SYMPTOMS
Each time that SharePoint Portal Server starts, the following error message may be logged in the Application event log:

Source: ExWin32

Category: None

Event ID: 1

Type: Error

Description:

The Exchange IFS failed to map drive ?:. Please free drive ?: to use Exchange IFS.



CAUSE
This issue occurs because SharePoint Portal Server does not map an Installable File System (IFS) drive to the Web Storage System; this is by design.



WORKAROUND
Gaining access to the workspace by using IFS can cause data loss and is not recommended. However, in certain situations (such as Web Storage System program development) you might want to work around this issue by mapping a drive to IFS to gain access to the workspace from Microsoft Windows Explorer. For additional information and instructions that you can use to enable drive mapping, read the &quot;IFS Drive and the Microsoft Web Storage System&quot; section in the Readme.htm file on your SharePoint Portal Server CD.



MORE INFORMATION
You can safely ignore this error message.
