Subject: RE : [ActiveDir] Load balancing LDAP request among my DCs -> Corre ction :)"busy" in term of all queries (LDAP, auth...) point to only one DC, that causes heavy load.These loads cause affected system resources (memory, CPU, ..).All my DCs have the same system resources (1Go RAM, biprocessor,etc..).When monitoring DCs queries, always the same DC suffers of these queries ;(Maybe, I have this simple picture of load balancing in my mind...1 DC receives plenty of queries(LDAP or auth) that it can not deserve efficiently. I imagine that it can forward a certain amount (a ratio ?) of those queries to another DC less "busy".. But maybe is a "to simple" reflexion :)Anyway, if DCs can not load-balanced LDAP queries, i will then chek your link and altering SRV record weights/priorities in DNS.Regards,Yann

Objet : RE: [ActiveDir] Load balancing LDAP request among my DCs -> Corre ction :)Well, yes and no. DNS does load balance via round robin, as Jorge alluded to. DCs do not load balance based upon your requirements, where a request is forwarded to another DC if the receiver is "busy".
After all, what is the definition of busy??

Ok, thanks for the reply. Your tip might tell me that AD2003 seems to be *UNABLE* (and not enable -> sorry for my english :)) , natively, to load balance such queries, strange ...... :(
I will chek your link for more informations.
Cheers,
Yann

Have you considered altering SRV record weights/priorities in DNS?
Check out this article http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/Operations/df86810b-9fc5-49b8-a704-d01c042cf460.mspx - it may relate to the PDC but applies to DCs in general too.

Subject: [ActiveDir] Load balancing LDAP request among my DCs
Hello,
I have a site with 4 DCs 2003.
It seems that one of my DC can not deal with a large number of LDAP queries, GC Response and NTLM/Kerberos Auth .... I misunderstand something but is my DC 2003 is able to check that it cannot deserve these queries and forward automatically these queries to another DC that is less busy ? In order wold, can AD 2003 natively load-balance queries to another less busy DC ? Regards, Yann
