Can PCs with working telnet sessions ping the i? Yes - full
connectivity as always before. No changes have been made to anything on
our network in Years. Makes you wonder if/when this will happen again?

Can PCs with working telnet sessions ping the i?
By cannot ping the i do you mean it resolves the name of the i to an IP
address and tries to ping that IP address and fails? For example, if I
try to ping asfd9dkd98f878fsadd813.com I may ping request could not find
the host. But if I try ibm.com it may then say Pinging ibm.com
[129.42.38.1] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 129.42.38.1:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), This doesn't
necessarily mean that all of ibm.com is down. It means that the network
people block pings. The uninitiated often do this because they read
somewhere that pings can be used to mount a Denial Of Service attack and
haven't read all the methods of still allowing ping without being
exposed to DOS attacks.

The ISeries cannot ping these certain PCs on our network. Those same
PCs CAN ping all the Windows servers around the network, but they CANNOT
ping the IP address of the ISeries ??

HELP
Experiencing really strange conditions. From our local as well as
remote locations, our Mochasoft telnet client will NOT CONNECT. Yet,
this is NOT on all PCs. There are some at the local site, and some at
the remote site which remain connected and working!
In addition, I am able to ping to and connect to these PCs (both local
and remote) which are NO LONGER able to get the telnet connection to the
ISeries.
TIA
