Microsoft has just released a Knowledge Base article about the fact that Windows Vista systems using Folder Redirection are experiencing slowness’s of about 30 seconds when you do not have a connection to the network, i.e. are at home, traveling etc. The support article state that the system may be unresponsive when opening Windows Explorer and other applications. This problem has been haunting many users, including myself and it is nice to see a solution, although it should have been published a long time ago. Waiting for Service Pack 1 I strongly recommend this to anyone using Folder redirection and having laptop computers running Windows Vista.
A Windows Vista-based computer is frequently unresponsive for 30 seconds if the Documents folder is redirected to a shared folder, and the folder is made available offline
