I know this is a "server", but prior to today's updates it was fine for RDP Wrapper.
For the desktop version (Windows 8.1 - 6.3.9600.19628) also stopped working after the update.
Help please. Windows 8.1 - 6.3.9600.19628
I also have the same problem with:

Thanks!

Bom dia a todos!
Estou tendo problemas com o server 2012 r2, (6.3.9600.19628) rodei o rdp, fica tudo verde, por茅m s贸 permite 2 conex玫es simultaneas

Look for GPEDIT settings for RDP, one of those can effect login limits.
when green but only 2 connections, it's often the ini malformed (wrong encoding format or missing last blank line so rdwrap dll ignore it but rdpwrap configuration says yes because it check ini differently and says ok.
