Intermittent network errors - NT/2000 server is out of licences changed

Question

Shares and network resources are not accessible from workstations.

Cause

This is caused by the server rejecting the request for a network resource from a workstation. This failure to access the network usually goes unnoticed by the workstation but may result in the problems above. Each time the server rejects a licence request it writes an entry in the Application Event Log.

If a consistent problem is encountered, it can be tested by logging in as a user who is a member of the "Domain Admins" group, since license restrictions are not applied for Domain Admins. Check your server's Application Event Log for LicenseService entries:

Resolution

To resolve this issue, use Control Panel Licensing to add more server client access licences:

Instructions

Per Server Licensing: The number of client access licenses purchased is applied to a specific server. There is no restriction on who may use the server; the restriction is only on the number of clients that have simultaneous use of the server.

Per Seat Licensing: A client access license is purchased for each computer that obtains access to a server product. If you need to add an additional server for your licensed clients, you need to purchase a server license rather than more client licenses. See Windows help or documentation for more information about licensing modes. Contact your Microsoft dealer for licensing information.
