How to Call "Enter Network Password" dialogbox i n Win2000?

[host28]

I am programming item with windows authentication . Our client may be working in winxp or win2000. 　Client must input username and password .So I use CredUIPromptForCredentials() in winxp. But this function is not supported in win2000. I have not found replaced function. I find that "Enter Network Password" dialogbox in win2000 is fit to me .But I don't know how to call this dialogbox and how to get user name,password? Could you give me some advice? Thanks

The WNetConnectionDialogfunction starts a general browsing dialog box for connecting to network resources. The function requires a handle to the owner window for the dialog box.
