Hi,
On of my client site is having an exchange environment, it has two exchange servers (Exchange 2010 with SP3), each server has MBX/CAS/HUB server roles installed. A DAG has configured as well.
Issue is when we access the OWA externally (from internet) the page loads with a delay and once we enter the user name and password it loads the interface but the browser tab is showing the busy status for a long time (circle icon is working for about 1.5 mintues to 2 minutes) once it is completed only the user can work with OWA.
There is no error related to this in the exchange server as well and no problem when accessing internally.
When we do a Ping from internet lot of timeouts are happening and found when we stop the Hub transport server service the ping continues and owa works as usual
They have a 512 kbps leased line allocated.
Thanks,
Kanishka.
