I am able to ping the server running server 2008 r2 and also able to connect to the remote desktop to the server. However unable to access the folders in the server like \10.0.0.100foldername or server1foldername. Previously it is accessible and we are were running hms application in that. All off sudden in a morning it is not working. When try to access the server folder by server1foldername or \10.0.0.100foldername getting error network path not found. What could be the problem?
