Can't copy/move files to network share

[sirjeff2000]

Hello, I am using Windows 7 Premium and can no longer copy or move files to shares on a windows 2003 server. Also, I can not save documents to the mapped network shares either. This was working at one time, but has since stopped.
It stopped when the server was disconnected from the network switch. The user was trying to save a document to one of the mapped network shares and received message that this was impossible. Once the server reconnected, the Windows 7 workstation could connect to the mapped shares and open files but could not copy the saved file to the mapped network share. I receive the following error when trying to copy a file from my local drive. There is a problem accessing (path to local file) Please check your network connection etc..etc.. The workgroup is set correctly. and as I mentioned before everything worked until the day the server was disconnected. the user has the same authentication parameters on both the server and the work station.

I tried removing the user from the server permissions then adding them back.
I ran registry mechanic.
I tried a system restore from the day previous to the server loss.



What I can do.
1.Create a new file/folder on the same network shares in question.
2. If I create a new text file on the desktop I'm able to copy as expected...strange but true..I looked at the permissions on the newly created file and they are the same as all the other files I'm trying to copy.

I know you checked, but I can't help but feel this is a permissions issue.

What if you open a problem file and "save as" to the desktop?

As a matter of fact, I tried that as well. It would appear to be permissions based. What I would really like to know is why that would happen. On the network shares, I use either a group permission or an individual permission. I tested this problem across all mapped shared drives. I could create a notepad file and save it to the network share but two files one a publisher file and one an excell file which were saved to the desktop could not be copied, moved or opened and "saved as".

Don't ask me why this worked BUT it did!

After googleing for a solution to this problem, I read several posts that pointed to a bad network card. I was not convinced the card was bad since it connected to the network and could send and receive email etc. Having exhausted all attempts to reset security permissions to the network shares, and verifying that this problem affected all users on the computer, I speculated on the possibility that something was wrong with the switch used to connect that particular computer to the rest of the network. I powered off the switch(3Com Superstack II - unmanaged switch) waited 10 seconds, powered on the switch - problem solved.
