I am a Domain Admin. I work with 20 domains and have to RDP login to servers on any of them. I usually only get the hostname to work with rather than an FQDN. Using an RDP manager was still inefficient, not to mention annoying.
So I wrote a GUI based powershell script that does the following.
1. Finds FQDN given a hostname. [wrote a custom function to return FQDN from any input]
2. Creates a PScredential object based on the FQDN (Using saved credential on disk stored in encrypted form) [Wrote a custom function to do that too]
3. Uses cmdkey to create an mstsc cached credential and launch RDP.
The issue I face is below. On some servers (not all of them), after clicking OK on the legal notice window, the profile starts loading and then I get this prompt. When I click ok, it logs me off. I dont know how to get around it. According to my research
so far, this is caused because I am trying to pass optional parameters through my MSTSC request. But I don't see how it happens as i have not coded for it. This is where I need help. How to suppress/avoid/work-around it.

[The GUI basically collects the Hostname and calls the function below]. Its pretty straight forward.
