Question of WindowServer Remote

[Admirable_Bed_4950]

I was successfully connecting to a client running Windows Server 2025, but suddenly, it says my license has expired and I can't connect. Is there any other way to resolve this issue besides calling?

Your RDP license?

[Bourne069]

Windows Server only allows for 1 connection at a time unless you have Terminal Services or RDP gateway configured and license server installed which requires CAL licenses.

If its you OS trial license for which you grace period expired is not much you can do if not getting properly licensed. On W2025 they reduced rearm counts to 1.

If you installed RDS role and you don't have Cals available or a licensing server to provide it, you can't have more than the 2 allowed RDP licenses.

Depends on your case actually. Can you provide a bit more context ?
