Network Share not working through Windows 7 home premium

have problem here....

Have a laptop Win7 Home Premium and desktop Win7 Pro. Made sharing config identical on both and cannot access laptop from desktop, but can assess vise versa. At 1 point received the following error: 0x80070043. can access resources from laptop which are in Public folder, but when i try to access anything else (shared few folders), receive error message that i do not have rights to access that location. What can be a problem and a fix for it?

couple of things....don't know if you chked this or not; on both are the guest acct settings the same ( on or off). Have you chked the permissions on the security tab for those peticular shares.

You guys are awesome.  This little patch to the registry did the trick. After an hour and 20 minuets either on hold or transfered 10 times with Microsoft, I find the correct fix here. 

I had the same issue after I was forced to upgrade one of my PC's to Windows 7. I could no longer access the folder shares or printer I had on my Windows 2000 Pro system.  But the Win 2000 system could see the shared folders I setup on the Win 7 machine.  All I got was the bad username or password and sometimes 'you don't have premission to access that folder'.  Microsoft decided the problem was in the Win 2000 PC and wanted to charge me $259 'if' they could resolve the problem.

After finding the right way to search for this problem, I came accros this post and it took 2 minuets to implement and 5 minuets to reboot.  Then I had all my shares back, and both ways.  The only difference was as follows:

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: 3 (should be 1 to work)

My entry was already present and set to 3

After I changed it to the value of 1 and rebooted, all was fine.

YOU GUYS ROCK.  Thanks so much for the post and simple fix that Microsoft should have helped me with.

Now I just have to figure out what I'm going to do when Win 2000 Pro goes end of life on 13 July 2010. Buy another upgrade?

C. Create matching user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and the passwords assigned to each user account can be different; the accounts/passwords just need to exist and match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY SIMPLE ONES . If you wish a machine to boot directly to the Desktop (into one particular user's account) for convenience, you can do this:

Start>Search box>type: netplwiz [enter]

Click on Continue (or supply an administrator's password) when prompted by UAC

Uncheck the option "Users must enter a user name and password to use this computer". Select a user account to automatically log on by clicking on the desired account to highlight it and then hit OK. Enter the correct password for that user account (if there is one) when prompted. Leave it blank if there is no password (null).

Step(s) C seems to be the answer to my problem - trying to share a folder on a W7 Home Premium machine after adding it to an existing workgroup (all XPs) without users having to enter a password.  I'd done all the other stuff and have been looking for days(!) for the missing piece. I now have one user account on each machine with the same password, did the "Uncheck the option 'Users must enter..' etc." steps and can now access the folder from all the PCs without entering user name & password.  I DID have "Turn OFF password protected sharing" checked, though - and when I changed it to "Turn ON" as you suggested the problem seemed to return.  Any change in any of the steps now seems to screw things up, so I'm going to leave it as is.  I guess I'll have to take all this into account when I connect our laptops through the wireless router too. It shouldn't have to be this hard - it just shouldn't. But THANKS for the help; I'm crossing my fingers and hoping it really is fixed.
