If you haven't already done so, check your subnet-to-site associations. Even though it may be unlikely to be the culprit, it should be quick and easy to rule out.

In my AD, I have 4 sites: HQ, Site1, Site2, Site3. My confusion (problem?) is with Site1. Site1 has 2 DCs (Win2008 R2 and Win2012 R2). I have IP Inter-Site Transports defined for: HQ <--> Site1 Site1 <--> Site2 Site3 <--> Site1 (there are other links, but these are the only ones that include Site1) So here's what's happening, for the 2 DCs in that site: DC1 (Win2008 R2) has links generated for itself to DC2 (Win2012 R2) DC1 <--> Site2 DC1 1st connection is understandable, it's to the other DC in the same site. 2nd Connection is understandable, there's a site link between this site and Site2. But why isn't there a connection back to HQ or Site3? Also (still in Site1): DC2 (Win2012 R2) has a link generated to DC1 in the same site. But no other links, to Site2, Site3 or HQ. (I do see a link from a DC in Site2 to this DC; I see no links from any DC in Site3 to any DC in this site. And I see no links from any DC in HQ to this site) Am I just misunderstanding, or shouldn't I have more links being generated? There's no link at all to any DC in Site3 or to HQ. Yet there are transports defined for it. Replication shows no errors. Site replication is scheduled for every 15 minutes. I even manually ran "repadmin /kcc" on each DC in this site, still no new links being generated. SO: am I just misunderstanding how the site links work? Shouldn't I have more links than what are being shown? Especially for the new DC2, which is only linking to the other DC in the same site, and no where else. DCDIAG is coming up with no errors. REPADMIN shows no errors. DNSLINT shows no error. Am I just misunderstanding?
