How do you configure a \\domain\sharedFolder in windows 2008?

Background:

• I've got several Windows 2008 servers setup by someone else.
• They are all on one domain, lets call this mydomain
• Several boxes are accessing a shared folder by going to \\mydomain\share1
• I found the actual files backing the share on box1
• I need to move the location of this share to a larger drive for space reasons

I'm familiar with setting up and managing shares like \\box1\share1, but where do you manage/configure shares that are domain-wide; accessed like \\mydomain\share1 ?

It sounds like you have a domain based DFS configured, which is managed by the DFS Management utility.

DFS is Windows Distributed File System feature. It allows you to apply a virtual path overtop of a physical path. A great feature that allows the movement of shares between servers without the apparent path changing. It also allows for multiple copies, and redundancy.

More about DFS can be found here: http://technet.microsoft.com/en-us/library/cc757042(WS.10).aspx

As Bryan says the DFS Mgmt utility is where to go to make changes. You may want to read a bit and test any changes before trying it live.
