XWEB: Computer Running Internet Information Service Prompts to Insert Disk in Drive A (247061)
The information in this article applies to:
- Microsoft Exchange Server 5.5
This article was previously published under Q247061 SYMPTOMS
If you use Microsoft Internet Information Service (IIS), a dialog box may be displayed on the computer running IIS that prompts you to insert a disk in drive A. The computer running IIS stops responding until you click Ignore.
CAUSE
Microsoft Outlook Web Access (OWA) only parses the directory name from a full path string by using a backward slash (\). If a user attaches a file that is wrong,
for example, A:/Test.txt, OWA still uses "A:/Test.txt" as the file name (without the path). The global ErrorMode variable is generally set to "SEM_FAILCRITICALERRORS" in the Inetinfo.exe file, so any further processing of the file stops immediately and an error message is generated. However, if the ErrorMode variable is changed,
some processes, such as CreateFile, do not stop responding, but they generate a prompt to insert a disk in drive A. Some dynamic-link libraries
(DLLs), such as the Mapi32.dll file, actually temporarily change the ErrorMode variable. This problem can occur in a high-stress environment.

Component: Outlook Web Access
STATUSMicrosoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. MORE INFORMATION
The code in the Attach.inc file is changed so that it parses the path by using either a backward slash (\), a colon (:), or a forward slash (/), so that such invalid characters are not parsed into file names.
