We've setup a SBS 2003 Premium network with Windows XP Pro clients. All machines were added to the network using connectcomputer. All are desktops except one user who is using a laptop due to traveling and home usage. We have NOT setup wireless access points in the company. However, the laptop previously connected to an open wireless network of a company next door. Because of this, obviously, he was going offline via the LAN network connection.
I tried removing the wireless card (external) when he is in the office and ensuring he connects via the LAN cable. (I think he had a cached connection to the wireless that I couldn't get rid of)
Because the laptop was old and slow, we purchased a new laptop. I'd like to avoid the issue on the new laptop but still give him the flexibility to control his wireless connection for when he travels or works from home.
