ASP.NET and IIS - Network Directoy access from Business Logic Layer

[a2bjumper]

We are in the process of creating a website for a business on the ASP.NET 4.0 framework and IIS 6.0 - must hold the best pattern and practices.Issue:We need to access network directories in our business logic layer.Clarification:We have a business logic layer built into a separate project. How would we need to access the network directory content? Is that directly (\XYZ123\folder\folder\file.xml) or through IIS?If it is through the IIS, how to access the virtual directory mapped network directory - The Server.MapPath() can't be used in the business logic project, because it belongs to the Page!Let me know for other better options as well, Thank you,
