This would eliminate all of the potential routing involved. Aquinas, thanks for the link Sorry, just trying to better understand what I'm troubleshooting. You are correct on your statement. I'm wondering if the issue may be that their "home" network is using Since you have split tunneling, it may be trying to hit a "home" IP address that is not responding because it doesn't exist on their "home" network or is another device that doesn't provide DNS.

I'm pretty sure only geeks like me use class A addressing at home, but just to be sure, I double-checked with another tech here who was once getting good DNS but one day it suddenly stopped working with no perceptible changes being made to the firewall or DNS server here. He is using a typical The good part about that though is I can test any changes I make with him to see if they've made an impact.

He has the same ISP as me, uses the same home router, and even the same model laptop. I've never had a problem with DNS while his now won't work at all. He has to put everything in his hosts file if he wants to connect to anything by name. That points me in another direction. COM both internal and external?

I had a similiar problem with my Exchange server, because it was both on the internet and internal, with the same DNS name available. When I VPNd in, i would have to have the host file have the server name in it with the internal address.

This allowed the laptop to know which direction to look for the server. Funny that you bring that up. COM, was owned by someone else externally. I did my best to convince the company to purchase that domain, but the owner knew we wanted it and wanted a ridiculous price which we would not pay. COM points to their public IP. So anytime someone trys to connect to, say exchange. COM could be anything, crm. We've decided that rebuilding the domain isn't an option, so all I can really do at this point is try to make our internal DNS function when someone is connected to our VPN, because if they aren't , anything.

COM will resolve to this other public IP that we don't own. You can see how this presents a serious security issue for us. I mean, if someone pulls up their Outlook outside of the office without being connected to VPN, they are potentially sending their creds to this IP. I'm trying to get away from this, however, because if we change the IP address of the server providing the service, it breaks for that user until we can edit their hosts file.

As it turns out, we're about to upgrade to Exchange and we will be changing the IP address. Sorry for the lengthly explanation, but the bottom line is that host files are a temp fix for us, but not flexible enough to be a solution. Just can't figure out what to do I found this article: If you could do what the author did in the first portion about showing ipconfig and nslookup on a working and non working client, that would help us to determine where the problem lies.

I'm wondering, based on this article, if the issue is that the local DNS address from the provider are taking precedence over your VPN assigned addresses. Experts Exchange Solution brought to you by Your issues matter to us. Thanks very much Aquinas, this is good info.

I will try to head over to the tech's house who has the DNS issue and will compare to what I get at home. Will post back after the weekend. Aquinas, this did the trick!! That article you posted got me to look at the network adapter binding order. When I looked at the machine that was having problems, sure enough, the wireless connection was set higher than the AnyConnect. Once I moved AnyConnect to the top of the list, problem solved!

For someone else wandering into this topic looking for a solution to the same type of issue, here is how you fix this on Windows 7. It's a little different on a different OS but just google for network adapter binding order or something like that.
