[gaz91au]

sorry @eaarora-ms , i just edited my above post to show logs which contain The parameter is incorrect. error.

[gaz91au]

@eaarora-ms if it helps, this is my task yaml

steps:
- task: IISWebAppManagementOnMachineGroup@0
  displayName: 'Update Website Physical Path'
  inputs:
    WebsiteName: alpha.thedocyard.co
    WebsitePhysicalPath: '\\$(AzureShare)\$(WebsiteName)\$(Build.BuildNumber)'
    WebsitePhysicalPathAuth: WebsiteWindowsAuth
    WebsiteAuthUserName: '$(AzureShareUsername)'
    WebsiteAuthUserPassword: '$(AzureSharePassword)'
    WindowsAuthenticationForWebsite: false 

[eaarora-ms]

@gaz91au Mostly this error occurs when your IIS website is not assigned to a valid application pool. Can you please verify that the default app pool exists and let us know?
Also, can you try using the Create/Update App pool option from the task and let us know the results?

[gaz91au]

@eaarora-ms i can confirm that the IIS Website already is up and running and has a valid application pool assigned to it.

Im hesitant to use Create/Update App pool because ive already got a valid application pool and dont want to override any existing settings.

[eaarora-ms]

@gaz91au Can you please try restarting the IIS Website and let us know the result?

[gaz91au]

@eaarora-ms still getting the same error after restarting the IIS Website

[ChrisFulstow]

@gaz91au does the path \\AzureFileShare\Website\1.1.0 already exist? Could it be trying to create the directory but not have permissions? Just looking at the log:
##[debug] Creating website physical path \\AzureFileShare\Website\1.1.0

[gaz91au]

@ChrisFulstow yes \\AzureFileShare\Website\1.1.0 exists.

[gaz91au]

@ChrisFulstow @eaarora-ms Its definitely a permissions issue, im using the VMSS TeamServicesAgent Extension which executes this pipeline on VMSS instances and when it checks if the path exists, it fails to find the path. Is it because its trying to check a path that is a authenticated Azure File Share path?

• ##[debug]Checking website physical path exists \\AzureFileShare\Website\1.1.0

Heres my TeamServicesAgent Settings:

{
  "VSTSAccountUrl": "https://dev.azure.com/tdydev",
  "TeamProject": "tdyapp",
  "DeploymentGroup": "alpha-vmss-aue",
  "AgentName": "",
  "Tags": ""
}

[ChrisFulstow]

@gaz91au I'm pretty sure this task does a Test-Path to first check whether the physical path exists before updating IIS. Which credentials is it using to connect to the file share? I think it should be:

WebsiteAuthUserName: AZURE\<storage-account-name>
WebsiteAuthUserPassword: <storage-account-access-key>

[gaz91au]

@ChrisFulstow It fails at Test-Path, Ive updated the task to use AZURE\<storage-account-name> but that didnt fix it.

One thing to note is that im using the VMSS Azure Agent Extension, and it installs the agent under NT AUTHROTY\SYSTEM user, which i think doesnt have permissions to do the Test-File.

When i remote into the VMSS Instance as an admin and manuially do a Test-File \\AzureShare\Website\1.1.0 it returns True. So i think this its definitely an permissions issue.

@eaarora-ms Is there any way i can install the VMSS Azure Agent Extension as an admin user?
