Hello experts,
Hope someone can help with this wierd issue. I have googled and tried many tricks but so far they all have failed.
After Windows updates on 12 Jan 2016, our Win2K8 R2 server is rejecting RD connection.
The error is:
This computer can't connect to the remote computer.
Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator.
In the event log, for every rejected connection attempt, a Schannel Event ID 36888 is logged, with
The following fatal alert was generated: 51. The internal error state is 602.
I understood this is TLS1_ALERT_DECRYPT_ERROR (51)
One interesting fix we tried was to delete the Remote Desktop certificate. http://visualplanet.org/blog/?p=157
When this is performed, the server will accept RDP connection for just once, and the certificate is recreated as expected. Afterwards, the server will reject RDP connection again until the certificate is re-deleted.
Any help would be much appreciated.
Thanks
