Server CAL licensing

Bohdan Reptak 21

I have 2 networks with 2 domain controllers. Each employee has 2 PCs connected to each network and 1 user name for each domain. UserA for domain A and UserB for domain B. there are 100 employees. How many CALs do I need? 100 or 200? I think 100 CALs enough because I have just 100 employees?

A Windows Server CAL is a license that grants access Windows Server. CALs are used in conjunction with Microsoft Windows Server OS licenses to allow Users and/or Devices to access and utilize the services of that windows server

User CALs allow a single user access to Windows Server from an unlimited number of devices

Device CALs allow an unlimited number of users to access Windows Server from a single device

I understand the difference between User and Device CAL. So, how name user CALs I need in my case?

I think CAL is for a Client Access License. So, I have 100 employees (client) it should be 100 CALs for the entire organization? Where I am wrong?

In your case with what you spec'd it doesn't matter Device or User
If User Cals then one per user per server = 100 X 2
If Device Cals then one per client device per user = 2 X 100

Not sure what you're asking here? With what you spec'd it doesn't matter Device or User Cals
If User Cals then one per user per server = 100 X 2
If Device Cals then one per client device per user = 2 X 100

Is it the same situation I have? 1user connected to 2 networks or this is 1 user connected to 2 servers? I spoke to a Microsoft representative from INSIGNT.COM and she told me that I need just 100 User CALs, but she never wrote it on paper. So, that is why I am confused.

Its like this since you have both two devices per user and also two different servers to connect to.

User CALs allow a single user access to Windows Server from an unlimited number of devices

Device CALs allow an unlimited number of users to access Windows Server from a single device' '
If User Cals then one per user per server = 100 X 2
If Device Cals then one per client device per user = 2 X 100
