infoRouter uses warehouse paths to store document content and other meta files.
If you get this message it means that infoRouter was unable to access the specified paths at application start up or during the course of normal use.
Make sure that the path specified in the error message exists and is accessible by the ASPNET, the Network Service account or the impersonated user account depending on your OS.
If your warehouse paths reside on another machine. Use UNC Paths instead of mapped drives. Mapped drives are profile based.
UNC paths must be accessed using a domain account and this domain account must be indicated in the WEB.CONFIG file.
<system.web> ... <identity impersonate="true" userName="domainname\username" password="pass"/> ... </system.web>
You must also make sure that the impersonated account has Full Control to the UNC paths. Do not allow "Everyone" access to these paths.
