To run Abtrac using terminal services each user will need the application files copied to their own individual folder.
Each user cannot use the standard Abtrac Quick Starter installation which installs files to C:Program FilesAbtrac. This would result in the sharing of one application file, and the potential for data to be lost after entry when another user opens the same application. This has happened!
This is because the Abtrac desktop installation is developed in MS-Access and cannot be opened as multiple instances. (It works just the same as a MS-Word document on your server, if more than one person tries to open and edit records using the same instance only one users changes will be saved)
Remote Desktop Services in Windows Server 2008 R2, formerly known as Terminal Services in Windows Server 2008 and previous versions, is one of the components of Microsoft Windows (both server and client versions) that allows a user to access applications and data on a remote computer over a network, using the Remote Desktop Protocol (RDP).
For Terminal Server users the application files must be stored and accessed as per the green scenario below:
After installing Abtrac in the usual way to your server desktop you will need to copy and paste the files from C:Program Files/Abtrac into a unique folder on the server for each TS user.*
The files you need are these ones below:
If you are using desktop shortcuts these will also need to be reconfigured, setting the target of the Abtrac.accdr file to the employee specific folder.
Registry Entries and Terminal Server users
When you install Abtrac on the terminal server for the first time a registry key entry key is created under the following location:
When Abtrac is opened a MS Access check is run looking for the trusted location registry entries for the user who is currently logged in.
When running multiple instances of Abtrac on a Terminal Server each user will need this security key copied as their own registry key setting for their runtime version of Access 2007 or higher.
Terminal Server users without correct registry settings will receive the following message (or similar) when opening Abtrac.
2. The Path value should reflect the folder created for that user (e.g. Server:Users/Employee4/Abtrac).
When Employee4 log in to Terminal Server , his HKEY_CURRENT_USER registry entry should be :
Note that the location for Employee 5 is the same – but the path is different:
(A note about Office 2010. The default install for Abtrac v5 is MS Access Runtime 2007. If you are installing Abtrac with MS Access Runtime 2010 the key location will be: HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0AccessSecurityTrusted LocationsLocation99))
