Excel 2003 Workbooks Open Slowly Over Network

Been trying to open an Excel file over a network and noticed that it would take several minutes to open.

Adding this registry tweak solved the problem by disabling the Office File Validation (OFV) add-in.

Go to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\

Add this key entry: Excel > Security > FileValidation > EnableOnLoad

Set the key value for EnableOnLoad as a 32-bit DWORD with the value of 0.
