I first posted this in 'Parallels Mobile Device Management' because I didn't find this forum. How on earth is somebody supposed to find this within Parallels Remote Application Server when just browsing the forums? I used urls to connect to my remote machines with the old Parallels (2X) Client which has been renamed to Parallels Client (legacy) and was not updated in the last year. The url looks like this: tuxclient://?External_Launch=YES&ConnType=2&Server=serverip&Port=3389&UserName=username&Password=password&Connect=YES That url still works with the legacy client, but if you use the new client, then the Parallels Client is just started, but it will not connect to the server and the parameters are ignored. Can I still start connections with an url? Is there any information about the parameters on the internet which I may not have found?
