[3dem] remote microscopy question

[James Bouwer]

Hi David,
Not sure how useful this is, but it could provide you with a data point. We just updated both our Arctica and Krios support PCs with the Windows 10 upgrade and everything related to 
Rapid is working correctly. I suspect you may have challenges with your institute's firewall rules, which need to allow access to the correct  IP addresses and ports. The ports that need to be opened are listed in the manual. 
Best Regards,
James

After several months and much gnashing of teeth, we got RAPID running again.  At least in part, the RAPID system works by opening a tunnel through a particular port into the PC that actually runs the Artica.  When this port is open, it is possible for a remote user to connect directly to the Artica PC and control the microscope.  RAPID does not appear to need to be running for this to work, but it is the RAPID system that establishes and tests the port tunnel.

THe mechanics of doing this is simply to point the VNC viewer to the IP address of the support machine, but additionally to append "::portNumber" to the address.

I can make sure that it is working (by physically sitting at the Artica PC's keyboard and monitor, resetting some things and doing a test of the remote connection), only to discover later that the connection can no longer be made.  In my case, "later" can be anywhere from 10 minutes to 2 hours to the next day.  In no case has the connection survived 24 hours since we did the upgrade.

We have asked them to look at the various components and troubleshoot.  Again, no-one seems to have any idea what is causing this problem.
