SYSVOL referrals.

[TheMisio]

Dear Techies,

I have come across a weird issue. We have an AD 2003 domain spanning several sites. We have sites and services configured with all subnets etc. The issue we have been having is that clients are getting SYSVOL referrals to servers in different AD sites, causing logon performance issues.

I have enabled site costed referrals as per MS article:

http://support.microsoft.com/kb/905846

However, having restarted all DCs and allowing over 48 hours, clients are still getting SYSVOL referrals of various, random AD sites instead of the authenticating DC.

Does anyone have any idea why? It just doesn’t make any sense to me that a client logging on to the AD network, would be authenticated by a DC in site A, but would get a SYSVIL referral to site B.

Regards.

Michael

Are all of your DC's Global Catalogs?

TechyMcSe2k,

Yes. All of our DCs are GCs.

Where does the primary DNS on your site DC's point to? Also, the client IP's handed out by DHCP, I assume for each site, do they use the local DC as their Primary DNS?

Check your site link costs:

Make the Default a much higher Cost to make the DC's use the site links you create. Make a site link for each site and put the site DC and just the root DC's (from your central AD site) This way the replication is only between those two sites.
