SYMPTOMS

When you use network shortcuts to try to browse the contents of a folder on a remote computer, you experience significant delays on a computer that is running Microsoft Windows XP Service Pack 2 (SP2).

This problem occurs when the following conditions are true:
  • You click a shortcut in the folders pane in Windows Explorer that contains a Universal Naming Convention (UNC) name.
  • The UNC name references the folder that you want to browse.
  • You are connected to the remote computer over a slow network link.
Additionally, you may experience a delay in program responses when you use the Open, Save, or Save As commands to access a file that is stored on another computer on the network. This performance problem occurs if a UNC name references the file. This delay may be from 10 seconds through one minute. In some cases, Windows Explorer stops responding.

CAUSE

This problem occurs because the SHELL32! CShellLink::_ResolveLinkInfo() function is not optimized in Shell32.dll.

WORKAROUND

To work around this problem, map a network drive on the local computer to the remote computer. Browse the network drive on the remote computer instead of using a UNC network shortcut on the local computer. To map a network drive, follow these steps:
  1. Click Start, and then click My Computer.
  2. On the Tools menu, click Map Network Drive.
  3. In the Map Network Drive dialog box, select a drive letter in the Drive list.
  4. Click Browse, and then select a network share that will appear in the Folder box.
  5. Click Reconnect at logon.
  6. Click Finish.
