I recently put two new Windows 7 Professional machines into a dated network environment. The server is running Windows 2000 Professional (Workstation, not server) and I can't get the Windows 7 machine to connect to it. There is no domain for this network.
On the server (We'll call it data1, the Network share is shared with everyone (i.e., everyone who has a local account on the machine). When I go to connect to it on one of the Windows 7 machines, I get a prompt for a network password. I have tried all accounts on the server using the domain prefix like data1\user. But it doesn't connect – a "invalid username or password" error comes every time.
For a stopgap solution while I get this worked out, I built a new server of off Windows Server 2003. All machines can connect to it (Windows 2000, Windows XP and Windows 7).
Is it just that Windows 2000 is too old to connect to Windows 7? Thanks for your help.

LmCompatibilityLevel as already suggested plus look at secpol.msc -> local policies -> security options -> lan manager auth level. as far as I remember Win7 uses NTLM2 by default, try setting it to "LM & NTLM, NTLM2 if available" or so.
