Just to clarify my earlier statement: If your connection between the Ciscos isn’t 100% steady, it might take just those few millisecs too long for the VPN to get put up, especially if you’re going for more than the standard 3DES-MD5 sort and configure nifty requirements on the VPN.. in the meantime, your AD replication might just decide that the other site’s down.. and if your luck’s down, it’ll get the same result next replication time, etc, etc, I doubt I need to draw a picture.. Just something I ran across once at a customer and it was unnervingly annoying. :o)

On a few occasions I’ve seen this give some rather annoying results if the connection between the Cisco’s is not 100% reliable.

But if you’re gonna use the Cisco’s in a VPN Server – Client config with a decent line and there aren’t any restrictions firewall-wise, it should work decently. (Not 100% sure if the Cisco VPN Server – Client thing works with two 525’s, to be honest, we had a 3000 VPN Concentrator on the other side, so..)

Oh, and using the connection as ‘on demand’ should work alright, but if you can, put up a dedicated VPN instead.. when I say that it ‘should work alright’, it’s another one of those ‘perfect world’ scenarios.. ;)

Subject: [ActiveDir] AD Replication over VPN

 

Hello Collective List Wisdom ;)

 

I’ve just been tasked with setting up our AD to replicate over a Cisco Pix VPN. I’ve assembled some links now to various Microsoft articles and Cisco articles regarding most facets of what will be involved. What I’m looking for are any “Gotcha’s” from the real world versus the perfect one the writers of said articles tend to live in. Essentially setup is proposed as follows:

 

Here – 2 DC’s (Windows 2003 Server) and 2 Cisco 525’s (high availability)

Remote Site – 1 DC (Windows 2003 Server and 1 Cisco 525

VPN link between here and remote site for AD Replication, etc.

 

As I said earlier, I’m mostly looking for “notes from the field” covering things they DON’T tell you in most articles. I’m back to my light reading….
