Windows Server 2003 Virtual Machine SMTP Problem

I'm running an Exchange 2007 SP1 server.  While installing a helpdesk app it asked for IMAP or POP to send emails out.  I wasn't using either on my Exchange server, so I  set them both up.  I can receive email externally and internally from my workstation and physical servers with both POP3 and IMAP and send via SMTP, but not on the Windows 2003 virtual server I setup in VMWare (1.0.4).  I ran TELNET MyVirtualServerName 25, connected, did a HELO and it hangs eventually saying "Conneciton to host lost.".  I tried it on another virtual machines (located on the same physical VMWare box) and it worked, but not on all virtual machines.  All virtual machines are R2 SP2... Any ideas?

Check your virus protection and windows firewall.  One is likely blocking SMTP port 25

No virus or firewall on...good idea checking, though.
Another thing to check is that you have authorized that particular server for anonymous mail relay.  This article may hold a nugget of usefulness as well http://msexchangeteam.com/archive/2006/12/28/432013.aspx
have you tried unbinding the SMTP virtual server in Exchange, and allow it to use 'all' ip's.

SP2 on Exchange added an IP offload setting on my servers Broadcom card...it caused the connection to be frequently dropped...turning that optoin off fixed my problem.
