For the installation of WinCC, certain requirements with regard to the operating
system and the software configuration have to be met. Before the installation of
WinCC, the MS Message Queuing Services and the SQL Server 2000 instance
"WinCC" need to be installed.
Caution
WinCC has been approved for operation in a domain or working group.
However, please note that the domain group guidelines and domain restrictions
could hinder the installation. In this case, delete Microsoft Message Queuing,
Microsoft SQL Server 2000 and WinCC from the domains from the computer prior
to the installation. Following a successful installation, the WinCC computer can be
readmitted to the domain. If the domain guidelines and domain restrictions do not
interfere with the installation, the computer need no be removed from the domain
during installation.
Please note that the domain group guidelines and domain restrictions could also
interfere with the operation. If these restrictions cannot be cleared, operate the
WinCC computer in a working group.
If necessary, contact the domain administrator.
