Terminal server considerations

Resource limitations. There is a limited amount of memory, CPU capacity, and other resources (such as handles) that limit the number of clients per machine.

There are client session-configurable parameters that administrators need to be aware of to make sure some sessions do not use excessive CPU or memory.

If you operate without a fail-over mechanism and the system goes down or needs maintenance, then all clients go down.

You are not using all the resources of your client PCs. This is also an advantage as you do not need very expensive PCs or you can use thin client devices.
