Windows 10: win 10 refuses to share drive in workgroup

Drive C: on a new win10 laptop is marked Shared for Everyone, read+write+control (because it will hold a webserver and database server that must be manageable from other workstations in the workgroup).

Yet win10 refuses access to a map-network-drive request from File Explorer run as administrator on any win7 machine in the same workgroup.

What an I missing. How do I get past this stumbling block?

Windows 10 Cannot Reach Network Share

I have a situation where a Win 10 PRO PC cannot access file share on a Win 7 PC. Prior to upgrading to Win 10 PRO this PC was Win 8.1 and could access the share in question.

PC1: Win 7 Pro with shared drives A, C, not joined to a domain, homegroup OFF, WORKGROUP,

PC2 Win 7 Pro, joined to a work domain that is it not on, homegroup OFF,

PC3 Win 10 Pro, shared drive C, not joined to a domain, homegroup OFF, WORKGROUP. I did a clean upgrade from Win 8.1 to Win 10 - initially I could mount PC1 A as a drive, but now I get a disconnected error,

All PCs are connected by a simple Telco router. Please take careful note: PRO version of all OSs.

PC1 - can access the files on PC3

PC2 - can access the files on both PC1 and PC3

PC3 - cannot access the files on PC1 (P2 has no shared files/drives). I get the error - MS Windows Network: Logon failure: the use had not been granted the requested logon type at this computer.
I'm using the exact same credentials that I use on PC2 to gain access. One of the recent updates to Win 10 has created a logon problem. Prior to late December 2015 I could get see A,C on PC2 but there were intermittent problems.
Since the last week no access at all. MS has been pushing a lot of updates.

PC3 - If I go to This PC > Network I can still see the old mapped drive but everything is greyed out. It's like there is a cache or something that I can't get flushed.

Any ideas?

 

Unable to share files on Network

Win 10 is more difficult and problematic than previous versions. I have two newer machines now running it, but also have a couple of XP machines I need to share files with on my network.

The file sharing on the Win 10 machines is very unstable...sometimes it works and sometimes it doesn't. Both machines are in the same workgroup, I have set all the parameters on Advanced sharing to the recommended settings, the drives and folders on both
machines are configured for sharing, and I still usually get "Windows cannot access..." when I try to check the C drive on the remote machine, or one of its folders. Sometimes the folders on the C drive will display, but I still get the message when I try
to open them. Most frustrating...did not have as many problems with Win 7; XP was a cinch!

I'm having the same problem. I had it working in the RTM 10240 Win 10 build but now that I've upgraded to the new 105856 build I can't get it to work correctly.\

My opinion they broke something trying to make the OS more secure.

 

Yikes. How do I revert to Windows 7?
