JSI Tip 0619 - You installed a full retail Windows NT Server over an NFR Server but can't connect more than 10 clients.

Use Regedt32 to navigate to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters\Users

Double-click the Users value name, a data type of REG_DWORD, and change the value from 10 (Hex 0a), to Hex FFFFFFFF.

You will need to reboot the server for this change to take effect.

Note: You can not use the NFR Setup diskettes. Discard these and only use the full retail ones when performing an update or repair. If you lost these, run Winnt32 /OX or Winnt /OX from the retail server CD.

Note: You can not use a version upgrade to update an NFR version. It must be the full retail product.

Note: If you receive Evaluation Period Expires on Non-Evaluation Copy of Windows NT, see Q173507.
