Windows 10 patch MS16-072 / 3163622 / 3163018 can break Smart Office *WORKAROUND*

A couple of months ago I logged an issue with Xtreme regarding Smart Office client being unable to communicate with the Smart Office server.  This has become a more significant issue with the Windows 10 anniversary edition also breaking JScripts running within Smart Office.

Today I have received a suggested workaround from Infor now to resolve the issue of windows updates stopping Smart Office loading.  I've tried this on a couple of sites and it appears to address the issue.  The workaround is:

1. Download IIS Crypto 2.0 from Nartac.
2. Install this on the PC
3. In IIS Crypto 2.0 on the Cipher Suite tab (1), untick the TLS_DHE_RSA_WITH_AES_128_CBC_SHA Cipher (2) then click Apply (3):

4. Reboot the PC.

Smart Office should now load correctly.  I've tested this against multiple sites and multiple versions of Smart Office and all the Smart Office instances that were not working now do work.

Unfortunately this does not resolve the JScript issue :(

    Try this solution.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\Diffie-Hellman]
    "ClientMinKeyBitLength"=dword:00000200
