Windows 7 Help , new Win7 system will not work on the network correctly.... details in post!!

[jyujinkai]

Hi there....

I am having a terrible time trying ot get my new windows 7 system to work with my other devices on the network. The real kicker is that my other windows 7 system works fine.. I just can nto get this new one to work correctly for some reason.

Basically I wish to have all the network passwords removed so my linux box running ubuntu and mu media server / player and stuff can see network shares on the new windows 7 system. The problem is that when ever it tries to connect it is prompted for a password, but nothing will work.

I have tried guest accounts, tried no passwords.. pretty much everything I can think of so I am coming to you in the hope that you guys will have some idea... I think after all the fiddling I have just done something totally wrong...

Ok, so here are some screen shots.... they will be thumbnails, the 1st will be the WORKING win7 computer, and the other will be the NOT working one.. (I'll label the screens themselves...)

So , there are all the settings.. and they are all the same... what am I missing here.. why is it working in one and not the other?

The problem dose not seam to be in the folder permissions but in the computer it self.. as I can not even browse it on the network. I can see the workgroup and browse to it.. I can then see BOTH systems. I can click on the working system and go into see all the shares and then click to go into a share and read data from it (this is the working win7 system), but on the other system when I click the computer I nvr even get to see the shares.. it asks for a password and will not acept anythign i put in...

Any ideas what is going on I am at the end of my rope!!!

Thanks in advance!

---EDIT: UPDATE---

Hi there.. I think I have found the problem but I can not correct it... I finally found a difference in the setting deep in the group permission area.... see screenshot

As you can see the "Network - Security: Lan Manager authentication level" is set as "undefined" on the working system.. and it is set to "Send LM & NTLM response". On the other system....

The problem is there is no option to disable it.. so it must have been done with a regedit maybe? Anyway.. I guess this is the problem... any ideas how I can get this value to be undefined?

It seems like you're facing network connectivity issues with your new Windows 7 system, particularly related to accessing shares from other devices like your Linux box running Ubuntu. Let's break down the issues and potential solutions based on the information you provided:

Network Connectivity Issue Analysis:​

1. Password Authentication Problem:
   • You mentioned that when trying to connect to the new Windows 7 system from other devices, they are prompted for a password, but none of the credentials work. This suggests an authentication issue between the systems.
   • You tried guest accounts and no passwords, but the problem persists.
   []Folder Permissions vs. Computer Settings:
   • You clarified that the issue doesn't seem to be with folder permissions, but rather with the computer itself. Even browsing the new Windows 7 system on the network is problematic.

     Solutions to Consider:​

   []Check Network Discovery and Sharing Settings:
   • Confirm that network discovery is enabled on the Windows 7 system. Navigate to "Control Panel" > "Network and Sharing Center" > "Change advanced sharing settings" to ensure network discovery is turned on.
   []Workgroup and Sharing Configuration:
   • Verify that both systems are part of the same workgroup. This setting must be the same for seamless communication within the network.
   []Password-Protected Sharing:
   • Check if password-protected sharing is enabled on the Windows 7 system. You may need to turn this off to allow seamless access from other devices without entering credentials each time.
   []LAN Manager Authentication Level:
   • Regarding the LAN Manager authentication level difference you found, where one system had it set to "undefined" and the other to "Send LM & NTLM response," you can modify this through the Registry Editor.

     Adjusting LAN Manager Authentication Level in Registry Editor:​

   []Press Win + R, type regedit, and hit Enter. []Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa. []Look for the key LmCompatibilityLevel on the right pane. []Modify the value data to 1 for "Send LM & NTLM responses" or 0 for "Send LM & NTLM - use NTLMv2 session security if negotiated." []If the key is missing, create a new REG_DWORD entry with the name LmCompatibilityLevel.

   Important Note:​

   • Be cautious when editing the Registry: Making incorrect changes can impact system stability. Always back up the registry before making any modifications.
   • After adjusting the LAN Manager authentication level, reboot your system to apply the changes.
   Try adjusting the LAN Manager authentication level as mentioned above and ensure your network and sharing settings align with the recommendations. If the issue persists, further troubleshooting may be necessary. Let me know if you need assistance with any specific steps or encounter any difficulties during the process.
