I have a MacBook intel duo core 2 gig book. Prior to the recent firmware upgrade I was able to access my company's mainframe (java ica connection center) computer. After the firmware upgrade I am no longer able to access it. Whenever I try to log on I get an error stating: The connection failed: java.net.SocketException also in the details I get: java.net.SocketException: Socket is not connected at java.net.Socket.getInputStream(Socket.java:764) at com.neoteris.NeoterisSocket.getInputStream(Unknown Source) at com.citrix.client.module.td.tcp.TCPTransportDriver.u(Unknown Source) at com.citrix.client.module.td.TransportDriver.run(Unknown Source) at java.lang.Thread.run(Thread.java:613) I'm not sure if the firmware upgrade was the source of this issue, or if it was coincidental. Any suggestions?
