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).
