[YangHaoi]

1.Line number 124 In mimispool.c

if more than 2 RDP users active, mimispool will be run CreateProcessAsUser more.Like this image:

2. Fix，Use API ProcessIdToSessionId() Get SessionId ：

DWORD processId = GetCurrentProcessId(); 
DWORD pSessionId = 0; 
ProcessIdToSessionId(processId, &pSessionId);
......
// Check Current SessionId
if (Session[i].State == WTSActive && Session[i].SessionId == pSessionId)
{
....
}
