I am having SBS 2003 on my system. There are around 7 Windows XP clients connected to the server. Now I am trying to add a new laptop to the server. For that I had downloaded a new Windows Update. It is installed on the server. After updating there was a problem with connectivity. A error appeared while configuring the network settings. There is a Windows 7 system which is also not connected to the server. Even after adding all the manually settings it fails to work.
