If you have implemented Tachyon Server on an IIS server that has previously been or is currently used by other applications then there may be other Web Server certificates in the Local Computer's Personal Certificates store in addition to the Tachyon Web Server certificate. In earlier versions of Tachyon it was possible under these circumstances for the Tachyon Server installer to bind to the wrong certificate. The current version contains improved logic for avoiding this problem, but it is still good practice to verify that the configuration is indeed as expected.
To select the correct certificate for the HTTPS binding see the troubleshooting steps for Server installation issues.
Immediately after installation you can only access the Tachyon Portal and the Settings application using the installation account, until additional users have been added and assigned to their roles.
The installation account is assigned the following roles and cannot be modified because it is a System Principal.
This means that one of your first steps after installation is to connect to the Portal using the installation account and add other Tachyon users with necessary roles as described in the Users page and the Roles page.
After the initial configuration of Tachyon users and groups has been performed we recommend that the above roles are applied to one or more other Tachyon users and that the installation account is disabled in Active Directory. It can be enabled later for installation of updates and upgrades.
This approach of having a dedicated installation account ensures the same account is used for all installation activities and has relevant rights on the Tachyon server and in SQL Server. Disabling it makes it more secure than a normal user account. If an ordinary user account is used for installation tasks there is a risk the account may be deleted, causing difficulties for future upgrades or re-installations.
You can either load instructions into Tachyon and create Instruction Sets for them automatically from Tachyon Setup, please refer to Quick Start: Uploading Product Packs using the Tachyon Product Pack deployment tool for more details, or you can load the product packs and create their associated instruction sets by hand.
You will need to deploy the Tachyon client to at least one device in order to use any instructions.
Please refer to Deploying Tachyon clients for guidance on deploying clients to Windows and non-Windows devices.
The Export all feature is displayed on the responses page for a question once it has finished retrieving all its responses. To enable this to work you need to configure the following:
Configure the share:
The Export all feature enables the bulk copying of the entire completed responses for a Tachyon question to a specified network share.
As this may potentially be a very large data set the location must have sufficient disk-space to store the exported data.
To use this feature you must create one or more network shares on the Tachyon Server or other location, and configure NTFS and share permissions as follows. If desired, it can be hidden using a $ at the end of the share name.
Configure the share with Everyone modify access, or the same as the NTFS security.
The share folder needs modify access configured for the service account(s) used by the Tachyon Core application pool on each Response Stack server and the service account used by the Tachyon Consumer application pool on the Master Stack server. By default this account is NT AUTHORITY\NETWORK SERVICE (if the share folder is located on a Tachyon 'all-in-one' server where both the Tachyon Consumer and Core components are installed e.g. Master Stack and Response stack). However, there is another scenario where the share folder is neither located on the same server as the Tachyon Consumer or Tachyon Core components, but on a remote fileserver (like a NAS device, DFS share, etc). In this case, the Tachyon Consumer AND Tachyon Core components will attempt to connect to the share folder as their respective computer accounts, for example <domain>\<computer$>.
Therefore, depending on where the share folder is located, you will need to configuring NTFS permissions for the following:
Alternatively, you can use an AD security group that contains the computer$ account of all your Tachyon Servers.
Include any user accounts or AD groups that would require access to the share.
The preceding are the minimum permissions required. Of course, if your share has more permissions it will also work for Export All. For example, if your share inherits from its parent the Modify permission for Authenticated Users, then this will automatically include permission for local and remote computer$ accounts, so you will not need to explicitly grant the permissions mentioned above.
The following tasks are not essential but may enhance the performance and use of Tachyon in your environment.
You can add an inventory connector to Tachyon that will sync data from a data source to an inventory repository. Typically this connector would be to another system such as Configuration Manager or to Tachyon itself. For more details please refer to the Connectors page. At least one configured inventory connector is required to support management groups.
You can create Management groups to partition your estate into groups of devices that can be managed separately. This is done by creating a management group in the Settings application, please refer to Management groups page and Management groups - tutorial for more details. To synchronize the management groups with Explorer you'll need to add a Tachyon connector, please refer to Tachyon connector for more details.
If you want additional protection for the Switch's certificate then you can change the NTFS security on the Switch's SSL folder as described in Services and NTFS Security.
You should also remove the original copies of the certificate files from the installation files.
The Tachyon Server installer does not support configuration of SMTP credentials, but these can be configured post-installation. By default, Tachyon assumes port 25 and anonymous authentication.
Tachyon stores its SMTP configuration in
After any changes reboot the server or restart the 1E Tachyon Coordinator service.
<configuration> ... <appSettings> ... <add key="smtpHost" value="ACME-EXC01.acme.local"/> <add key="TachyonEmail" value="Tachyon@acme.local"/> ... <add key="2FAEnabled" value="true" /> ... </appSettings> ... </entityFramework> <!-- The settings in the following section can be modified to provide custom port and authentication options for SMTP --> <system.net> <mailSettings> <smtp deliveryMethod="Network"> <network port="25" defaultCredentials="true" userName="" password="" /> </smtp> </mailSettings> </system.net> </configuration>
Microsoft's documentation for the SMTP network section can be found here: https://msdn.microsoft.com/en-us/library/ms164242(v=vs.110).aspx.
When defaultCredentials is set to true, the mail subsystem uses the Windows credentials from the process under which the coordinator service is running to connect to the mail server. In general, this will only work with Microsoft servers, or servers that allow anonymous connections. To use different credentials, set defaultCredentials="false" and add values for username and password (and, optionally, clientDomain ).
To use an encrypted connection, if the server supports it, add enableSsl="true". Change the port as needed, for example, port="465" or port="587".
Microsoft supports parameters named host and From, but these are ignored by Tachyon because the smtpHost and TachyonEmail keys in the <appSettings> section take precedence.
If smtpHost is set to empty (blank) in a config file then email is disabled for the corresponding feature.
The Two-factor Authentication feature requires email. Therefore if smtpHost is set to empty, then the 2FA feature must be disabled by setting <add key="2FAEnabled" value="false" /> in the <INSTALLDIR>\Tachyon\Coordinator\Tachyon.Server.Coordinator.exe.config file.
Finally, reboot the server or restart the 1E Tachyon Coordinator service.
2FA is optionally disabled (enabled by default) in Tachyon Setup: Active Directory and email screen. If you need to change this after installation, then you need to edit the setting <add key="2FAEnabled" value="true" /> in the <INSTALLDIR>\Tachyon\Coordinator\Tachyon.Server.Coordinator.exe.config file.
If enabling 2FA, please refer to Requirements: Two-factor Authentication Requirements and Requirements: Email Requirements.
