Our hardware dept. was messing with DNS settings and now the environment won't start.  I get

OpenDBFile2 error is Unable to communicate with database driver process (99).
  Additional information is 1167.

I know it's a database communication issue but when I got to start the listener I get:  lsnrctl:  File cannot be found

In $ORACLE_HOME/bin, lsnrctl is not present like it is on our other app server.

Am I looking in the wrong place?

Lawson is taking forever to get back to me.

Thanks in advance.

the command to start the default listerner is:

lsnrctl start

The files it looks at are in $ORACLE_HOME/network/admin

There should be a listerner.ora and tnsnames.ora file located in that directory (unless you're not using a tnsnames.ora file and using a names server).

If the files are there and your listener starts (could already be running) type

tnsping service_name and see what it returns.

e.g.

LAW9PROD>tnsping law9prod.world

It should return your database connection and ip address.
