Custom RemoteFX RDS Farm – Stress test 2 – How many users per server?

This entry is part 5 of 5 in the series Custom RemoteFX RDS Farm

Its looking like we got our sizing for our custom RDS servers right and we may well have answered (at least for own internal use) ‘how many users can you get on a RDS server?’. The video shows our RDS farm under normal load with 24 clients remotely logged in (excluding the admin session I was using) with the CPU… Read more



Moodle Error, new users LDAP and SSO (NTLM)

After recently setting up a Moodle install (hosted on IIS on Server 2008 R2) with SSO (LDAP server based (good old Microsoft AD) with NTLM looking after things) we found that any new users were getting this error message appearing.

Custom RemoteFX RDS Farm – The Intro

This entry is part 1 of 5 in the series Custom RemoteFX RDS Farm

Sufficed to say budgets are still tight for schools and nothing chews through the budget more than replacing a computer room full of PCs. One alternative has always been to convert the PCs in the room to ‘fat thin clients’ with a small OS (say Windows Thin PC) and hook them up to a Terminal Server/Remote Desktop Services Farm.

Axel M80 thin client – nice for the office not so sure about the classroom

A little while ago the guys at Axel let me borrow one of their M80 thin clients to try out with Citrix VDI-in-a-Box and also Microsoft RDS (Server 2008 R2) and I’m happy to say I can easily see this as a good thin client to use in the office although I have my reservations about use in classroom.
