java.net.SocketPermission 127.0.0.1:1099 connect.resolve

I have installed our properitary softrware hundreds of times and have gotten this error twice. The first time I had to wipe the machine and re-install Windows XP in order to get around this error. I thought maybe there could be another solution besides taking such a drastic step. Please Help if you can. The error is as follows:

PolarisEngine exception: access denied (java.net.SocketPermission 127.0.0.1:1099 connect.resolve

java.security.AccessControlException: access denied (java.net.SocketPermnission 127.0.0.1:1099)

at java.security.AccessControlContext.CheckPermission(unknown source)

at java.security.AccessController.checkPermission(unknown source)

at java.lang.SecurityManager.checkPermission(Unknown Source)

at java.lang.SecurityManager.checkConnect(Unkown Source)

at java.net.Socket.connect(unknown source)

at java.net.Socket.connect(Unknown Source)

at java.net.Socket.(init)(Unknown Source)

We have been able to determine that the 1099 port is being blocked and is not able to be opened up, but the question is why and how do we fix it.

Hi,Do you have a firewall running that disallows specific ports from being opened for listening?Chris.

Well I asked the Shop Owner repeatedly over phone if he had any firewall software and he said no. I noticed when I had this issue before the computer was running a program called Net Nanny that one time denied access when I was trying to install the java environment. I tried several times to uninstall Net Nanny but could not, so I just re-installed the OS. I was pretty sure in that situation that was causing the problem but wasn't 100% sure. Now maybe he does have a firewall installed on the machine and he doesn't know it.

Would a firewall be the only thing that would deny access to the port?
