I have just installed a server 2012 Standard server acting as a file server in a Workgroup for 6 PC's. I can access server internally by remote desktop connection using 192.168.1.220:3390 (server is on static on .220 and has port 3390 in registry) by enabling the remote option in system properties.
I need to enable remote access for 3 users outside the office using RDP. The office has just an ISP Adtran router, no other internal router is present with again port 3390 being ported by the ISP to the server 2012 box IP internal address. There is no AD services or and Remote services installed at this time.
I WAS able to do a RDP session to the server from outside the office, and I did the updates available for the server, rebooted, and now, I CANNOT rdp from outside the office,, really ?
The 2012 server was purchased with 10 CAL's but the client does NOT want to use AD, DNS, DHCP or and facet of AD, simply a workgroup server for QB file storage, and file storage.
Need specific help on what to setup, links are ok to other sites, but that's not really helping me. Thanks !
