License Server administration without a console

There are several administration procedures that you can do without using the Citrix Licensing Manager. We recommend that you use the console whenever possible. This article describes the procedures required if you are unable to use a console.

  • Configure the Vendor Daemon log (CITRIX.log) from being overwritten
  • Customer Success Services renewal files
  • Delete license files
  • Disable the domain name truncation on Windows
  • Find renewal and maintenance expiration dates

You can use the licensing management tool on to download, allocate, install, modify allocations, return, and hide licenses. For more information, see Manage Licenses at My Account.

You can use licensing commands to perform licensing tasks. For more information, see Licensing commands.

Configure the Vendor Daemon log (CITRIX.log) from being overwritten

In License Sever version 11.16.6 build 34000 that does not support the License Administration Console, you can configure the Vendor Daemon log (CITRIX.log) from being overwritten as follows:

  • Go to LMGRD_LOG_FILE location (HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\FLEXlm License Manager\Citrix Licensing\LMGRD_LOG_FILE) in your system.
  • Add a + in front of the path. For example, example: C:\Program Files (x86)\Citrix\Licensing\LS\Logs\lmgrd.log changes to +C:\Program Files (x86)\Citrix\Licensing\LS\Logs\lmgrd.log as seen in the following image.

Customer Success Services

After you download your Customer Success Services renewal license file from, you must add it to your License Server. Copy the Customer Success Services renewal license files to the same directory as your existing license files and reread (using lmreread) the license files. For more information about the lmreread command, see Reread license and options files (lmreread).

By default, this location is:

C:\Program Files\Citrix\Licensing\MyFiles on a 32-bit server

C:\Program Files (x86)\Citrix\Licensing\MyFiles on a 64-bit server

After you add the renewal license to your License Server, the license automatically unlocks any subsequent versions of the product released during the Customer Success Services period.

To separate your licenses (two different licenses on two different servers):

  1. Select a second server and install the License Server software.
  2. Go to to modify and allocate your original licenses into two new files. These original licenses are contained in your current license file on the original License Server.
    • Allocate licenses to your first License Server for your first deployment.
    • Allocate licenses to create another license file for the second License Server for your second deployment.
  3. Generate and download your Customer Success Services files and then copy them to the server to which you want them applied.
  4. Point all computers to the License Server running the version of the Citrix product you want them to use. For information about pointing your Citrix product server to the License Server, see your Citrix product’s administrator guide.

Delete license files

When you upgrade your edition (for example, Standard to Advanced, or Advanced to Premium) you receive new Citrix product licenses. You can allocate these licenses to one or many Citrix License Servers through license files created at Rescinded licenses must be deleted from License Servers within 90 days of new license purchase. Deleting the licenses enables:

  • License asset management
  • License compliance
  • Delete unnecessary alerts from appearing in the management console

Considerations when deleting files:

  • Incorrect removal of license files might inadvertently lower the total licenses available.
  • Place any new license files on the License Server before deleting any licenses.
  • Delete a license file only when all INCREMENT lines in the file are obsolete or unnecessary. For example, every increment line was replaced with a new license because of an upgrade.


Never delete the options file (citrix.opt) or startup license (citrix_startup.lic).

  1. At the License Server, open the Services panel and stop the Citrix Licensing service.
  2. Open the Windows Explorer and navigate to where the license files are stored. By default license files are stored in:
    • C: \Program Files\Citrix\Licensing\MyFiles on a 32-bit server
    • C: \Program Files(x86)\Citrix\Licensing\MyFiles on a 64-bit server
  3. Back up all license (.lic) files.
  4. Using a text editor (we recommend Microsoft WordPad), open each license (.lic) file and identify one or more obsolete license feature INCREMENT lines.
  5. Ensure that all increment lines are obsolete or unnecessary. See License file format for information about increment lines.
  6. Close the file and change the file name extension from .lic to .old.
  7. In the Services panel, restart the Citrix Licensing service.
  8. Delete the renamed .old file.

Disable the domain name truncation


Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

When you host multiple domains and multiple users who have the same user name on different domains, you can leave the domain name truncation enabled. For example, and If you have unique users on various domains, ensure that the License Server does not truncate

The License Server detects Citrix Service Provider licenses and enables this functionality.

  1. Locate the registry key:

    For 32-bit machines: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\licenseserver

    For 64-bit machines: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\licenseserver

    Name: UDUseDomain

  2. Set the registry key to 1.

    Data Description
    0 The domain field is truncated. (default)
    1 The domain field is not truncated.
