256986 Description of the Microsoft Windows Registry



SYMPTOMS
In Windows Explorer, a shortcut to a file on a remote server is displayed as a default icon, rather than its registered file type.



CAUSE
This problem occurs if there are large numbers of shares on the remote server and the links between the two servers are slow, for example, with RAS connections. When you double-click any one of these default icons, it will not open. Windows Explorer acquires the icon asychronously, and will abandon this operation after a time-out value.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, create the following registry entry:

 Start Registry Editor (Regedt32.exe). Locate the following key in the registry:

NOTE: The above registry key is one path; it has been wrapped for readability. On the Edit menu, click Add Value, and then add the following registry value:

Value Name: NetLinkTimeout

Data Type: REG_DWORD

Value: 7500 (milliseconds)

 Quit Registry Editor.

You may set it to a larger value, such as 9,000 (9 seconds). If it still fails, increase this value by 1,000 each time.

The drop target icon is also changed to this time-out value; by default, it is 1 second.
