I have a point-to-point setup between two locations with point B users (connected to a switch connected to a Cisco 2500 router (ip 192.168.10.1)) accessing the network services at point A. When I setup the routers on each end I tried to do as little programming as I needed. For the most part, point B is successfully able to access the point A network. I am experiencing two annoying issues as follows:
(1) Outlook Exchange. When a point B user opens Outlook, Outlook takes longer for the point B user to open then it does for the point A user. After some investigation, I have discovered that Outlook software uses a mail server name as opposed to a mail server ip address; and, the point B user Outlook takes awhile to resolve this mail server name (eg. am1st-mail1). In the client Outlook setup, I have tried replacing the name with the ip address and each time I do this the ip address resolves much quicker but after resolving Outlook setup changes the ip address into the name. Since I cannot force Outlook to always use the mail server ip address (eg. 188.8.131.52) in place of the mail server name (am1st-mail1), it takes about a minute to open Outlook.
(2) AOL. When a point B user loads AOL, the AOL software cannot (find) connect to the Internet. When a point A user loads AOL it automatically finds the Internet. I have tried to manually set the point B user AOL software but that does not work. My assumption is, the time it takes for AOL to find the Internet is longer then what the AOL software allows and according to AOL there is no way to increase the timeout.
Is there something I can do in my router configuration to eliminate these issues?
