Thank you for your interest in Syncfusion Products.
Please complete the following steps to upload files to a Windows 2008 server.
1. Add the upload module also inside the System.webServer in the Web.Config
2. Give "Full Control" to the upload path you have specified.

Please try this and let me know if this helps.
