An instance of DeviceLock Enterprise Server running under Windows Server 2008 R2 does not receive any information from Windows 7 clients, while Windows XP clients with the same data transfer configuration send their data successfully.
This known issue is caused by the new authentication algorithm used in Windows Server 2008 R2.
1. Upgrade your instance of DeviceLock Enterprise Server to version 188.8.131.52997 or a higher one;
2. If the upgrade is not an option, the issue can be resolved by creating the "SecurityLevel" DWORD type value on computers with DeviceLock Agent, either using the attached .reg file, or manually:
