says port 13 is not accessible. Can anyone help me Thanks.
