After you install MS11-021 and the Office File Validation (OFV) Add-in for Office 2003 (KB 2501584), workbooks stored in a network location open slower over the network in Excel 2003 than they did without the OFV installed. The decrease in performance depends on the size of the workbook and bandwidth of the network and in some scenarios can seem to hang Excel.
To be able to have both the protection of the OFV, and typical performance over the network when opening files, upgrade to either Microsoft Excel 2007 or Microsoft Excel 2010.
Copy the file to the local workstation. Open and save it in Excel from the local hard drive. Copy the file back to the network location.
Note: If multiple users are accessing the same file, you must be cautious to collaborate with the other users before you copy the file back to the share so that you do not overwrite the changes that were made by another user. The Shared Workbook feature cannot be used with this workaround.
To use Excel 2003 and avoid the network performance issue, you can disable theMicrosoft Office File Validation Add-In for Excel by using a registry setting. This removes the additional protection of the OFV for Excel while still protecting the other Office applications.
