So I have a desktop running windows vista home premium and a macbook pro. I have realvnc enterprise server running on the desktop and real vnc view running on the mac book. The problem is when I start up the desktop, after it has been off for a while, I CANT connect to the vnc server and i get a message that says, "network unavailable (51)" BUT if i restart the machine it will work right away and I didn't do anything different. It does this every time and its really annoying! any ideas of how to fix it???? Thank you!
