Question/Problem Description
Users reporting error promsgs errno=22 on Windows 10 machine.

Microsoft Visual C++ Runtime Library error: Runtime Error! Program: N:\dlc\bin\prowin32.exe.

Problem did not occur on Windows 7.
 
Similar problems, identified through web searches, suggest that this may have been caused by a Windows 10 group policy setting.

Defect Number
Enhancement Number
Cause
The exact cause is not known at this time.

It is suspected that the mapped drives are being dropped by periodic changes to Group Policies.
The group policies are pushed out randomly and when the changes propagate to end-user systems the systems disconnect then reconnect the mapped drives but this causes the OpenEdge client connection to abort when it loses connection to its files / dlls.
 
Resolution
At the present time, two suggestion have been made:

1)  Using UNC drive mappings instead of Mapped Drives as UNC mappings are not reset by Group policy updates. For example,
\\servername\sharename

2)  Use login scripts on each client machine which set up the mapped drives instead of using Group Policies to push the definition of mapped drives to the end-user systems. For example,
net use <driveletterhere>: \\<servername>\<sharename> /persistent:yes

3) Install OpenEdge on the local system.
 
Workaround
Notes
Though the group policy was set to update, the problem does not stop when the policy is set to update. It appears that the disconnect occurs every time the group policy is updated.
