Figure 3.6.1-7 Access permission Security Limits Anonymous
If the server computer is running on Windows XP, the default
installation for XP forces remote users to authenticate as
Guest. This means that DCOM clients cannot connect to a
server running on an XP computer, unless the Guest account
is enabled and has enough rights to launch the server.
To adjust the setting in the control panel:
1.
Click Start > Control Panel > Administrative Tools.
2.
Open the Local Security Settings window.
3.
Expand the tree view and select Security Options in the left-hand pane.
4.
In the right-hand pane, scroll down and select Network Access: Sharing and
security settings for local accounts.
5.
Right-click and select Properties.
6.
Select Classic - local users authenticate as themselves.
More information about setting up the DCOM can be found from the Microsoft and OPC
Foundation internet sites. OPC Foundation has published a number of reports about using
OPC via DCOM, which can be downloaded from their internet site (www.opcfounda-
tion.org).
