If we disable RC4 encryption in GPO Domain Level, it is not allowing users to login.
Issue: Old AD, RC4 encryption is there, client reported stating it is weak and to switch to AES.
We enabled AES encryption >> tested >> all normal.
We disabled RC4 encryption >> we couldn't connect back to environment (we use Client's Citrix for RDP), we were unable to connect. Reverted GPO settings, enabled RC4, and we were able to login.
How to disable RC4 safely without any issue for user login.
Please assist.
