SBS 2011 – Remote Desktop Gateway Not Available After Update Reboot?

We are in the process of running updates on our newly migrated to SBS 2011 server.

After the server came up from its post update install reboot every logon attempt came up with a “Remote Desktop Gateway service is not available” error.

We flipped over to the Intel Remote Management Module 3 KVM session to see what was going on (we always open a KVM session to watch the server’s reboot cycle) and found the SBS 2011 CTRL+ALT+DEL logon screen.

So, everything looked normal there.

After logging into the KVM session we tried to log on via RDP one more time and it worked.

A look into the Services MMC in the SBS Native Tools Console’s Computer node turned up the following:


  • Remote Desktop Gateway: Started – Automatic (Delayed Start)

Ah, not to panic then. We just need to be a bit more patient as things come up after that boot cycle! :)

Tutorial, not really.

Here are some pointers though:

DNS: Need DNS A record point to ISP provided static IP for remote.yourdomain.com

+ Need MX record pointing to static IP as well.
+ Need SPF record for domain and ISP domain for e-mail to not be greylisted/blacklisted by others.

Internet gateway/router appliance needs the following ports forwarded from WAN to LAN IP of SBS:

443: HTTPS
987: HTTPS for Companyweb
25: SMTP for e-mail inbound

Optional: 1723 + GRE for PPTP VPN.

We do not open port 80 since it is not needed.
