RDP Server giving C0000006 for Application Programs

Recently, our RDP Server is having some trouble.

Remote users will use the RDP Server to connect to the Application Server, while users that are in-building, will connect directly to the Application Server.

The issue recently is that remote users, using the RDP Server to connect to the Application Server, will get the C0000006 Exteal Exception Error. When the first user gets this error, the error will spread out to users slowly until everyone using Program#1 and Program#2 get the C0000006 error. Rebooting the RDP Server fixes the issue the majority of the time.

I am not sure of what the issue would be that would be causing the C0000006 error for these two Programs (they speak with one another), but usually the first precursor to this creeping up on users are Program#1 and Program#2 showing up blank in Task Manager like so ---> RDP Server C0000006 precursor.png

I know this is a long shot, but any idea what may be causing this? It seems like the communication between the RDP Server and the Application Server. IT would love to fix this issue on our end, but if it is in fact a programming error, it is the 3rd party consultant's programming fix, and must be dealt with by them.

Thanks!
