DES is a weak symmetric-key cipher. It is recommended that it be disabled. Rationale: By disabling DES, there is a better chance of maintaining data confidentiality and integrity.
Solution
Perform the following to disable DES 56/56 cipher: Set the following key to 0. HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\DES 56/56:Enabled To disable using PowerShell enter the following command: (Get-Item 'HKLM:\').OpenSubKey('SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers', $true).CreateSubKey('DES 56/56') New-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\DES 56/56' -name 'Enabled' -value '0' -PropertyType 'DWord' -Force | Out-Null
