We are trying to implement DFS and we have run into some issues and unfortunately our domain name is the same as our external website. Is there a way to change the DFS name to something else? Our domain name is abc.com our external website is abc.com and the dfs is abc.com. Can we change the DFS namespace to XYZ.com?

Hello,

Domain based DFS makes use of the domain name, this cannot be changed.
You use a standalone DFS, however you will not be able to add any other namespace / folder paths from other servers to the DFS root.

Hi Michael,
Can you clarify what you mean? If i use standalone DFS it would work? Does that mean 1 server?

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Thanks a bunch. Is there a way to work around my problem besides changing the domain name if I still want to use DFS?

Hello,

Now I have no idea if this is supported, I certainly wouldn't think so...but you could as a work around use DNS. The DFS Namespace will still be domain based and incorporate the the domain name, if you had a DNS entry to point to the same IP address as your domain, and obviously use a nice friendly name you will still be able to access the folders.

Essentially like this:

Domain based = \\DOMAIN NAME\FILESERVER\Share

Create a DNS A Record, something like "Files", this will resolve to the same IP's of your domain, if you have more than 1 DC simply create a record for each, when accessing the DFS namespace, the below will work.

\\FILES\FILESERVER\Share.

Again, I have no idea if this is supported, and please test this before implementing!

Regards

Michael

Is your DNS split-brained (external DNS hosting)?  

Internal DNS (and DFS) only needs \\domain.TLD\ to work properly.  Internally, your website should not be accessible using http://domain.TLD, otherwise you would have other AD problems since all of your domain controllers should be the only hosts available using domain.TLD.  Internally, you should only be accessing the external site as http://www.domain.TLD, so AD and DFS should work just fine.

Things get a little more complicated if you're doing VPN from outside, but one step at at time.

We have our own dns servers internally. You are correct about the resolution of the domain. I guess the problem is that on certain work stations the dfs resolves to our exchange server/webmail server instead of the DFS.

Do you have more than the IPs of domain controllers in the list of HOST records for your domain?  If you do an nslookup on the domain name, are the Exchange (webmail) server IPs listed?

nslookup domain.tld
