I currently have Windows 2003 Server on our domain controller and SQL server 2008. &nbsp;All our clients are Windows 7. &nbsp;We are upgrading our SQL box. &nbsp;The question I have is if we upgrade the SQL box to Windows 2008 or 2012, will that become an issue if we leave the domain controller as a 2003 Server. &nbsp; Does it allow a hybrid enironment? &nbsp;<br />
<br />
Is there any benefit also to upgrading to SQL 2012?<br />
<br />
To me, it seems like these upgrades are unnecessary and maybe we should just stick to our old 2003 Server with SQL 2008.<br />
<br />
Your thoughts on the matter are appreciated!
