Exchange 2013: A fatal alert was generated and sent to the remote endpoint Windows SChannel error state is 10 [Pending]
Posted by Teruin laurent sur avril 9, 2014
Today from two fresh Exchange 2013 SP1 (Version 15.0 (Build 847.32)) installed servers i have to cope with this error message:
A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 10.
Because this error message is almost laconic is it a little bit difficult to find the reason.
After searching on the Web I found nothing relevant. Find a workaround (no proud of this…)
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL : EventLogging=0
In another server I try this Group Policy Editor (run: gpedit.msc), Computer Configuration > Administrative Templates > System > Distributed COM > Application Compatibility and enabled « allow local activation security check exemptions » Disabled.
Work and a little bit better.
