Slow RDP Connections via Server 2012 Essentials Remote Web Access

-

hello,

i have brand new server 2012 essentials server , i'm having issues remote web access believe, narrowed down remote desktop gateway service. have port 443 forwarded server router, , able access remote web access page, issues arise when attempt connect computer. if click on server (configured use remote desktop, not dashboard) or windows 7 client pc, successful in connecting 20-30% of time. when allow me connect, connection active 10-15 seconds before locking , stating 'the connection has been lost. attempting reconnect session...' connection re-established within 15-20 seconds, work few more seconds before kicks me 'reconnecting.' continues in such cycle indefinitely. on occasions rdp connection not complete , log me pc, receive such errors "there problem webpage," "an error occurred on webpage," "there error on remote computer," or "the rd gateway server temporarily unavailable."

below list of troubleshooting steps have taken far:
- attempted connect multiple computers (server 2012 windows 7 client pc) via remote web access
- attempted manually specify rd gateway server in standard remote desktop connection, bypassing iis/rwa
- attempted connect server via alternate remote method (teamviewer works fine)
- logged onto workstation via rdp directly server (works fine)
- internet bandwidth test (speedtest.net result consistently ~20mb down, ~2mb up)
- updated nic drivers on server
- network service tweaking on server, disabled tcp autotuning, ecn capability, rss, , tcp chimney offload
- restarted services , restarted server
- updated client pc (windows 7 pro sp1) latest rdp client (version 8.0)
- verified mtu setting (1472)

other notes:
- server 2012 essentials oem
- lenovo ts430, xeon e3-1220 v2 processor, 16gb ram
- at&t dsl internet, innsite router

guidance/suggestions appreciated!

thanks,
neil
