When installing SharePoint 2010 on a client site recently I came across an issue where half through the SharePoint configuration it hit an error with FIPS validated cryptographic algorithms. After some investigation it turns out the client had FIPS algorithms configured on the server. To be able to configure SharePoint 2010 onto the server you need to disable the FipsAlgorithm in the registry.
Step 1: Open Registry Editor on the server
Step 2: Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\LSA\FipsAlgorithmPolicy
Step 3: Double Click Enabled property
Step 4: Change the value from1 to 0 and select OK.
Step 5: Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\LSA\FipsAlgorithmPolicy
Step 6: Double Click Enabled property
Step 7: Change the value from1 to 0 and select OK.
Step 8: Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\FipsAlgorithmPolicy
Step 9: Double Click Enabled property
Step 10: Change the value from1 to 0 and select OK.
Step 11: Reboot machine and re-run the SharePoint configuration.
