I have a user that has a number of computers in is home connected to the main office LAN via a dedicated T1. He has a number of computers that access outlook with no problem. On one computer though, when he attemtps to either send a link or send a page, when looking at a web site in Explorer, after a long delay, he gets the pop up window: Your Microsoft Exchange Server is unavailable. However, this computer has no problem accessing the exchange email. Also, other comuters in the home don't have any problem doing a send page or send link, only this one computer. I have verified that the default email program indicated in explorer is MS Outlook.
