Error when using API.DataWindow.Utilities.mShellAndWait: File not found

Question

I am trying to run a simple command using API.DataWindow.Utilities.mShellAndWait, however I am experiencing the following error in FDM web. Strangely, I do not see the same error when the command is run from FDM Workbench:
Error: File not found
At Line: ###
The command is as follows:
Dim strCMD
strCMD = "ECHO %DATE% %TIME% >> \\<servername>\<folder1>\<folder2>\File.Log"
API.DataWindow.Utilities.mShellAndWait strCMD, 0
This command works fine when run directly from the command line. I am using a UNC path so thought this would have worked. Can anyone please suggest how I can resolve this? I have also tried the following and this results in a similar error:
Dim strCMD
strCMD = "ECHO %DATE% %TIME% >> \\<servername>\<folder1>\<folder2>\File.Log"
Set WshShell = CreateObject("WScript.Shell")
Set WshShellExec = WshShell.Exec(strCMD)
Error: The system cannot find the file specified.

Answer 1

I would expect the issue is due to user access priviledges.
When you run it through Workbench, the shell and wait is using your (logged on user's) credentials.
When it operates through the web stie, it is using the service account credentials.
If the service account does not have permissions, that could explain the 'file not found', though I would expect an access is denied error.
