John, I had already added winvnc4.exe to my list of firewall exceptions; even with the XP firewall turned off nothing works from inside or outside my network.
The port forwarding from outside has been in place all along. I've worked very closely with my IT Dept. since this started. Latest info from IT shows packet tracing results of 4 packets sent & 4 answered between on outside PC and my internal PC running VNC. The last packet comes from the VNC machine back to the requesting outside PC and then things disconnect. No screen activity is apparent on either end. Any other ideas? ***************************** John Klingler Telecommunications Specialist Akron Public Schools 550 E.
