You have drives that show up in Windows Explorer, but they do not show up in Report Runner Viewer. You may also have drives that show up for one user, but not for another.
We make available the drives that Windows reports back to us that are available:
01/01/2013 11:39:53 - Drive list ----------------- A, C, D, H, J, M, R, T, Z
01/01/2013 12:58:45 - Drive list ----------------- A, C, D, E, H, P, T
Other drives may be visible in Windows Explorer, but due to security settings (UAC), Windows does not make them available to other applications.
Most of the time, this can be fixed with a registry setting. See this article from Microsoft:http://technet.microsoft.com/en-us/library/ee844140%28v=ws.10%29.aspx
Also note, as of 2013.130, we have a JNRRV.INI
setting that can be used to purposely hide drives from users. Please contact us for more information if needed.
