Session Disconnect Behavior on Windows Server 2019, 2022, and 2025 with vSpace Pro Enterprise Edition
Overview
Customers deploying vSpace Pro Enterprise Edition on modern Windows Server platforms (2019, 2022, and 2025) may encounter session disconnect issues related to Microsoft Remote Desktop Services (RDS) licensing requirements. This article explains the root causes, Microsoft licensing prerequisites, and best practices to ensure uninterrupted user sessions.
Issue on Windows Server 2019: 60-Minute Session Timeout
Symptom
vSpace Pro sessions on Windows Server 2019 may automatically disconnect every 60 minutes without warning.
Root Cause
This behavior is due to Microsoft licensing restrictions when using RDS 'Per User' CALs on Windows Server 2019 without an Active Directory (AD)/Domain Controller (DC). This limitation affects both vSpace Pro and native RDP sessions.
Behavior Matrix: Windows Server 2019
Connection Type | Cal License Type | No AD/DC | With AD/DC |
vSpace Session | Per User | Disconnect after 60 min (no warning) | No restriction |
Per Device | Disconnect after 60 min (no warning) | No restriction | |
RDP Session | Per User | Gets 60-minute warning & disconnect | No restriction |
Per Device | No restriction | No restriction |
Recommendations for Windows Server 2019
Use Active Directory: For reliable user session management, deploy an AD/DC environment.
Required CAL Type: Use 'Per User' CALs in conjunction with AD.
Avoid Local Users: If using local accounts only (no AD), be aware of unavoidable 60-minute disconnects.
Workarounds (if AD/DC is not available):
Educate users to manually reconnect after disconnection.
Enable Auto-Login on thin clients with stored credentials to allow automatic session recovery.
Note: If AD/DC cannot be implemented, consider using Windows Server 2016, 2022 or 2025 as these Operating Systems do not have the mentioned restrictions.
Updated Compatibility: Windows Server 2022 & 2025
Microsoft has removed the 60-minute timeout restriction starting with Windows Server 2022.
Behavior Matrix: Windows Server 2022 and 2025
| Connection Type | CAL License Type | No AD/DC | With AD/DC (AD User) | With AD/DC (Local User) |
| vSpace session | Per User | No restriction | No restriction | No restriction |
| Per Device | No restriction | Disconnect after 60 min (no warning) | No restriction |
Conclusion
To avoid session interruptions when deploying vSpace Pro Enterprise Edition:
Use Windows Server 2022 or newer where possible.
Implement AD/DC if remaining on Windows Server 2019.
Understand Microsoft RDS CAL limitations to make informed licensing and deployment decisions. Use 'Per User' CALs for vSpace Pro deployment.
