I have a network corporate side is connected to four branch offices with full T1 and branches are also connected to each other through Frame-Relay in a full mesh topology as a backup.
Everything is working fine, all the branches have installed the preferred route through T1 link to reach the corporate network and other sites. Just to confuse you I have a DHCP server running at the corporate as well as one of the branch sides. All the branches have a IP helper address pointing to a DHCP server which is running on a branch office. In other words, traffic goes to the corporate first then from there go the branch office for dhcp lease ip address and logon to a windows 2000 domain. It is just a temporary solution. Eventually all branches will be pointing to the corporate office through wins or ip helper address for logon to a windows 2000 server. Here is the issue, one of the branches even though is going through a preferred route through T1, all the windows hosts will not even boot up and stuck in a black screen mode if Frame-Relay link is up which is S0. When I say up it means that is ready to take over incase of the primary link which is Point to Point fails. As soon as I shut down the S0 interface for Frame-Relay link, and then boot the hosts they boot fine and also logs on to the windows 2000 domain. I even made sure that the branch is installing the preferred route through T1 link and will only go through FR cloud if primary link goes down. I can't figure it out how Frame Relay interface can possibly conflict with this problem. Other branches are working fine with being Frame-Relay interfaces are up. Does anyone have a clue? All the help will be appreciated.
