Ok I have a Juniper Network Firewall 25 and I have set up a vpn to allow traveling users to connect to our network and so they can use their outlook on the road (we had a new mandate that made me remove OWA)
The vpn works great, everyone can connect, if they have offline files they synch and they can ping the internl servers by both UDN name and ip address. Here is the problem, I'm getting reports back from the field that their outlook sometime won't ever connect to exchange box. If they are in a hotel that they can connect using outlook, they always can. If they are in a hotel were the first try they can't they never can. We also have a few users that have Verizon wireless broadband card so they can connect where ever. I'll use this one as an example since I can try it out in the office.
Using the boadband card I connect and then connect to the vpn. I can ping, synch and remote desktop to our internal servers including the exchange server.
When I open exchange, it just sits at "trying to connect". If I run from the command line: outlook.exe /rpcdiag it shows it first trying to connect to a DC server and then the exchange server. Nothing is dispalyed in the Interface or conn columns. This makes me believe exchange doesn't know about the broadband interface.
I could really use some help on this one ASAP. I need to get this connection more reliable.
