Thanks for your fast reply,
Exactly, AMS Server was not defined on this Client, however IP address of the AMS Server is defined on the installation package ...
I have this error on several Client.
After defined AMS Server with 'aswChAms address_of_my_ams_server', I always have the warnings :
CClient:: PopupThread - GetConnection failed (0x7FFF0021) and POP from Server failed (0x7FFF0021, res timestamp: 0).
So, my AMS Server doesn't see yet this client.
I use 16111 port to communicate betwenn AMS Server and Client, this port needs to be open in both ways ?
Because, my AMS Server isn't in the same vlan that my client.
Thanks,
PS: you know Rouen, it is however not a big place in France !!!
