Windows 8 Workgroup connection problem

A quick workaround may be found here:

1 . Open registry editor ( Start search - regedit)
2 . Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Create a new DWORD value with the following properties: NAME: LmCompatibilityLevel
VALUE: 1
4. Restart
5. If this doesn't work, go back and delete the DWORD you created. -- ME (I don't know why you would leave it there if it does nothing to improve the situation)

Also check out the idea of doing the following:

Make sure every system has the same username/password to access the workgroup share without requiring authentication.

Because you're not running Windows 7 Pro, you may have to always enter the username/password, or do so from time to time, especially if you have more than your allotted concurrent connections or the username/password authentication is not working or the usernames and passwords do not match up (Windows)

Remember that the limit for Windows Home Premium on workgroups is related to the number of active concurrent connections and not the number of systems connected to the workgroup. This means you can probably have 10 concurrent connections, whereas Windows 7 Pro will support 20. Run an elevated command prompt and type in: "net config server" (no apostrophes) to find out yours.

Here is an old trick. Can you access the root drive? \\yourshare\c$\ should give you access to the C drive on any system of a workgroup if you are logged in under an administrator account.

Sorry I don't have more for you, but I hope this helps.
