Have had a few questions about Terminal Server through EBS and SBS RWW, so thought I would post a link over to the Microsoft KB on it and include the resolutions from the KB below. While not directly supported by design, here are the workarounds for both EBS 2008 and SBS 2008.
EBS 2008 does not support directly connecting to a Terminal Server through RWW. In larger environments, publishing a large number of connections through the Messaging Server’s TS Gateway may cause a resource spike on the server.
In environments where it is desired to have connectivity through the RWW page, there are several workarounds available:
1. Publish the Terminal Server’s RDP port (3389 by default) through TMG. See http://technet.microsoft.com/en-us/library/cc995085.aspx for more details.
2. Distribute .RDP files configured to use TS Gateway to end users.
3. Add a link for the Terminal Server in RWW. To do this, use the following steps:
<Link DisplayText=”TS” Url=https://<REMOTEURL>/Remote/tsweb.aspx?targetMachine=<TSNAME> _locID=”useTS” />
Where <REMOTEURL> is the FQDN of your RWW server and <TSNAME> is the host name of the internal Terminal Server you are trying to access. For example:
<Link DisplayText=”TS” Url=https://remote.contoso.com/Remote/tsweb.aspx?targetMachine=MyTS _locID=”useTS” />
The Small Business Server 2008 (SBS 2008) version of RWW does support adding a registry key to reveal Terminal Servers in the domain (see http://technet.microsoft.com/en-us/library/cc527532(WS.10).aspx). This registry setting has no effect in EBS.
