Error publishing RemoteApp

Hi All,

I´m configuring RDS on Windows 2012R2. I have two production RDS Servers and I installed one Broker and Gateway Server and two session Hosts. After creating a collection with two hosts I wanted to add a RemoteApp. On host1 no problem at all, but on host2 I receive following error:

Server.local is not available on the Network. Verify that the Server is available on the Network or remove the Server from the collection.

It´s not possible to publish a RemoteApp on that host. Does anyone has an idea?

Thanks.

Regards,
Dirk
