I have a few 2820's on fw 3.3.3_232201, the problem is that the regional office link appears to be in place looking at the timer on both routers, but outlook will not connect to the exchange server at the head office.
if i reboot the regional router then it connects fine but the outlook client will lose connectivity a few hours later and another reboot will be needed. Has anyone had a similar problem?

cheers
Paul

is there a hosts file on the client PC?

e.g. your Outlook / MS Exchange Server is mailserver.company.local with an IP of 10.10.1.10

in the hosts file there's an entry mailserver 10.10.1.10

Does the domain authentication work ok when the client logs on ?

Is there a Different IP range in use at each site.

Have you fried the later firmware 3.3.5.2 and does this help ?

Regards,

Neal
