More For Windows 7 Sharing

I believe this is the GUI procedure for the previous post...

Please follow change the NTLM authentication level.
Network security: LAN Manager authentication level
To change the policy, open gpedit.msc from Start Search box, locate to:
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network security: LAN Manager authentication level
Change the value to “Send LM & NTLM - use NTLMv2 session security if negotiated”.
If your system is Windows 7 Home Premium, you may change it from Registry.
1. Launch regedit from Start Search box.
2. Find the following branch.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Create a DWORD key under Lsa and set:
Name: LmCompatibilityLevel
Value: 1

4. Restart.
