Frequently Asked Question

Why am I seeing "Error reading File" errors using Plato systems?

APPLICABLE AUDIENCE: PLATO Intranet Applications, United Kingdom and Australasia.

General Information

In Windows 10, intermittent "Error Reading File" (Error 1104) errors may be seen. Most often the affected file will be in the "Middle Tier" folder.

Usually this is caused by Group Policy drives set to "Recreate". Windows 10 automatically runs Group Policy updates in the background and disconnects/reconnects the drive to Recreate it. The error is seen while the drive is momentarily disconnected.


1) Change the affected drive to "Update" to prevent disconnections during use.
Many  facilities have central management of policies, but on a Windows 10 workstation you can check the Local Group Policy Editor by running "gpedit.msc" . Drive settings are at
User Configuration > Preferences > Windows Settings > Drive Maps .

2) Use IP address or UNC Path rather than mapped drive.
This is Plato's recommendation. Over many years, use of UNC path in particular has prevented or resolved many vexing network and infrastructure issues.
