The machine I was having problem with had RDP enabled from a GPO. In the registry, it had the setting set to have RDP disabled. Everytime gpupdate would run, that registry setting would be come valid and kick me out. Once gpupdate was done running, gpupdate could overwrite that setting and allow me to connect once again. I went into regedit and changed:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server entry fDenyTSConnections from 1 to 0, forcing it to always have RDP enabled
Para esclarecer, você precisa mudar:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\fDenyTSConnections
de 1 a 0 , que sempre tem o RDP ativado
