Windows 7 Networking

Using XP, you may want to map to a drive on a Windows 7 machine, here's a couple of things you should do:

1. Definitely make sure both machines are in the same Workgroup (Win+Break will take you to there to check)

2. 

Go to Start>Type gpedit.msc (it is located at C:\Windows\System32\gpedit.msc.) Press enter to open it.  Click yes if UAC prompts you.

Go to Local Computer Policy> Computer Configuration> Windows Settings> Security Settings> Local Policies> Security Options>

Scroll down to "Network security: LAN Manager authentication level"

Change it to: “Send LM & NTLM, use NTLMv2 session security is negotiated”

The new security policy may not apply itself until reboot so restart to be sure.

3. After you've restarted, map the network drive as normal. If it still doesn't accept the username and password you are using (make sure they are correct for the Win 7 machine you are trying to connect to) try just pushing 'cancel' sometimes it just works anyway??!?!
