I'm currently having an issue which began when a user reported they're unable to access RWW because the TS Gateway service was stopped. This is affecting all users.
Following this I checked and the TS Gateway service appeared to be missing which led me to checking the roles in Server Manager where TS role isn't even there.
Subsequently I checked other areas and have tried to reinstall the TS Gateway role where I'm met with the error attached (Problem 2.jpg)
I've rebooted the server and tried again but met with the same error. I have included the log which is generated by this as well.
Any suggestions would be much appreciative.
