<a href="https://stackoverflow.com/questions/3098486/cannot-access-files-on-drive-mapped-network-share-from-a-windows-service">This SO post</a> describes a similar scenario to what you've described. One of the links posted as a response to that question led me to <a href="http://msdn.microsoft.com/en-us/library/ms685143.aspx" rel="nofollow noreferrer">this MSDN article</a> which provides a variety of reasons as to why one might encounter errors when trying to access shared network drives by using a mapped drive letter. Microsoft's suggestion (see below) is to simply use a UNC path. <blockquote> A service (or any process running in a different security context) that must access a remote resource should use the Universal Naming Convention (UNC) name to access the resource. </blockquote> To answer your actual question more specifically, with regards to why it suddenly can't access the network share, I would venture a guess to say that the network share is being disconnected by Windows due to an idle timeout, as discussed in <a href="http://support.microsoft.com/kb/297684" rel="nofollow noreferrer">KB297684</a>. Any attempt to access the disconnected drive will be met with a small wait as the connection to the network share is re-established, which could presumably be what is causing your issue. To test this theory, try writing some data to a file on the network drive at a relatively short interval (every 10 minutes, perhaps?) to try and convince Windows that the drive is still active.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
