Hi I'm experiencing similar problems to this post. Is there a cure? I have a pc with wincc RC v6.2 sp3 hf7 on Windows xp sp3 running with a 256 tag RT licence, please don't ask why, its been here a long time. Until recently we could connect with ultravnc when in runtime from a pc on a different subnet. When we try to change page the screen would freeze and we would have to log out of vnc and then back in to see the next page, or as previously mentioned send ctrl-alt-del to open task manager and this would allow screen update (sending screen update request would not work). I put Hf7 on hoping it would fix the problem but now once I start runtime i lose comms with the machine if I'm on a different subnet. I can run pings to and from the pc from different subnets right up to the point of starting the runtime and then it justs stops. I can still ping and connect if I'm on the same subnet. We have another machine on site using WinccV6.0 RC and a RT licence and don't have any problems at all . Any ideas? Yanto

Are you sure that the WinCC screen also freezes locally? What you describe above sounds like a common known VNC-issue. |

Which version of ultravnc are you using? Same version on both sides? Google ultravnc freeze shows some topics. You could try to reset the TCP/IP stackj: https://support.microsoft.com/en-us/kb/299357 |
