Accessing Mac OS X Windows Sharing from Windows 7
Windows 7 will not work with Mac OS X Windows file sharing support by default. If you attempt to access a folder shared from Mac OS X, Vista will display a logon error repeatedly.
The problem is that Vista, by default, will only use NTLMv2 for authentication, which is not supported by Mac OS X's Windows Sharing service.
Scenario : This will work if the two different computers are on same network.
The other problem is the Minimum Session Security for NTVLM SSP based Clients.
To get around this:
1. In Vista, open the Control Panel
2. Switch to "Classic" view
3. Double-click Administration Tools
4. Double-click Local Security Policy
5. Or Secpol.msc
6. Expand "Local Policies" and select "Security Options"
7. Alternate : Type secpol.msc to get editor up then
8. Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it.
9. Change the setting from "Send NTMLv2 response only" to "Send LM & NTLM - use NTLMv2 session if negotiated"
10. Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients
11. Change the setting from "require 128 bit" to unchecked (No Minimum)
12. Click OK
The Only difference between vista and windows 7 procedure is 10 and 11
