Domain Environment

When the History DA Server and Client PC are in same domain
Ensure that domain user accounts are used for running the OPC Server as well as
OPC Client. So, in this case, no need to create users in each PC (as it is done in
workgroup environment.)
Ensure that the user account is set properly for DCOM settings. For example, the
username in case of domain user account will be like 'DomainName\Username'.
Before doing the DCOM settings, please make sure that both the OPC Server and
the OPC Client are running with the same domain user account.
If the local user account is used for DCOM settings, then this user account should
be consistent in Server and Client PC.

There should be a common user account for running both OPC Server and OPC
Client.
If the OPC Server and OPC Client are running with different user account,
then, these local user accounts should be available in both PC. For example, if
the OPC Server runs with local user account 'A' and OPC Client runs with user
account 'B' then both local user 'A' and 'B' should be available in OPC Server
(For example, History Server Node) as well as OPC Client Node. It is not
mandatory that these user account have same password.
