I made a SCADA on LV8.5+DSC consists of two parts: first - data asquisition and data logging in Citadel, second - HMI (client, connected with first program by psp protocol).
I create in LV Domain Security Manager two account: User and SuperUser in Operators group (simplest case). I try use security domain account to limit access on same HMI function.When I develop both programs I log in Windows XP as Admin (Administrator group) and all worked as it necessary. I build stand-alone application both first and second parts from successful.
Then I create on my WinXP an user, named Operator (users group). I try execute my both program as Operator and have a problem. Both Programs worked, but NI Tagger Service stopped, when i try to change User and SuperUser accounts. Why?
Execuse my bad english

Thank you, Brian!
I don't understand a difference by NI Security Domain and WinXP Security Service. I suppose, that NI Domain independent from WinXP.
Therefore, in my case, real WinXP user (Admin and Operator) and NI Security Domain (User and SuperUser) not equal.
May be, I must create same users as WinXP as NI Security Domain?

First, let me make sure I understand the situation correctly. You have 2 users configured in your NI Domain. When you log into XP as Administrator, then log into the NI Domain with either of these users, you see expected behavior. However, when you log into XP as some other user, then log into the NI Domain as one of the 2 users, there is a problem?
What exactly is the problem you are seeing? Do you see any error messages? You say this is related to the tagger service. What settings do you have in LabVIEW in the Options, under Security in the "Current shared variable engine user" field?

You are right.

I have default settings "nobody". I read LabVIEW hel, but understand this theme no.
Thank you!
