A. When the NetWare migration tool (nwconv.exe) is run it tries to establish a connection to the domain controller, or specifically the ADMIN$ share. If it fails the error:

Cannot connect to server: <servername>
The Network name cannot be found

The Admin$ share can be disabled by setting AutoShareServer to 0 on the domain controller. To fix this perform the following:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
  3. Double click on AutoShareServer and set to 1. Click OK
  4. Close the registry editor

You should now reboot however if that is not convenient just type

C:\> net share admin$

which will create the share now and thanks to the registry change it will also be created at reboot time.

If AutoShareServer was already 1 or did not exist the it may be just admin$ has been corrupted so again type the command

C:\> net share admin$

to recreate.
