--------listner issue.....

Question

i am facing a strange problem these. We have an oracle database version 10g release 2. there is a web application which are beign used by around 30 users.
Now the issue is that database is up and running, web application is up and running and is connected to datavase whenever a query is made, but i cannot connect to database using TOAD from another machine to my DB Server.
The database sid is orcl, and here is the entry on my laptop , tnsnames.ora file which toad used to connect to server but it is not connecting at all. instead it gives me an error
ORA-12154 TNS: could not resolve service name....
ORCLS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.16.103.109)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
i dont understand why this issue is there , because my webapplication is accessing the same database and has connected fine without error.
Urgen help required.
Regards

ORCLS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.16.103.109)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = orcl)
ORCL1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 150.236.161.57)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
This is the entries in my TNS Names file.THe TNS Names files is of Developer as i dont have the oracle client installed. The thing is that it was working fine for around 8 months, but now for last 2 days its not working ..
Even i cannot connect from .
cmd-->
sqlplus
-> username@orcl or orcl1
it gives tns names error here the same one..
any suggestions.
