Hi.<br />
<br />
We have a client who has an SBS 2011 Server and we are looking at some DNS issues.<br />
<br />
This server was a swing migration from SBS2003 and it looks like there are some entries in their reverse lookup zones referring to their old SBS2003 server.<br />
<br />
My question(s) is:<br />
<br />
Is it OK to remove all references from the Reverse DNS Zones to the old server (Without doubt this server no longer exists on their network)<br />
<br />
Is it OK to remove all references in DNS for the OLD SBS2003 server name<br />
<br />
Would these entries in DNS cause any issues at all?<br />
<br />
Thank you and Regards<br />
Andy

DNS Entries in SBS2011 Reverse Lookup Zones.

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
