Have you see this error before?  Generally it occurs for me after I’ve changed my network password but had a previous network share open on a server using the old password.  Before I found the information below I usually just logged out or rebooted and it’s fixed the issue.  Recently I found myself in that situation again but I couldn’t reboot without losing a lot of data and I was crunched for time.  What could I do?  How did I get myself into this situation?  Unfortunately, I can be a bit lazy sometimes (which is a good thing when you write computer software for a living…  really Mom it is, trust me).  You see, I don’t like mapping drives to get to network shares.  Instead I almost always choose to use the UNC path and Windows Explorer (i.e. typing \\server\share directly into the address line of Windows Explorer) to connect directly to the share I need.  However, this can leave some things hanging around that may cause problems later.  Especially if your like me and don’t reboot all that often.  Here’s what I found when doing a Bing search…

This post from Travis Eperson (yes it was posted 4 years ago, thanks Travis!) helped me find the solution that didn’t involve logging off or booting.  Here’s the steps.

• From a command prompt type “Net Use” and enter.  Which will display a list of the network connections you’ve used or are using.  The ones where you’ve actually mapped a drive to you’ll see with a drive letter in the local column, but if you operate like me then that column will be blank since you haven’t really mapped any drive. 
• Find the one that you don’t need anymore, clip the details in the “remote” column and type “Net Use <remote> /delete” replacing the <remote> with the data you clipped.  if it contains spaces you might need to place the <remote> data inside quotes.

That’s it.  Now you should be able to connect to the network share using your new password.

Enjoy!
