74 RSLinx – Training Guide
Allow some or all domain users privileges to a specific application only
under DCOM configuration.
In order to do this Access control must be set to “user level” first under the access
control tab of network configuration. Go to Network Neighborhood and right click.
Choose properties and go to the access control tab. Select “user level access control.”
You must fill in a domain name in the text box. Enter the name of the domain from
which you wish to allow users access. You will have to reboot at this point.
Next go to the start menu and choose run. Type in “DCOMCNFG” and click OK. Go to
the Applications tab and choose the application you want to grant access to. Click the
properties button and go to the Security tab. Choose “use custom access permissions”
and click edit.
Click add and choose the domain from where you want to add users. Choose
“Everyone” from the list. This will grant all domain users DCOM access to this Windows
95 or 98 system.
• As an alternative, you may choose to add only specific users that you want to
grant access to this PC.
Next go to the default security tab and check the “Enable remote connection” check box.
Finally, go to the Default Properties tab and check the “Enable Distributed COM on this
computer” check box.
WIN NT
DCOM should install as part of Windows NT 4.0 or higher.
Since DCOM uses Windows NT security, there are several ways to enable a connection
between two PCs.
Use the same login on both PCs. The simplest way is to log into both PCs using the
same login. A domain login can be used like \\domain\username
or if using workgroups
a local account can be used like “username”.
Since using the same login on the server and client PCs may not be practical, there are
several other ways to enable DCOM between two PCs. All of these methods require
that a Primary Domain Controller exist on the network.
