Windows XP CE Thin Clients Connecting RDP to Windows Server 2019

Question

Will a Windows XP CE Thin Client connect to Windows Server 2019 operating as a Terminal Server? Right now we have several versions of older Thin Clients (XP being the oldest) that connect fine to a Terminal Server operating on Windows Server 2008R2. We are upgrading the Servers and want to make sure the existing clients will be able to connect using the latest available Server OS. If not, what are the options for compatibility (older server OS, upgrade Thin Client OS, replace Thin Clients, etc.)? Thanks

Hi,
There is no exact document confirmed the compatibility of RDS servers and clients but per our experience that lower version of clients will have problems on remoting to higher version of target computer/server.

Some examples for your reference:
1.Below KB mentioned that hotfix is needed when using clients running RDC 6.0 or 6.1 for RD web access.

2.RDP 6 and later is supported with Server 2012.RDP 5.x clients CAN connect if no license server is activated. In this case, Server 2012 RDS does not issue any license to the client, and allows the client to connect at a low encryption level, 512 bits.
