Back from Spain! I will summarize my trip a bit later =)
A few days ago, i found that my office computer was getting slower and slower and it always hanged for a while whenever i did any action on the Windows Explorer. So i migrated all the stuff to a new computer and try the Windows 7 Professional which HKU provided. Note that this is not the RC version. =P
My first feeling on Windows 7 is quite good. Much much faster than Vista and all XP softwares such as Tortoise SVN, VM Player, DB Visualizer … could run without any problems.
Except one thing…
I cannot map to the network drive! It said the password is not valid!
so i asked the Google teacher and finally found the solution. here comes what u need.
1. Open the Administrative Tools in the Control Panel in your Windows 7 (NOT the network drive server)
2. Open the Local Security Policy
3. Select the Security Option under Local Policies
4. Choose Send LM & NTLM responses in Network security: LAN
manager authentication level
All done =)
* Update on 2010-03-01: If your network drive host is a Windows 2000 server, you may need to upgrade it to SP4. Thanks for Parsant’s finding. =)

For windows 7 home premium i found this solution to work just fine.
I found the solution at : http://social.technet.microsoft.com/Forums/en-US/w7itprovirt/thread/e08c3500-a722-4b44-b644-64f94f63c8e5/
For win Home Users:
you can edit the registry yourself by doing this:
1) open Notepad:
2) copy this text and past in notepad:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] “lmcompatibilitylevel”=dword:00000002
3) save the file on your desktop (or anywhere else) as name.reg – “.reg” is important.
4) run the file and press yes on the 2 poppups.
Now it should be fixed.

* Update on 2012-06-12: Some suggestion on Win7 + Kaspersky. Thanks Sheir. =)
1) in Kaspersky, check that Remote Desktop is allowed in trusted network
Kaspersky->Settings->Firewall->Settings>Packet Rules tab -> Remote Desktop
allow for Trusted Networks
2) Verify the ip address of the machine
Cmd -> ipconfig
3) run Notepad in Administrator mode (right-click run as administrator)
Open the Host file (Windows\System32\drivers\etc\host)
add entry with your machine name and its IP address
4) then try to ping your machine with its name

Correcting the time and date on the client and server may also help solving the password is not valid problem.
