A customer just opened a second satellite office - which for us is the second satellite site. At this and the earlier satellite site we installed a server 2008 r2 to be a Domain Controller, DNS, File server and Terminal server gateway. Each site also has two servers running 2003 r2 required for a third party application. We brought the newest site up last week. I know that before I left, I logged onto the DC locally and verified that I was able to remote to the other 2 servers. We get home, remote to the new site but can't remote from the DC/TSG to either of the other 2 servers. We get the standard:
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
However, I can log onto the terminal server gateways at either of the established sites and remote from there to the 2 server 2003s at the new site - disproving all 3 of the possible errors listing above.
And once in either of those servers, I can remote to the DC. From each of the 3 servers at the new site I can ping the other 2 by IP address and domain name. And finally, from the DC/TSG at the new site, I can remote desktop to the TSG at the main site (didn't bother testing any other connections).
