Time someone starts reading...
Very easy to reproduce, although it generates a clearer message in 9.2:
C:\Documents and Settings\frankbo>lsnrctl start

LSNRCTL for 32-bit Windows: Version 9.2.0.4.0 - Production on 25-JAN-2004 14:56:
13

Starting tnslsnr: please wait...

Service OracleOraHome92TNSListener already running. TNS-12536: TNS:operation would block
  TNS-12560: TNS:protocol adapter error
   TNS-00506: Operation would block
    32-bit Windows Error: 997: Unknown error

You have a process running on the same port, hence the "Operation would block"

Could it be your listener is alredy running?!? Do a netstat -n and check if there's a 1521 port listening
