RE: [ActiveDir] AD Sites and SYSVOL

Title: Message

The DC locator process is the job of DNS. Your zone records will contain the site-wide and domain-wide list of Domain Controllers. When a client tries to contact a DC, it looks first of all at the site-wide list in DNS and tries to contact a DC in it's own site. If this fails it will select one at random from the domain-wide list.

 

What is required here is some DNS tinkering, you need to manually delete the remote DC records from the domain-wide list on the branch office DNS server.

 

eg

 

Main Site DNS server:

Site-wide list contains SRV records for DC's in the main site

Domain-wide list contains SRV records for every DC in the domain

 

Branch DNS server 1:

Site-wide list contains SRV records for DC's in branch site 1

Domain-wide list contains SRV records for every DC in site 1 and the main site

 

Branch DNS server 2:

Site-wide list contains SRV records for DC's in branch site 2

Domain-wide list contains SRV records for every DC in site 2 and the main site

 

 

With this scenario, clients in the remote sites can only contact DC's in their own site or in the main site, not in another branch site which I think is what you are after.

Subject: [ActiveDir] AD Sites and SYSVOL

Hi Everyone,

In a large AD network (W2K SP3 + hotfixes) only the HUB DCs register the domain-specific SRV RRs and all DCs register the site-specific SRV RRs. When all DCs in a site fail the HUB DCs are contacted. Works as expected, at least for AD info. For SYSVOL info this does not work. When all DCs in a site fail the client enumerates all DCs that host the SYSVOL and it picks the first DC in the list (which is randomly created).

Is there any way to configure DCs so that the following situation exist:
* All DCs provide SYSVOL info for the clients in their respective site
* Only the HUB DCs provide SYSVOL info to clients in a specific site when all the DCs in that site are unavailable

Any comment on this appreciated

Thanx!

Regards,
Jorge
