When you use antivirus software to scan the files that make up Microsoft SharePoint Portal Server 2001 or Microsoft Office SharePoint Portal Server 2003 and the Microsoft Exchange Server information store that SharePoint Portal Server uses to store files for the portal, you may receive error messages similar to (but not limited to) the following:
Check-Out Error

The document could not be checked out, because of the error (0x80040e92):
No description was found for this error.
Check-In Error

The document you are attempting to check in is currently in use.
This behavior can occur because antivirus software frequently locks files while scanning files and folders, and this may produce a wide range of unpredictable results for SharePoint Portal Server.
To resolve this behavior, configure your antivirus software so that it does not scan the following files and folders:
  • Drive:\Program Files\SharePoint Portal Server
  • Drive:\Program Files\Common Files\Microsoft Shared\Web Storage System
Where Drive: is the drive letter where you installed SharePoint Portal Server.

Note Typically, this is drive C.

Additionally, you must consider:
  • If drive M is mounted, you must exclude this drive from the scan. For additional information and for details about this configuration, click the following article number to view the article in the Microsoft Knowledge Base:

  • If any data was placed in another location throughout the installation process you must exclude that location also.
  • If you are using Microsoft SharePoint Portal Server 2003 and you apply Service Pack 1 (SP1), you must exclude the following folder from Anti Virus scans:
    After you apply SP1, SharePoint Portal Server 2003 uses this folder when it uploads large files.
To configure these options, see the documentation for your antivirus software, or contact the antivirus software manufacturer. For information about how to contact P1, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base:
