After you establish the remote access connection and you try to map the network drives, the operation may be unsuccessful, and you may receive the following error message:
The required authentication can be performed by following one of two methods:
- You can obtain a Kerberos protocol ticket when you attempt to map the drive.
- You can specify the credentials when you attempt to map the drive.
NOTE: To return to NTLM authentication (such as, when you attempt to access a Windows NT 4.0-based computer) the workstation must still be able to locate a (Kerberos) Key Distribution Center (KDC) in its domain, and then the workstation must be unable to obtain a ticket for the target server (that is expected when the target server is a Windows NT 4.0-based computer). If a KDC cannot be located, the computer does not return to NTLM.
Specifying the Credentials When You Map a Network Drive
- Right-click My Computer, and then click Map Network Drive.
- Map the drive letter and the folder.
- Click Connect using a different user name.
- Enter the credentials in the universal naming convention (UNC) "Domain\Username" format.
- In the password box, enter a password.
- Click OK.
