This problem has come across on couple of customers who have upgraded their older ION Entperise software(IE5.0 SP5) to 5.6 on a Windows 2000 OS.
Everything works fine except the realtime value in Webreach. Even the historical data in Webreach works, it is only the realtime value that shows blank values (not even N/A).
blank, empty, nothing, NA
The MDAC version of the OS is older than 2.8SP1.
How to check for MDAC version:
Please refer to Microsoft kb#301202 or use the link below.
Update the MDAC version to 2.8SP1.
