If you try to map a drive to a Sharepoint document library, you may get the following:
Error code: 0x80070043 The network name cannot be found
In addition to making sure the WebClient service is set to Automatic and is Started, you should also check the following registry key and make sure it contains this value:
Value Name: ProviderOrder
This is what worked for me and I can now map a network drive to my Sharepoint document library.
