Security News > 2021 > April > Windows 10 update causing DNS and shared folder issues
Some Windows 10 users have issues with DNS resolution after installing the latest Windows 10 cumulative updates released this week.
As part of this week's April 2021 Patch Tuesday, Microsoft released the Windows 10 KB5001330 & KB5001337 cumulative updates to fix various security vulnerabilities and bugs discovered in the operating system.
Since installing the updates, some corporate users have reported having issues with DNS resolution that prevent access to shared folders on servers when trying to access them by the server's name.
If attempting to access the shared folder via the server's IP address, users can properly connect to the shared folders.
Since installing the latest cumulative updates, this policy prevents users from accessing their shared server folders.
"Best resolution we have found so far is the host file fix, the DNS service fix hasn't fixed any of them yet for us but was reported by someone else as a fix." - a Dentrix customer posted to our forums.
