VPN problems connecting to Exchange server

[Brendan Jones]

I cannot set up Entourage via my company's VPN. I get a message that
my Exchange server is unavailable. Full detail is at the bottom of
this message, but in summary my setup details:

Mac: OSX 10.3.8
Entourage: Office 2004
VPN Client: Netlock Contivity (Nortel)
Corporate network uses proxys for HTTP, HTTPS, etc
Mac OSX Firewall: On. Ports 135 (Exchange) and 500 (Netlock) are open.
IP address assigned by DSL modem and appearing in "Network" system
preference panel: 220.236.xx.xx
IP address Nortel Contivity Switch: 61.88.xx.xx
IP address assigned to my Mac by Nortel Contivity Switch: 10.64.xx.xx
IP address Exchange Server: 10.18.xx.xx

Entourage Errors:
Entourage error connecting to my Exchange server: -3260
Entourage error connecting to my Exchange server if I replace its name
with its IP address: 114
(If I put my Exchange server IP address in my "proxy bypass" list in
"Network" system preference panel: -3260)


The curious thing is some aspects of the setup work. An LDAP server is
found which works (I can look up people's names). It finds the
Exchange server my account is assigned to (SOCNTE008) but it cannot
connect to the server itself.

Also if I enter a non-existent user ID I get an error that "the network
you connected to doesn't recognise your name, password or domain.
Check the settings and try again." So some server is being polled, and
recognising what is and is not a valid user ID.

I can use Apple Mail (IMAP) to read mail on
socnte008.companyname.com.au, but clearly this does not offer me the
full Entourage capabilities.

Any clues as to what is going on with Entourage? Thanks!

Hi,

Entourage Errors:
Entourage error connecting to my Exchange server: -3260

That's a network problem. I suspect the IP doesn't properly reverses to
the domain name or the opposite.

Entourage error connecting to my Exchange server if I replace its name
with its IP address: 114
(If I put my Exchange server IP address in my "proxy bypass" list in
"Network" system preference panel: -3260)

The KB says for this one:
Exchange 2004- This error indicates a proxy error from netlib. Check
Proxy support setup. Try requires authentication.

Any proxy you might be using ??
