PowerShell Dictionary

1.Create empty dictionary
$contacts = @{}

2.Add key,value item
## Way 1:
$key = 1
$value = 'CRM'
$contacts.add( $key, $value )

## Way 2:
$contacts.add( 2, 'C#' )

## Way 3:
$contacts[3]='.NET'

## Way 4 - Keys are just strings
$contacts = @{
    'full name' = 'C# Code'
    '#' = 1234
}
$contacts['full name'] # OR  $contacts.'full name' OR $key = 'full name' $contacts.$key
<#
    C# Code
#>

## Creating dictionary with values
$contacts = @{
    1 = 'CRM'
    2 = 'C#'
    31 = '.NET'
}
$contacts[4]='Azure'
$contacts[5]='Cloud'

## print contact dictionary

PowerShell – running scripts is disabled on this system.

When i execute powershell script from Windows PowerShell ISE, i got error, means PowerShell execution policy doesn't allow to run script.

Error
File TaskYearApp.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at
http://go.microsoft.com/fwlink/?LinkID=135170.
    + CategoryInfo          : SecurityError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnauthorizedAccess

First i want to see what's my execution policy settings, i run the below commands

PS G:\> get-executionpolicy
Restricted

So PowerShell execution policy is default set to Restricted.

PS G:\> get-executionpolicy -List

  Scope                    ExecutionPolicy
  ---------------       ----------------
  MachinePolicy       Undefined
 UserPolicy              Undefined
 Process                   Undefined
 CurrentUser            Undefined
 LocalMachine         Undefined
 
 List of four different execution policies in PowerShell

  Restricted – No scripts can be run.
  AllSigned – Only scripts signed by a trusted publisher can be run.
  RemoteSigned – Downloaded scripts must be signed by a trusted publisher.
  Unrestricted – All Windows PowerShell scripts can be run.

Workaround solution is, you can change the PowerShell execution policies with Set-ExecutionPolicy cmdlet. Run PowerShell as administrator, Give it the remote signed execution policy which allows to execute that script

PS G:\> powershell -ExecutionPolicy RemoteSigned
- it will take time to set the policy

OR

PS G:\> Set-ExecutionPolicy RemoteSigned

MSCRMMonitoringTest Logging 'Monitoring test failed: Test Title: Help Content Server Tests.: Machine: DNSSES1234: ServerRole: HelpServer'

MSCRMMonitoringTest Logging 'Monitoring test failed: Test Title: Help Content Server Tests.: Machine: DNSSES1234: ServerRole: HelpServer'

Every 15 minutes, CRM Logging the below error

Event 18732, MSCRMMonitoringTest

Monitoring test failed: Test Title: Help Content Server Tests.: Machine: <Server_Name>: ServerRole: HelpServer
Test Log:
The remote server returned an error: (404) Not Found.
   at System.Net.HttpWebRequest.GetResponse()
   at Microsoft.Crm.Monitoring.WebHelpers.GetWebResponse(String webpage, Boolean setCrmAuth, Boolean useProxy, Byte[] postData, Boolean setUserAgent, Int64 dmzPort)

   at Microsoft.Crm.Monitoring.Engine.MonitoringRuntime.ExecuteMonitoringTest(MonitoringTestBase test, Int32 attempts)

InnerException Type:System.Net.WebException
.

Workaround solution to fix the above logging error

1. Create TestsToExclude.xml file,
<MonitoringTestsToExclude>
    <Test isDisabled="true">VerifyHelpContent</Test>
</MonitoringTestsToExclude>
2. Place it on %ProgramFiles%\Microsoft Dynamics CRM\Monitoring folder (all Servers).

3. After 15 minutes, you see the log with succeded message

All monitoring tests succeeded: Machine: APWMAD0A2398: ServerRole: HelpServer.

MSCRMMonitoringTest Logging 'A certificate registered for use by Microsoft Dynamics CRM has expired'

Every 15 minutes, CRM Logging the below errors

I found 2 expired (invalid) certificates on the servers (Deployment & all UI Servers).

Workaround solution to fix the above logging error

1. Delete older one (yellow color tag) certificate from all servers
A) Run cmd -> type mmc -> Console Root window -> File menu -> select Add/Remove Snap-ins -> Add Cerificate -> Select(Computer account) -> Finish -> OK.

B) Console Root -> Certificates (Local Computer) -> Personal -> Certificates
   -> Select old cerificate (date ended with '02/15/2017' ) -> Delete.

2. Re run ‘Configure Claims-Based Authentication’ tool from CRM Deployment Manager.

3. After 15 minutes, you see the log with succeded message
Monitoring test succeeded: Test Title: Trusted Issuer Certificate test: Machine: <MACHINE_NAME>: ServerRole: DiscoveryService, Portal, ApiServer
