SYMPTOMS

On a Windows Vista-based or Windows Server 2008-based computer, you try to access a network share by typing the path of the share in the Run box. However, it may take more than 10 seconds for the network share to open in Windows Explorer.

For example, in the Run box, you type the universal naming convention (UNC) path of the share, such as \\ServerName\ShareName. When you do this, it takes the Windows Explorer more than 10 seconds to open the share.

This issue occurs if the firewall of the server on which the share resides blocks traffic on port 80.

CAUSE

This issue occurs because Shell32.dll applies the file name extension detection logic to the path that you type.

After you enter the share name in the Run box, an additional period (.) is appended to the server name. This behavior results in requests for the path \\ServerName\.*. Because this path is an invalid network path for the server message block (SMB), the WebClient service tries to connect to the server through TCP port 80. If the firewall is enabled on the server, and the TCP port 80 is blocked, no response is sent by the server. Therefore, the client waits for the time out to expire. This results in a delay of 10 to 20 seconds.
