Error Mapping or Reconnecting Network Resource

This article was previously published under Q130077
SYMPTOMS
You may receive one of the following error messages when Windows istrying to reconnect a mapped network drive or when you try to map a driveto a network resource in Windows Explorer:
  • The following error occurred while reconnecting X: to \\<server>\<share>
    Invalid local device.
    Do you want to restore this connection the next time you log on?
  • The following error occurred while reconnecting X: to \\server\sys
    Permanent connection not available
    Do you want to restore this connection the next time you log on?
  • The following error occurred while trying to connect X: to \\<server>\ <share>
    Invalid local device
  • The following error occurred while trying to connect X: to \\server\sys
    Device not connected.
where \\<server>\<share> is a shared Microsoft resource and \\server\sysis a shared resource on a NetWare server.
CAUSE
This error can occur if the drive letter you are trying to map is higherthan the last drive available to Windows. The last drive available toWindows is defined in the LASTDRIVE= statement in the CONFIG.SYS file.For example, this error occurs if you try to map drive Q, but theCONFIG.SYS file contains the statement LASTDRIVE=P.
RESOLUTION
To work around this problem, use any one of the following methods:

  • Remove the LASTDRIVE= statement from the CONFIG.SYS file.
  • Modify the LASTDRIVE= statement in the CONFIG.SYS file so that the last drive available to Windows is greater than the last drive letter you want to map.
  • Map a drive letter that is less than the last drive available to Windows instead of the drive letter you are trying to map. For example, if the last drive letter available to Windows is drive P, map drive O to the network resource.
STATUS
Microsoft is researching this problem and will post new information herein the Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
When you use the protected-mode network clients included with Windows(VREDIR.VXD and NWREDIR.VXD), avoid using the LASTDRIVE= statement in theCONFIG.SYS file. If you use a LASTDRIVE= statement, avoid mapping a driveletter that is greater than the drive letter in the LASTDRIVE= statement.
