I’m having trouble getting a net use map drive command to run on win 7 enterprise x64 (in a workgroup) that is trying to connect to a 2003 r2 box in a domain If I run net use z: \\sernername.domain.com\share /user: UserPrincipalName@upn password it doesn’t run and returns with System error 86 has occurred. The specified network password is not correct. But if run it via the GUI & select “connect using different credentials” or by using /user:domain\sAMAccountName password in the net use command instead it works perfectly. If I then go and delete the map drive (using net use z: /del) and then try the net use z: \\sernername.domain.com\share /user: UserPrincipalName@upn password it works fine I need to use UserPrincipalName@upn as users in my organization know their UserPrincipalName put not there sAMAccountName

hi i recommend you to try the following as i had the same issue with windows vista the syntax must be \\IP ADDRESS\share-name) not \\PCNAME\share-name and user must be PCNAME\username instead of UPN. Hope this will be helpful :) Abeer

And if your users have to enter their credentials anyway, why can't they resort to solely use the GUI - my users would never try to use the cmd windows on their own - instead they would be really annoyed, if they had to use a non-graphical user interface.

yeah i have tryed /user: sAMAccountName@domain.com and that works the problem is in our organization the UserPrincipalName is firstname.lastname eg john.citizen will the same account is first initial last name eg jcitizen. We also have a custom UPN suffix as the accounts could be held in one of several domains in the forest. The reason why I'm using a net use command and not the GUI is it's part of a script that maps a drive and then runs a command. this worked perfectly in XP but doesn't in win 7

Hi, Thanks for posting in Microsoft TechNet forums. As this issue occurs when using script, it is suggested to involve the Script Center for more accurate information.
