So which one is correct? Well, they both are, depending on your goals for high availability. The responsibility of license token validation and enforcement falls on the terminal servers in your environment, not the license server.
When a client connects, the terminal server will check to see if the client has been issued a valid CAL, and will handle any necessary subsequent communication with the license server on behalf of the client. License token enforcement is only in effect when your terminal servers are in per-device mode.
Per-user mode terminal servers do not allocate CALs to client; rather they simply check to see if a valid license server exists on the network and if so, will allow the connection. The only weak link here is in the ability to contact a license server. As long as license servers are available, clients will be able to connect. On the other hand, per-device mode terminal servers do enforce CAL allocation and validation.
If a client presents a valid, unexpired CAL to a terminal server upon connection, the terminal server will allow the connection without contacting a license server because the token has been validated by the terminal server itself. Only under the following circumstances will a license server need to be contacted:. Of these instances listed above, only two of them will actually prevent a client connection — either the client has never been issued any CAL for the environment, or the issued CAL has expired.
Of these two remaining conditions, only one requires access to a license server with available license tokens; temporary CALs can be allocated by any license server.
Therefore, there is really only one scenario that you are attempting to protect against — expired CALs. The mode of the license server determines how it is discovered by terminal servers. Enterprise license servers can always be discovered because the license server location is stored in Active Directory. Note: The most important factor with license servers is discoverability.
Finally, Windows Server enterprise mode and domain mode license servers in the same domain will notify each other when CALs are added to their respective databases. Next, you're instructed to print the form and fax it to Microsoft, who will respond with your PIN by fax.
Telephone—In this method, you select your country and are provided with the appropriate customer service number. A representative will take your company information and provide your PIN immediately. After you select your connection method, the wizard asks how you purchase licenses from Microsoft, as Figure 2. If you're a Select or Open License customer, be sure to have your account number available when you attempt to install licenses.
Select the Other radio button if you're not a Select or Open License customer. You purchased your TSCALs through a retail channel and have the paper license numbers included in the package.
After you complete the wizard, you'll be emailed, faxed, or told a character PIN. If you write it down incorrectly, you'll have to call again. To do so, use the licensing wizard in the Terminal Services Licensing application. The license program and connection method you selected when activating the server determines how you obtain license pack codes.
That would have uncovered the problem with installing everything on a domain controller. Likewise, talking with the Active Directory team here at Microsoft back when they were the sole AD experts would have clued us in on the Site concept, and the fact that inter-Site network traffic is expensive.
What did we do right? Windows Licensing White Paper. Easily back up only the information you need System State and LServer folder , including incremental changes.
Must be restored to similar hardware, unless leveraging a universal bare-metal restore option. No backup schedule conflicts with other enterprise backup jobs; archiving is a result of a normal file server backup.
Windows Backup has no centralized management platform; each job must be set up manually. ASR has no centralized management platform; each job must be set up and executed manually. Naturally low-resource utilization of license services makes a great virtualization candidate. Universally restored to any supported virtualization host — no hardware dependency. Flexible backup and recovery options; can still leverage existing backup methodologies. Universally restored to any supported hardware — limited or hardware dependency, bare metal restore.
