Just stating the obvious here .
Did you try a different browser?? Could be that there's an issue with the browser??
Also, which browser are you currently using and did you try from one of the connection servers and another client computer and browser?
It turned out to be my fault. I set a post script .bat file to change the UserINIT (in Winlogon). So it got rid of All VMWARE in the UserInIt.
The reason for that is when Win 10 opens, it opens with File Explorer launched. One way to get rid of that is to edit the UserInIt reg.
I need another way to stop File Explorer from opening.
