Yesterday we started seeing issues with saving Excel files on network drives. When users try to save them they get "Document Not Saved" and even if they do a save as to overwrite it they get the same message. If they save it locally then they can replace it and it works fine.
I restarted the file server yesterday and it worked fine after that until this morning, now the error is back.
Anyone know what causes this? Is there a temp folder on the server or anything that needs to be emptied?
I've read through a lot of KB articles talking about certain updates causing it but I don't have any of those updates installed on my computer or the server.
Using Windows Server 2008R2 and Windows 7
I just tried a word doc and it says "there has been a network of file permission error, the connection may be lost"
