Cow Computing

Unlike Windows XP, mapping a network drive in Windows 7 is a nightmare. It is possible that during the mapping of a network drive, no matter how hard you try to enter your credentials or the drive is actually password-less, it still prompt you for a password repeatedly. This is annoying and is due to the security settings on Network Security. I shall introduce you two method to get around this annoying problem. *Do note that, for Windows 7 Home edition, the security setting is not available (RIDICULOUS isn’t it?), either you upgrade to Professional / Ultimate Edition or you could use Method 2 to achieve that (HURRAY!)

Method 1 (Windows 7 Professional / Ultimate Edition)

1. Under “Control Panel”, find “System and Security”
2. Open “Administrative Tools”
3. Double Click “Local Security Policy”
4. Expand “Local Policies”
5. Click “Security Options” and Scroll to find “Network Security: LAN Manager Authentication Level”
6. Choose “Send LM & NTLM, use NTLMv2 session security is negotiated” for the drop down.
7. Done. you can now map network drive as normal (like in XP)

Method 2 (Windows 7 Home Edition)

1. Use notepad and save the snippet below as win7fix.reg

   Windows Registry Editor Version 5.00
   
   [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
   "lmcompatibilitylevel"=dword:00000002

2. Double click the win7fix.reg you just create to run it
3. Press “Yes” to add that into registry
4. Done. you can now map network drive as normal (like in XP)
