远程Powershell访问被拒绝

Question

I have a SQL Server database with some tables and a trigger, the trigger would create either FolderA on ServerA or FolderB on ServerB, this is the command I pass in the trigger for ServerA:

SET @folder = 'powershell.exe  invoke-command -computername ServerA { powershell.exe  -NoProfile -ExecutionPolicy Bypass  -File C:\FolderScript\FolderA.ps1 "' +@folderName+'" }'

EXEC master.dbo.xp_cmdshell @folder

I have an intermittent issues with it, it will work just fine for couple of days before it stops then I would have to run it manually from PS on ServerA.

Because it's intermittent, then we can rule out firewall, permissions, PowerShell enable remote. I have a web based application (asp.net) that users run from their machines and it connect to the SQL Server database where the trigger is located.

Is there some sort of sessions that needs to stay open to prevent access denied error? I can't think of anything else that might cause this issue?

Answer 1

I suspect the issue is with your quoting happening in the command:

SET @folder = 'powershell.exe -Command "Invoke-Command -ComputerName ServerA { & ''C:\FolderScript\FolderA.ps1'' ' + @folderName + ' }"'

This should be sufficient to resolve your issue. You do not need to repeatedly call powershell.exe as you can natively call scripts with the call operator ( & ).
