I recently performed some maintenance on an Exchange server (moved the log directory to a more ample hard drive) (and replaced our network switch with one with a Gbit port for our server).
Now we can't access our webmail through http://mail.nationaleventsllc.com/exchange
though this used to work before. We have DirecPC satellite internet hookup.
when I went to http://whatismyip.com
from a machine on the lan it gave me a diff IP than the one given by mail.nat..... but I don't think that the IP addy changed because that would just be too much coincidence that it happened at the same time as my changes.
The webmail IS available inside the LAN.
I am able to telnet in port 25 to mail.... and also open a connection on port 80 to mail.... but I can't get a browser to pull anything up from that addy
