I have found hundreds of such threads across the web and many on this very site, and I assure you, I have read them all... repeatedly! So I will try to detail everything I have done.
My details:
• 3 computers with identical versions of Windows 7 Ultimate installed.
• All have unique login passwords and usernames.
• None have AV’s or firewalls installed/enabled of any kind (I’ll re-add my security when this is resolved).
• My router is not an issue in any way (my issues cropped up after windows changes, and have never been an issue in the years I have had it).
My issue:
• Computer 1 and 2 can connect to and access all shares and files on all 3 computers, while computer 3 can see the other computers on the network, but gets an error when trying to open a shared resource inside.
What I have tried changing so far (all computers are set identically like this now):
• We all left the Homegroup and joined our newly created WORKGROUP.
• All shares on all computers are done as “advanced” with permissions set to “Full Control” for the “Everyone” user (and just for good measure, all other users as well… just for testing).
• In the Network and Sharing Advanced options, file and print sharing, network discovery, and public folder sharing is enabled.
• In the Network and Sharing Advanced options, we have tried both enabled and disabled.
• Local area connection IPV4 properties has “enable NetBIOS over TCP/IP” enabled.
• In the Local Security Policies, Network access: Allow anonymous SID/name translation and Network access: Let Everyone permissions apply to anonymous users are enabled.
• In the Local Security Policies, Network access: Network access: Restrict anonymous access to Named Pipes and Shares, Do not allow anonymous enumeration of SAM accounts, and Network access: Do not allow anonymous enumeration of SAM accounts and shares, are all disabled.
• In the Local Security Policies, Network security: LAN Manager authentication level is set to “Send LM & NTLM - use NTLMv2 session security if negotiated”.
• In the registry, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa\ lmcompatibilitylevel, the value is set to “1”.
• Probably pointless, but in the credentials section of all computers, the usernames and passwords of all the others were saved, just in case (after we found the issue that is).
(I am sure I am forgetting some things, but these are the major ones.)
Now, like I said, all 3 computers are using identical versions of windows 7, and all have nearly identical security and sharing settings. Yet only computer 3 is having issues, while computers 1 and 2 can connect to all computers after typing out the username and password at the prompt. Computer 3 can open the other two computers on the network (no password prompt, but that might be because we entered it before at some point, or cause we later added the UN
W to the saved credentials), but trying to open any of the shares listed inside brings up the error.
I bet this is already complicated enough, but let me add two more things that might help:
• The issues began when we reinstalled Windows 7 on all the machines. Whatever, setting up network shares is always a bit rough at first. But the real issue came when, on the computer having issues, computer 3, we copied over the entire appdata folder from the old windows 7 user account. It was the same version of windows, we just wanted to save old program information… make the fresh reinstall a little more seamless. Not sure how this could cause an issue… but I’ll mention it just in case.
• There is a forth computer I have not mentioned cause I have done nothing AT ALL to this machine yet it connects to everyone. This is a Windows 8 laptop which was able to connect before the mass reinstall and is still able to connect… to everyone. Again, no changes have been made to this machine and it connects as it used to (as all the computers used to).
Please help me with computer 3. My wife and I are fine, but my daughter is unable to watch the vast Disney movies I store for her or the mountain of cartoons my wife stores for her
Feel free to ask any questions... and I am open to any advice or suggestion.
