NetScaler – One vServer Fits All

by

The NetScaler ‘E’ – or enhancement – releases sometimes contain important or very useful features – when Citrix XenMobile was originally released, it required that the NetScaler use the latest ‘e’ release. One feature of particular interest in the latest e releases is the ability to use a vServer for both content switching AND Access Gateway.

Load Balancing Remote Desktop Gateway with Citrix NetScaler

by

It may seem a bit ironic to use a Citrix NetScaler to load balance plain vanilla RDS, but the NetScaler wasn’t always a Citrix product and it certainly has a thousand more uses than just an Access Gateway appliance. So today we’ll be using it to load balance and content switch our Remote Desktop Gateway server(s). First, I’ll assume that you’ve already got RD Gateway up and working with a publicly trusted cert. Next, we … Read more…
