There is nothing built into Patch for Windows Servers (PWS) to allow multiple connections to it. You would need to handle this through RDP.
On a side note, we have been looking at adding a feature for a web based console interface for some time now. It would be a good idea to submit a feature for this to let our Product Owners know customers are still looking for this.
Ok installed and licensed RDA so more users can use it.
Also made a feature request.
Good to hear, I'll mention the request to the PO the next time I see him today.
