Hello Yann,
this is usual and happens because Site B was configured in Active Directory before DC B was there and assigned to that site. Automatic Site Coverage is the process which is taking care of this effect. What it does, is making sure that every site in Active Directory has DCs. If a DC detects a site which has no DCs assigned to it, it will try to figure out if hes a close DC (not crossing multiple site-links) and assigning himself to that site. So since Site B was configured and DC A was the only DC in your environment, DC A decided to advertise himself as DC in Site B. However since DC B exists now, DC A will not refresh those records, and if you have aging and scavenging configured the old records of DC A in Site B will vanish. You can also delete those records if you wish, as long as the records of DC B are registered in Site B you can delete the records of DC A in Site B, however make sure that you are only deleting the SRV-Records underneath the DNS-Subdomains of the Site-specific Records in the Site B-DNS-Domains (looks like folders in the DNS Managementconsole).

Januar 2007 22:28 To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Question about DNS SRV registration. Hello all and happy new year:-), Say: -> Site A with DCa that is also dns (integrated to AD). -> Site B that is a new site. my goal: dcpromo a new DC (DCb) in site B.DCb will be also dns (integrated to AD). -> DCa & DCb belong to the same domain (domain.local). My AD is w2k3 FFL mode. In order to add the new DCb in the existing domain.com, DCb is dns client to DCa. When dcpromo is finished, i configured: - DCb as dns client for himself - DCa as secondary dns sever for DCb. Everything looks good .. BUT: When clients in site B ask for all DCs in site B (with netlogon process),DCb returns DCb and DCa ! a nslookup set type=srv _ldap._tcp.siteB._sites.domain.local shows the 2 DCs -> DCa.domain.local -> DCb.domain.local When i search in dns console, i found that DCa still present in site B, i think, this is due to the fact that DCb's nic allow dynamic update and thus dynamically records DCa srv records. The only way i found to avoid DCb returning DCa to clients in site B is to delete srv records for DCa in dns (site B). Question: What is the best practice to avoid DCb to return DCa to clients and where in the process i'm wrong ?
