RESOLUTIONTo resolve this problem, do either of the following four options: 1. Exclude the application that has the error occurring from Data Execution Prevention (DEP). 2. Add the /TSAWARE linker option to build your application. 3. Add the /TSAWARE option with editbin.exe tool. - Run Command prompt of Vistual Studio. - Type following command. editbin.exe /TSAWARE <Program file name> - You can confirm that the program is aware of terminal service by following command. editbin.exe /headers <Program file name> : 8540 DLL characteristics Dynamic base NX compatible No structured exception handler Terminal Server Aware 2229865 Change in TSAware Flag Behaviour in .NET Framework 3.5 SP1
