infoRouter needs to create temporary files during uploads, downloads and searching.
This problem occurs when infoRouter checks the temporary drive check fails at application start up.
infoRouter attempts to read, write and delete from this location and if any of its attempts fail, this message is issued.
infoRouter uses two different temp folders
One is defined in the application settings. By default it is C:\TEMP.
This folder used for large temporary files such as zipping folders and documents and paging through large search results.
The location of the secondary temp folder changes based on your OS.
On IIS 5 and IIS 5.1, the ASPNET account temp folder is profile based and is usually stored under "c:\documents and settings" folders.
On IIS 6 (Windows 2003) the Network Service account temporary folder is located under the WINDOWS\tmp folder. This temporary folder used for uploads.
Make sure the path specified in the error exists and the ASPNET or the NETWORK SERVICE account has Full Control permissions to this path.
On Windows 2003 make sure that the NETWORK SERVICE has Full Control to the C:\Windows\tmp directory.
