I appreciate it may not be officially supported, but if you google tera1 and View 7, on how to get Tera1 clients working you find many answers all telling you how to re-enable TLS1.0, which apparently is the only thing stopping them connecting since VMWare decided to disable it. I do not need any of the new functionality for audio, video or scanners added in the latest versions, just to be able to connect to a desktop. 

The strange bit is why it stopped working after an upgrade from 7.4 to 7.7 then back to 7.4.

The question I would still like an answer to is does View change something to do with the Cipher suite and how it talks to the AD (AD LDAP?), and if so how can I remove the 7.7 version.
