PiPutVal Returns "A call to SSPI fail"

Barry Hu

I have an Excel macro that's been working for years:

 

macroResult = Application.Run("PIPutVal", sTagname, valueCell, sTime, sServer, resultCell)

 

Recently I started to get an error from "macroResult" that says "A call to SSPI failed, see inner exception."

 

Does anyone know what that menas?

 

Thanks.

    I know this post is quite old, but for anyone coming here for the same reason, here's how I fixed this issue on my end.

    First, Open your AF Client (PI Sytstem Explorer) and go on the AF server Properties and add a space in the account box, as seen below:

    Voila!

    Works for AF Server access and PI OLEDB Enterprise as well. Might work in other scenarios.

    Don't ask me why, but it just work for me.

    Lets see what AVEVA can say about this 'work around'.

    Cheers,

    I faced exactly the same kind of issue after upgrading an AF server, fixed it with your trick (Seriously big thanks to you) and I'd be really glad to understand as well how this works...

    I mean, I'd gladly accept I messed up or missed out some SPN somewhere but how putting a space there could unlock anything is beyond me.

    Also, (Missing Content)​ , HOW did you find that ?
