Not looking for output, just using this as a test to check why drive isn't
mapping. I'll try the code you sent and see if that works. My application
needs to give the client the ability to map to a Netware server, and rename a
file in that mapping that another esternal application process checks. That
process then does something depending on the existence or not of the
named/renamed file.
As I have over 250 netware servers I need a web application tha does
monitoring as well as other routine tasks such as this.

Hi Brian,

This J# ASP.NET web app is working for me.

Please try to trace the returned value from the :
int ret = (int)this.WNetAddConnection2A( str, "password", "myUsername",
dwFlags );

And look it up in this error code list:
http://msdn.microsoft.com/library/en-us/debug/base/system_error_codes.asp

What error (code) do you get?

Sorry, I don't know of any J# books describing anything like this. This MSDN
page is probably the closest to any docs on the drive map api we get.
