Using html5 Portal for RDP not working with RDP Farm?!

GernotMeyer

Hi all,

we moved our Terminalserver from 2012 to 2019 Server and also extended to a RDP session host farm.

It seems that the html5 Portal only works if the session broker chooses itself for session hosting. Otherwise only "Socket broken" is shown up.

It should work in general or not?

Thanks for hints

Gernot

    Hallo Gernot,

    HTML5 remote access is very resource-intensive.  Depending on the UTM hardware, I wouldn't use it for more than one or a few concurrent connections.

    Cheers - Bob

    I agree with Bob on that - I've tried it before, and it was a nightmare to do anything with RDP stuff.  It was not efficient by any means even for my home use.  I found VPN to be much better for any need to be connected to the internal network.

    Hi all,

    thanks for answer.

    HTML5 is only for people that need urgent access. Right. But it is VERY helpfull and so it is needed and it doesn't work any more!

    And: No. UTM is virtual (I never use physical HW if possible) and performance is OK.

    Best Gernot.
