1. My network protected by firewall. I can telnet those ports from the
network, but can't from outside.
2. NAV 7.6 and NAV 2.52 for Microsoft Exchange installed on server running
Exchange.
3. I am not using IISLockdown and URLScan
4. I am already scan this machine from McAfee site and not found nothing.
Any suggestions?
