Is this a Windows XP system you are testing on, or a Vista system? I have had issues running anything from a UNC path within the Command Line window in the past. If it isn't the UNC path, it could be that whatever location the cmd is running from needs to have some sort of authentication to gain access to the cmd. Test the command itself by running it from a command line on your test box. At the very least, it may give you an error that will tell you what the problem is. |
