Hi, What the error code or message you get in your issue? Is there some event logs related to the issue? You may run net use command. For example: To assign the disk-drive device name E: to the Letters shared directory on the \\Financial server, type: net use e: \\financial\letters Meanwhile, please open an elevated command and refresh DNS and reset Winsock. >ipconfig /flushdns >netsh winsock reset Net Use command http://technet.microsoft.com/en-us/library/bb490717.aspx I suggest you post the error code or event logs in the forum.

Error message: The mapped network drive could not be created because the following error has occurred: An extended error has occurred. Things I have checked: AD account Time/date on server and local machine User account can map them successfully on other PCs Only a problem when using the fully qualified path to the server. Mapping by IP address works. Flushed and re-populated DNS cache Rebooted multiple times Logon script that normally maps drives is correct Any ideas? Thanks, -Tom

Error message: The mapped network drive could not be created because the following error has occurred: An extended error has occurred. Ivan-Liu: That is the error message, word for word. It's not very helpful, is it. No code or description or anything. No event log that I can find (weird). Like I said, I already tried to flush DNS. Just tried to reset winsock and it didn't change anything, either. Net use produces the exact same results as mapping through windows explorer. Unfortunately I'm going to have to call this issue closed, it was the CEO's PC and he just got fed up and had us buy him a new one. He needed it anyways, the computer was pretty old and slow. Thanks for the help.

1. What you get when you issue net use * \\server\share 2. Would you catch the network traffic by network monitor.... 3. Are there any traces in Event logs? Regards Milos

Hi! This solved the problem for me: http://support.microsoft.com/kb/2686098 (When I did net use \\server\share I got this error: System error 2148073478 has occurred.) -Klaus
