I have an application that has certain needs to work correctly. This application doesn't support IE 10 and needs IE to displays help information. I am running this on Server 2012 RDS because I found that .Net 4.0 on 2008R2 RDS was not capable of supporting the application in the RDS environment. I would have repeated crashes with this application. It however runs solid under Server 2012 RDS. When I switch it to compatibility mode XP sp3 I loose all network paths for data and do not have any network connection at all. The interesting thing is when I use this from the administrator login only I do not have this issue with loosing network connectivity. I only have this issue when I switch it for the other users. Run as an Administrator does not make a difference. I have research the other issues on 2008R2 RDS extensively before going this direction. I have determined that the .Net 4.0 add on is just not robust enough for RDS and this application. The 2012 server works with this exception of the compatibility mode bug.
Any insights or help would be greatly appreciated.
