big problem with listener

hi,
I've installed oracle 8.1.7 server with 2 istances
IMM1
IMM2
IMM2 run correctly, but when I started IMM1 I get this error:
ORA-12541:TNS:NO LISTENER

If I stop and restart the listener IMM1 run correctly again, but when I change connect IMM1 run down again.

I run this query:
SELECT SID, SERIAL#, USERNAME, STATUS
FROM V$SESSION

when IMM1 is up the STATUS is INACTIVE

listener.ora:

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = srvimm)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\ora81)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = imm1)
(ORACLE_HOME = C:\oracle\ora81)
(SID_NAME = imm1)
)
(SID_DESC =
(GLOBAL_DBNAME = imm2)
(ORACLE_HOME = C:\oracle\ora81)
(SID_NAME = imm2)
)
)

The status of listener is:

LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=srvimm)(PORT=1521)))

Someone could help me???

Thanks

Use net8 utility to test the IMM1.
and/or do connect user/pwd@IMM1

I tested IMM1 with net8 but I get same error ORA-12541 but if I stop and restart listener IMM1 run correctly with net8

Do you mean that you get TNS-12541 whenever you connect to IMM2? What is the status of the LISTENER after failure? What appear in $ORACLE_HOME\network\log\listener.log?
