infoRouter uses warehouse paths to store document contents and other meta files.The warehouse paths are specified at install infoRouter was unable to access the specified paths at application start up.
Make sure that the path specified in the error message exists and is accessible by the ASPNET, Network Service account or 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.
