Hi, I have a Windows 7 Pro 64-bit. When I run ipconfig on my computer, I can see list of multiple IP addresses, one of them is from my gateway modem which is this. Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : gateway.2wire.net Link-local IPv6 Address . . . . . : fe80::9d60:35ae:89e5:b8a9%15 IPv4 Address. . . . . . . . . . . : 192.168.1.73 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.254 When I run Oracle forms server on my machine, the server binds its server socket on this IP address 192.168.1.73. Here is the output of netstat. TCP 192.168.1.73:49240 tequila:0 LISTENING The problem is the client (which is a program running locally) is trying to connect to 127.0.0.1 port 49240 and it is not able to connect. If I try to manually run cmd and run telnet 192.168.1.73 49240, I am able to connect to the forms server socket. So I know the forms server is up and running. It is just it is not listening on 127.0.0.1 - it is listening on 192.168.1.73. If I run the same forms server in Windows XP, it binds itself to the name of the machine. TCP vodka:6203 vodka:0 LISTENING This is good because the client is able to connect. I have a Windows hosts entry that maps vodka back to 127.0.0.1. But in Windows 7, what should I do to solve this issue? My thought are as follows. 1. Is there a setting in Windows 7 so that any server socket will listen to the hostname instead of IP address? 2. Or is there a setup or program in Windows 7 to make any connection to IP address 192.168.1.73 routed to 127.0.0.1. Your help is very much appreciated! Thanks, RH

It is caused by compatibility issues. Please be assure that you have Windows 7 64bit Oracle client. When installing the client, right-click on the installation file and choose “Run as administrator”. Also you may need to install some patches for it. I suggest you discuss in Oracle forums for more assistances.
