Randomly having trouble connecting to DFS over my network. &nbsp;Everything was working great for about a year. &nbsp;Users could connect to \\domain\DFSshare or \\domain.local\DFSshare without issue.<br />
<br />
About a month ago the domain functional level was raised to 2008R2. Now I seem to have connection issues with NetBIOS or dns depending on how the user mapped the drive.<br />
<br />
Received a bunch of calls this morning that mapped drives could not be found. &nbsp;Two of the calls were laptops right next to each other. Laptop1 using <i>\domain\DFSshare </i>and Laptop2 using <i>\\domain.local\DFSshare</i>. &nbsp;<br />
<br />
I tried flushing DNS on both with no luck. On Laptop1 I disconnected the drive maps and reconnected them using <i>domain.local</i> instead of <i>domain</i>. On laptop2 I had to do the opposite to connect.<br />
<br />
Occasionally IPCONFIG /RELEASE and a reboot would fix but not always.<br />
<br />
Anyone have any ideas on troubleshooting this?

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
