Load Balance the workload across 3 Domain Contollers

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 ?

Hi Aaron


                   After increased the weight from 100 to 200 on DC4, i see 100 and 200 records display together for DC4, is it correct ? and on which DC i should modify the weight ? on the DC where has FSMO running ?

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.

shall i delete all of the record weight 100 from hk-dc4 ? next time shall i modify the weight in the DC where running fsmo ? or it doesnt really matter can modify on any dc ?

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
