Environment: Windows 2000, Oracle 8.1.6

We had this windows 2000 server/oracle database working fine. Now I found my oracleServiceDbname stoped and listener service also stopped and are not starting - Message I am getting is 'Access is denied'. I/IT have full access and both get the same message.

I tried to login from svrmgrl getting getting this protocal adapter error.

C:\Documents and Settings\singhd>set ORACLE_SID=gen0301p
C:\Documents and Settings\singhd>svrmgrl

SQLNET.AUTHENTICATION_SERVICES= (None)

USE_DEDICATED_SERVER = ON

NAMES.DIRECTORY_PATH= (TNSNAMES, LDAP, ONAMES, HOSTNAME, NIS, DCE)

Listener.ora:
-----------

LISTENER =

(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\oracle\ora81)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = dbname.domain_name)
(ORACLE_HOME = F:\oracle\ora81)
(SID_NAME = dbname)
)
)


Please help.
