Exchange 2007 on 2008 Server

I just installed Exchange Server 2007 onto Windows 2008 Server, all seems good, except I cant telnet into it from another PC on the same Network. I can send email from it, and I can send email from it to itself, but I cant Telnet into it on Port 25.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try running the following to confirm that port 25 is listening:  netstat -a | find "LISTENING"

Assuming it is have you got a firewall enabled?  If so have you added the necessary exceptions?

Are there any policies in your setup that restrict Telnet, check that PC does not have any AV that might be blocking port 25 or else Firewall rules
Did you install the 'Telent Server' under features? Also make sure you have the ports open as lamaslany stated - the firewall in Server 2008 is much more robust then the one in Server 2003.
I hope this helps. Good luck.
You shouldn't need the Telnet Server feature installed as you are connecting to the SMTP service rather than a telnet server.

Ran the command and found my Trend Micro had blocked port 25, opened up that port, now all is good.
