i have an issue with an SBS server. The SMTP service is running in services. yet when i try to run default smtp virtual server in exchange system manager i get the following error

Event Type:      Error
Event Source:      SMTPSVC
Event Category:      None
Event ID:      115
Date:            16/03/2009
Time:            13:35:04
User:            N/A
Computer:      APSERVER01
The service could not bind instance 1.  The data is the error code.

0000: 40 27 00 00               @'..    

I have changed the port for the default SMTP and it starts fine. Yet when you change it back to 25 it no longer works.

If I telnet to it I get the following error

Invalid user.

Connection to host lost.

C:\Documents and Settings\rich>

It looks like something else has taken control of port 25, but i cant find what it is.

Thanks in advance.
