Ok so if you have ever had this problem you know how really annoying it can be... You try to map a drive and you get this:
The Network folder specified is currently mapped using a different user name and password.
You check your drives and there are NO Mapped drives to that computer at ALL! I have had this problem many times and one thing I found to fix it was to try and map the drive using the IP-address instead of the computer name... Well what if that fails? Go crazy and try a million things until it works. Thats what I have always been forced to do until today! I finally found a solution (now granted this might not always be the problem, but I have a suspicion that it is the culprit more then not)...
So I was working on this very problem and thought I would try the "net use" command in the command line... And I saw something interesting... There was a resource connected... IPC$ was connected... So I deleted that resource with "net use (resource name) /delete" and that did it! That fixed the problem and I was able to map the drive no problem... I think that IPC$ is used when you browse to the computer with network neighborhood but I'm not sure... I feel so much better now that I know what has been happening all of those frustrating hours I have fought this problem!
Run command prompt as administrator:
cmd> net use
cmd> net use /delete \\server\share
