10g application server
64 bit , windows server 2003 R2
1. Oracle Infra Installed successfully ( i checked EM it was "UP")
2. When Installing Application Server , @ step when putting HOST and PORT (tried both 389 636, host name is correct) getting error --> Error Retrieving port , make sure OID, LISNR configured !!!!!+
after exploring more things , i found -- when i open EM and go to -ports , Gettin "500 Internal Error"
, also when i tried to set up OID , it was saying - Server is not Running
