Oracle Database Discussions

Hi All, I am facing issues after I configured Enterprise Manager. I am using OVM on Win 7 and network netting for OVM is NAT.
Basically I am facing 2 issues after configuring OEM. After I start the OEM using "emca start dbconsole" command
1) When I issue "LSNTCTL STATUS" it displays the status after few minutes instead of instant response. And also When I open my SQL Developer and try to connect to my db it does not connect and timeout's (Socket Read Timed out - Vendor code 504)

2) When I put the address in the URL it takes about 10-15 mins and the OEM page shows the below info instead of showing the login screen.
Database Instance: orcl.localdomain

Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.

I have dropped and recreated the OEM respository but am still facing the same issue. When I stop the dbcontrol then issues with sql developer, tnsping and lsnrctl.... works very fine. Am not sure whats wrong, please advise.
