As of yesterday, users are having issues trying to connect to the network via the network name. If you type in \\servername or try to open a mapped network drive, you cannot connect but it will work with the IP address. This is happening on Windows XP and 7 machines and the server is a Windows 2008 R2.
Sometimes if you don't do anything, after time it will start working again be itself. Otherwise as of right now if I flush the DNS, register the DNS, and reboot the computer, that will usually fix the problem. It happens to random people at random times.
Any ideas what I can do to fix this? Let me know if you have any questions...thanks!
