Hi All

     I have 3 DC with server 2008 in my company, with DNS, DHCP, File server roles operating on one of the DC, just wonder is there any way to load balance the 3 DC ? for below screenshot, if i put the weight for example 300 to the DC that i want to load balance the workload to, is it correct ? because i have installed a 3rd DC, to load balance the workload for the other 2 DC, is there any other way to achieve that as well ? also to change the DNS from all client computer, to point to the new installed DC, hope you can help , thanks !

Dhcp load balances easy. It's an option to round robin in 2012, pretty sure 2008 is the same. DNS is normally done as a primary and a secondary from DHcp or static. You can put them in reverse order but most clients only swap DNS servers when one fails and only fail back if the other one fails.

I don't do file sharing roles so I can't help with that.

How about the screenshot that I attached, can I increase the weight so that client will find this DC more often than the rest of the DC ?

Active directory should replicate the DNS to all servers. You are using active directory integrated zones right?

yes, but i just wondering and it will display as two records of hk-dc4 (100 & 200) from _gc and the rest as well, in this case it will use the 200 weight ?

This is starting to get over my head, I have not seen this before. If I had to guess, I would assume that one of the other dc is out of sync and still putting out the 100 weight record. I don't think having a second record will hurt but the out if sync dc may cause other problems if I'm right.

Are your end users making ugly email signatures?

Have you left it up to your end users to create their own email signatures? Are they forgetting to add the company logo or using garish font colors? Take control and ensure all users have the same email signature.

I can't say for sure. I will say that what we are messing with won't break anything for your users so it's not crazy important to do it exactly right.

Is suggest making the change on your fsmo dc and making sure all your DCs running DNS are In sync.

You are not supposed to have duplicate records, I don't know which one will take precedence.

Either your DNS is not active directory integrated or one of your DNS servers is out of sync
