Hi,

Some months ago I had the same issue and the solution was to modify the "host" file, which is located at "C:\Windows\System32\drivers\etc"

What you have to do is:

1.- Edit the host file with the explicit IP Address and the Host Name of your App Station or OS Station from whcih you read the historical records.
2.- In the Process History View you need to use the Host Name instead of the explicit IP Address.

Host file Example:

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
#
10.4.0.52 App_Stat
10.4.0.76 OS_Station1

I suggest to do this in all the computers that have to get connection to historical database.

I hope this help with your issue.

Regards,
Marcos Moreno

In reply to Marcos Moreno:

We modified the Host file as well to contain primary and secondary IP's (10.4... & 10.8...) of our Pro+ (events) and App Station (Historian). PHV worked fine after.

Host file Example:

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
#
10.4.0.## App_Stat
10.8.0.## App Stat
10.4.0.## Pro+
10.8.0.## Pro+


Good Luck
