I work for a charity organisation in Glasgow and I have received excellent advice from various members over the last few months. We have signed a deal with a telecommunications company for them to roll out a voice over IP solution throughout our company (80 users). Following on from the company working late last week, the following morning our staff began experiencing difficulty with email access. In order to rectify this problem we had to carry out some re-routing. The set up of the email before installation was that email would route through the MAIL server and then the ISASERVER which was used as the gateway. This was changed by the telecommunications upon installing the new equipment. At present our company consists of a main site and 3 remote sites. At present, we cannot connect to the main DNS server from these sites and as such we cannot access files etc from these sites. However, at these sites the VOIP phones do work. There is a switch and a router set up at each remote site and there is a hub at the main site. Please can anyone offer any reason why the remote sites can’t now reach the main DNS server at our central site.
Thanks,
Marc
