I have a strange DNS issue. when a compute is using dhcp on my domain everthing works perfectly, there are no problems resolving internal DNS names, but if I give a computer a static IP and assign the dns servers manually in the TCP/IP settings they will no longer resolve our internal dns names??

Hoping for some ideas, this is not breaking anything but I don't understand what is happening

have you checked the DNS settings when DHCP assigns it to make sure it matches your manual settings? also, do you use WINS on your network? if so, is it being assigned by DHCP but not when you do it manually?

the DNS settings I am assigning manually are correct and the do match the automatic settings, and we are not using wins. we have 2 domain controllers that are also the DNS servers and DHCP servers

When you assign the static IP are you also assigning the Preferred DNS Server to be your Domain Controller - if not this could be the issue.

do your DNS accept dynamic updates?
Is the option "register this connection" enabled in the TCP/IP settings? run a "ipconfig /reisgerdns" to force a registration.

This is a pretty common issue.  What is happening is they are not appending the domain name portion of the connection when they are looking up internal computers.

The computers with static ip addresses need to have this set in TCP/IP properties.

In TCP/IP properties of the connection, advanced, dns tab, enter in the domain name under append these dns suffixes in order.  For example enter the full AD domain name.

This seems to be occuring because when they are setup for DHCP they are getting a connection specific dns suffix as a part of their DHCP lease.  When they no longer receive this and are static they don't get this and this problem occurs.  Try adding the domain name into append these dns suffixes and you should be able to resolve internal names once again.

You can also set the primary dns suffix of that computer in properties of my computer, computer name tab, change button, more button, and then set the primary dns suffix of the computer there to be whatever the internal domain is.

Thank you for the answer this was exactly what was happening, I added my domain name to the append list and everything works as expected!
