Hi

Have a site to site VP N problem
The network servers are Microsoft windows server both 200 and 2003.

AT one remote site using an ASA to ASA VPN clients could pick up email
from an exchange server buy not send email.

The site with the exchange server cold VNC to the machine that could
not send email

When one browsed the network one could see only local machines. The
domain controller at the remote site had lots of id event 1311 in the
directory log.

Machines could not connect to an SQL server using active directory
credentials but could get to a web site on the same machine.

Change the remote site to A PIX 501 solved the problem


Mugged config of remote site


Thanks in advance for any help
