Exchange Proxy NTLM Authentication failure when iApp strict updates is disabled initially and then turned on. NTLM authentication fails with STATUS_NO_LOGON_SERVERS.
Any service using NTLM authentication will be disrupted.
The Strict Update option in the iApp is modified.
Restart ECA and NLAD modules to work correctly again. To do so, run the following commands: bigstart restart nlad bigstart restart eca
NTLM authentication now works as expected when Strict Update in the iApp is modified.
