Exchange Server 2003:<br />
<br />
I have a dedicated server at a data center that I terminal services into. &nbsp;I recently installed Exchange Server 2003 Standard from my licensing. &nbsp;When the hosting company setup the server the name of the server was &quot;sls-ce10p12&quot; and they had a DNS Suffix of sls-ce10p12.dca2.superb.ne<wbr />t <br />
<br />
Well, in doing other things I found this out but AFTER the fact that I promoted this server to a DC to run my Exchange.<br />
<br />
I removed the DNS Suffix but the outside is still seeing me at sls-ce10p12.dca2.superb.ne<wbr />t and appliances like Barracuda are rejecting me like so. &nbsp;How can I fix this?<br />
<br />
There was a SMTP communication problem with the recipient's email server. &nbsp;Please contact your system administrator.<br />
