Cannot ping own IP

My server can ping other file and application servers.  However, it cannot ping its own IP and router.  I have MPTS and TCP/IP v.3 running on OS/2 Warp Connect 3.0.

What's the output from the OS/2 command:

   netstat -r

???

Can other servers "ping" the router?

Use 'ifconfig lo up'

(Note: 'lo' is the first letters of 'LOOPBACK', not "ten".)

'IFCONFIG LO UP'.

I(nter)
F(ace)
CONFIG(uration) utility to set the TCP/IP
LO(opback) interface into the
UP (not "down") status,
to enable TCP/IP "clients" and "servers" to communicate "internally",
rather than communicating to a different host.

Check the output from 'netstat -r'
both "before" and "after" the command.
Post both results here.

Are you sure about this line?
'83' versus '93' ???

> 172.0.0.1 189.5.16.93 0.0.0.0

Are you sure that it is '172' ?

After rebooting, try 'ifconfig lo'.
What is the output?
