Hi,
I'm trying to call a number of XML SQL Management Policy files using a remote network path e.g.
Invoke-PolicyEvaluation -TargetServer "instancename" -Policy "\\servername\policy.xml"
This results in an XML error:
Invoke-PolicyEvaluation : File '.....' does not have a valid XML format that can be deserialized to a policy.
When using a local path or a mapped path it works correctly e.g.
Invoke-PolicyEvaluation -TargetServer "instancename" -Policy "C:\policy.xml"
Can anyone explain this error. I really need to use a shared location for storing SQL policy files.
Any feedback is appreciated.

Anything on this? I too am having the exact same issue. It makes no sense to me why reading the file from a network share should be any different than reading from a local folder.

look at https://docs.microsoft.com/en-us/powershell/sqlserver/sqlserver-module/vlatest/invoke-policyevaluation

Although the examples there do not use a network share, the Get-ChildItem can get them from there with no issues, and you pipe the file onto Invoke-PolicyEvaluation

e.g. get-childitem networked_xmlfile|Invoke-PolicyEvaluation -TargetServer "MYCOMPUTER"

or even
get-item networked_xmlfile|Invoke-PolicyEvaluation -TargetServer "MYCOMPUTER"

frederico_fonseca, thanks for the suggestion.

In my PowerShell, I went with mapping a local drive to a shared location and referencing the policy files from the new local drive but I don't like the solution.

Going to try your method.

Nope. Policies just can't be read correctly from a shared location.

Set-Location "\\pathToPolicyfiles"
get-item "policy.xml" | Invoke-PolicyEvaluation -TargetServer "servername"
ERROR: does not have a valid XML format that can be deserialized to a policy.

Back to using a mapped drive for me.

does this work? without setting location

get-item "\\pathToPolicyfiles\policy.xml" | Invoke-PolicyEvaluation -TargetServer "servername"
