Cannot get Exchange email with Outlook 2007 through wireless connection

[john doe]

We have Win2003 w/exchange and we have a laptop with WinVista with Outlook
2007 and it won't connect to exchange through the wireless connection. But
it can get on the internet.
Then I turn off the wireless and connect the network cable to it and it
works fine with exchange, etc...
Does anyone know why I can't connect with the wireless to exchange?
Please advise and thanks.

Is it an internal to your company connection or an external connection?

Internal and thanks for your help.

Hmmm, check with your IT folk if they've got some sort of differences
between the wireless & wired network. I know in our offices there's a
firewall of sorts between the wireless net and the rest of our
infrastructure.

Do you have a firewall, or different firewall settings, running on your
wireless than on your wired connection on that laptop?

Can you ping the Exchange server, by name, from that laptop?

What version of exchange? Are you using outlook anywhere (rpc over http) or
classic rpc? Did you check the connection status? (ctrl click the outlook
icon in the tray)

No, nothing is different. I've turned the firewall off on the vista laptop
which turns it off for the wired and wireless.
I can't ping the exchange server by name but I can ip address with the
wireless connection.
I can ping the exchange server by name and ip with the wired connection.

Our exchange version is:
ver 6.5 build 7638.2 sp2

We are not using rpc over http. We are using the local lan.
Here's the connection status error I get while using wireless:
Task 'Microsoft Exchange' reported error (0x80040115): 'The
connection to Microsoft Exchange is unavailable. Outlook must
be online or connected to complete this action.'

Everything is fine with the wired. Even with the wireless I can
still surf the web, etc... except for getting my email via exchange
into Outlook 2007.

Sounds like you have a DNS issue on the wireless LAN adapter. Check the
TCP/IP settings on the wireless adapter and make sure you've got the right
DNS servers assigned.

Yes, you are right. The DNS was wrong on the wireless. Thank you for your
help.
Much appreciated and solved.
Thanks
