However, if you try to access or browse the mapped drive, it will reconnect quickly.


To solve this problem, change the default timeout period on the shared network computer. To do this, use one of the following methods.
Registry Editor

Warning improper use of the registry editor can cause serious problems and the operating system may need to be re-installed. Microsoft cannot guarantee that you can solve problems caused by improper use of the registry editor. You are at your own risk to use the registry editor.
