<div>
I've increased the priority values for 1 on the SRV records for the older servers. &nbsp;<br />
<br />
To test this I've logged on and off 10 times and only once did I get an older server processing the request.<br />
<br />
Does anyone have experience of doing this a better way? &nbsp; &nbsp;(We only have 1 AD site and subnet)

<div class="content wysiwyg-content">
I have 5 domain controllers:<br />
<br />
3 x Windows Server 2008<br />
2 x Windows Server 2003<br />
The FSMO roles are split between the 2008 servers.<br />
<br />
How can I safely ensure the three 2008 servers take priority over the 2003 servers for processing logons? &nbsp;<br />
<br />
I could just demote and decommission the 2003 servers but we rely on them for DNS as various systems still point to them.<br />
<br />
A google search showed that someone disabled the netlogon service to achieve this and others disabled the Active Directory services. &nbsp;But I still need them to function as DNS servers and our zones are AD-integrated.
