RDSH A will never use RDL server 2, while RDSH B will never use RDL server 1. This is easily achieved by configuring RDL server 1 as the licensing server on RDSH A and RDSL server 2 as the licensing server on RDSH B. For example, suppose you have 2 RDSHs (A and B) and 2 RDL servers (1 and 2) and you want RDSH A to use RDL server 1 and RDSH B to use RDL server 2. This way it’s much easier to determine which RDSHs should use which RDL servers. How can an RDSH know which system to use as its licensing server? Well, in the past Terminal Server (TS), the predecessor of RDSH, could discover such a licensing server automatically, but now an RDSH must be configured explicitly to use a set of licensing servers. Now, let’s assume every RDSH needs such an RDL server. If you are a cheater, don’t care about user friendliness, don’t need to have more than 2 users access the system at the same time, let your users be administrator on the system (except when you configure the system so normal users can use administrative sessions) and don’t need or care about the restrictions, well, OK, than you have an exceptional situation where you don’t need that license server. Some things can’t be achieved during such a session.By default administrative sessions are only possible for administrator accounts, but not for normal user accounts.Only 2 concurrent administrative sessions are allowed on a certain system, so in almost every case this limit is way too restrictive J.That’s not a user friendly way, isn’t it?.You can get an administrative session by starting Remote Desktop Connection (RDC mstsc.exe) with the admin switch, so just like this:ĭo not try to give your users access through administrative sessions, because An administrative session is a session for administrative purposes and doesn’t require a license. One exception is when you only use administrative sessions on your RDSHs, but there are not many scenarios out there where you need to set up RDSHs for administrative sessions only. When you use Remote Desktop Session Hosts (RDSHs) you need a Remote Desktop Licensing (RDL) server to take care of licensing needs. What you should know about Remote Desktop Licensing first
Note this is not a complete manual though, it just explains the things you should know before discussing the actual issue.
But let’s start with some background information first, just to be sure you have the necessary knowledge about this topic.
This article explains what happened and how to fix the issue. attributes of an AD user can’t be updated by the licensing server.
This event is talking about a problem, i.e. It seems in some scenarios users accessing a Remote Desktop Session Host (RDSH) don’t get a license from a Remote Desktop Licensing (RDL) server and an even ID 4105 is logged on the RDL server.
