Does MS Exchange 2010 works with firewall on?
This is a newly setup MS Exchange 2010 server, installed on MS Windows 2008 r2 server. The Windows firewall is on. Now, I can telnet to port 25 on local exchange server. But, on other desktop, I can't telnet the port 25 of the exchange server. Does exch 2010 managed to work with firewall on?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You should of course find that Windows firewall was configured by the exchange setup in the manner described on this page....

If you had windows firewall turned on when you istalled exchange 2010, the setup will punch the holes that it requires. So, yes. Exchange 2010 will and should work with firewall turned on.
Do you have telnet installed on the client from which you are telnetting??

P.S.
You would never really want to access port 25 on the server from the desktop would you? Except for this test.
