I hope you are doing fine.
By now I still have not recovered any information from you regarding remote access to TNG server. As far as we have just few days for configuration the following week, it is required for me to get remote access in advance to make sure that server configuration is correct.
Let me remind that we recommend Win server 2012 R2 x64 as operation system, 300Gbs for each drive C and D. Not less than 8Gb RAM for server and all the latest updates installed. Please, make sure that the server has local(not domain) administrator, which password you will provide me as remote connect credentials.
