Fine-tune printer permissions
By default, when you share a printer in Windows 2000 Professional, all users have at least some access to the printer. All users can print to the printer, and members of the Power Users group can print documents, manage documents, and manage the printer. These latter two permissions enable users to manage individual documents in the print queue and manage the queue and printer itself.
In a small network, the default permissions are usually sufficient. But in a larger network or one where you need to further restrict access to printers, you'll probably want to fine-tune the printer permissions.
You can configure printer permissions via the printer's properties. Open the Printers folder, right-click the printer, and choose Properties. The Security tab lists the groups that have printer permissions. To view the permissions for a group, click the group, and Windows lists the permissions in the Permission section.
To prevent all users from being able to print, remove the Everyone group from the list. And unless you want users to be able to manage the printer and documents, remove the Power Users group.
Add groups as needed, and select permissions for the group to control access. Keep in mind that you can set each of the three printer permissions to either Allow or Deny. Setting a permission to Deny prevents a member of that group from using the permission, even if membership in another group allows the permission.
Install service packs individually on cluster nodes
Membership in a cluster doesn't mean that updating a single node in the cluster will automatically update the server. Rather, you must install service packs and other updates individually on the nodes in the cluster. Doing so, however, can be a fairly painless process if you follow the right steps.
Begin by making sure you have adequate backups and other safeguards in place so you'll be able to recover data and/or servers in the event of an unforeseen problem with the upgrade process.
When you're ready to upgrade the first node in the cluster, open Cluster Administrator, right-click the node, and choose Pause Node. After pausing the node, right-click it, and choose Move Group. Move all of the groups on the node to another node in the cluster.
After moving the groups, install the service pack on the node, and restart the computer. Check the event logs to identify any potential problems, and address any problems that come up.
After you've properly updated the node, open Cluster Administrator again, and choose Resume Node. Then, move back groups to the node as needed. Repeat this process on other nodes in the cluster one at a time.
