Disabling TLS 1.0 on Server 2012 R2 causes Remote Desktop Management Service to fail to start

-

very basic rds setup on server 2012 r2.  single vm running roles.  everything works fine until disable tls 1.0 on server.

then remote desktop management service fails start error code: 0x88250003.  

service control manager error gives error code: %%2284126211

and see tons of schannel 36871 errors: a fatal error occurred while creating ssl client credential. internal error state 10013.

any ideas?

hi patrick,

thanks post.

disable tls 1.0 change default setting of rdp.

by default, if tls not being used, , setting not enabled on client or on server, remote desktop protocol (rdp) channel between server , client encrypted using rc4 algorithm 128-bit key length. after enable setting on windows server 2003-based computer, following true:

  1. the rdp channel encrypted using 3des algorithm in cipher block chaining (cbc) mode 168-bit key length.
  2. the sha-1 algorithm used create message digests.
  3. clients must use rdp 5.2 client program or later version connect.

if want disable tls 1.0, change rdp security layer start rdms.

for more information, please refer similar thread , article below.
