Our office has 2 servers, 1 is windows 2000 the other 2011 smb essentials. I have about 8 windows 7 machines in the office. They all access both servers without issue. That was until earlier this week. One of the machines began having issues saving to network shares on the server running windows 2011 essentials. The problem started with excel then spread to all programs. I can access the drives fine, no permission issues or lag. I can copy and paste / drag and drop files to the network shares with no lag or issues.
It is only when you try to save a file from a program such as notepad, word, excel, etc. directly to the network share does the process either have incredible lag, ( saving a 1 kb notepad file takes almost a full minute ) or fails completely and reports that the file is already open. I have removed the machine from the domain and re added it. I even went as far as to plug in a new hard drive and re-install windows 7 and rejoin the domain and the problem continues. I also tried changing the NIC and no change.
I am hesitant to go into the registry on my new server to disable SMB 2.0, i feel if this was the issue then other Windows 7 machines would be affected. Does anyone have any ideas?
