Symptoms

You have a computer that is running Windows 7 or Windows Server 2008 R2. On this computer, you try to open a Microsoft Office 2003 document from a network share. However, the computer may take four minutes to open the document.

This issue occurs only in the first attempt to open an Office 2003 document from the network share during one day. Successive attempts to open Office 2003 documents from that share work fine. Additionally, this issue occurs when the following conditions are true:
  • The Office 2003 document is hosted in a network share on a domain controller.
  • You keep the computer connected to the network share for a long time before you open the Office 2003 document.

Note To reproduce this issue, see the "More information" section.
