I have a user that is able to connect to our network thru a VPN with out any problem, but as he is logged in I see the following denied messages in the traffic on our Watchguard x1250e firewall.
2009-03-31 04:59:15 Deny 192.168.6.91 255.255.255.255 netbios-dgm/udp 138 138 PPTP Firebox denied 265 128 (Unhandled External Packet-00) src_user="rarmstrong@Firebox-DB" rc="101" Traffic
The user is not able to connect to our Exchange server to open Outlook, although he was doing this before we had some Firewall problems. He is using Vista, Office 2007 and is able to see the Network, including our Exchange server. He can see shared folders, but Outlook cannot connect. The client error message is "Exchange server is unavalable".
