Exchange and TLS problems

Today i have a problem that an exchange will not send mails though TLS, no matter what i do.

I find out that, somehow this exchange servers where creating new send connector, with forcehelo = True.

Witch mean that the Exchange server is using the OLD HELO instead of the EHLO, when talking to other SMTP servers. Setting this to false help. Now the Exchange server send with TLS.

So FORCEHELO=$TRUE breaks TLS.

To see if this is the problem, you can type:

get-sendconnector | select id, forcehelo

To set it to false, for the send connector “Default_OUT” you can run this powershell command:

get-sendconnector -id Default_OUT | set-sendconnector -forcehelo $false

Also you might need to set the TLS certificate to the right certificate. Remember that the certificate need to have the hostname in the certificate. Se more on this link:

Enabled RemoteFX locally on a non domain joined computer

For some reason RemoteFX USB Redirection is not enabled standard in Windows.

So what to do with a non domain joined computer, you can change GPO from the Active Directory.

That is not a problem, you can run GPEDIT from the client.

Right click on start, and select Run

And click OK

Now browse to Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Connection Client -> RemoteFX USB Device Redirection

Dobble click on “Allow RDP redirection of other supported RemoteFX USB desvices from this computer”

And change the settings to Enabled, and choice Adminstrators and Users.
Click ok

Now restart you computer, and you should now have enabled RemoteFX.

Change RDWEB to not redirect sound to client

If you have Installed Skype for Business and have enabled RemoteFX.

You might still find that Skype for Business is saying that it using Remote Audio, even if you have redirected you USB headset.

This can be changed, by running this command on in a Administrator Powershell.

Set-RDSessionCollectionConfiguration -CollectionName "YourCollectionName" -CustomRdpProperty "use re
direction server name:i:1 `n usbdevicestoredirect:s:* `n audiocapturemode:i:1 `n audiomode:i:1"

After this go to yours RDWeb page, and download a new RDP fil, and connect with you new RDP file.

After that Skype should say that is using you USB Headset.

Remember to select that you will redirect you USB Headset.

Enable Full Desktop in RemoteApp Collection

If you have a RemoteAPP collection, and you will like to have allow you user, to access a full Desktop.

This can be changed by logging into yours Remote Desktop Broker, and go to the Regedit, and browse to this page:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\CentralPublishedResources\PublishedFarms\<collection>\RemoteDesktops\<collection>

And set the value of ShowInPortal to 1

After this you will have the desktop in RDWeb

RemoteFX not working anymore

Today I have this problem, that no matter what I do. I could get RemoteFX to work.
The strange things is it where working yesterday, and no one will admit that the have changed anything.
And no windows update have been installed.
I was going into debugging, and for some reason I so this registry was set to 0
HKLM -> Software -> Policies -> Microsoft -> Windows NT -> Terminal Services -> fDisableCam


Normally it is not configure on a RDS Session Host server.
So I deleted it, rebooted the server and RemoteFX is now working again.

See if a database is using Enterprise features of an Microsoft SQL server.

Run this command to see if any database on the SQL Server is using enterprise features

IF OBJECT_ID('tempdb.dbo.##enterprise_features') IS NOT NULL
  DROP TABLE ##enterprise_features

CREATE TABLE ##enterprise_features
  (
     dbname       SYSNAME,
     feature_name VARCHAR(100),
     feature_id   INT
  )

EXEC sp_msforeachdb
N' USE [?] 
IF (SELECT COUNT(*) FROM sys.dm_db_persisted_sku_features) >0 
BEGIN 
   INSERT INTO ##enterprise_features 
    SELECT dbname=DB_NAME(),feature_name,feature_id 
    FROM sys.dm_db_persisted_sku_features 
END '
SELECT *
FROM   ##enterprise_features

 

Downgrade an SQL Server from Enterprise to Standard – Disable compression

If you got an error about compression, when trying to attach the database from an enterprise version to a standard version. You will have to attach the database to an enterprise database, and remove the compression first.

The error:

sg 3013, Level 16, State 1, Line 2
RESTORE DATABASE is terminating abnormally.
Msg 909, Level 21, State 1, Line 2
Database 'abc' cannot be started in this edition of SQL Server because part or all of object 'def' is enabled with data compression or vardecimal storage format. Data compression and vardecimal storage format are only supported on SQL Server Enterprise Edition.
Msg 933, Level 21, State 1, Line 2
Database 'abc' cannot be started because some of the database functionality is not available in the current edition of SQL Server.

The SQL Command to run to disabled compression. It should be run on a query on the database with compression.
(Baware of the database will then fill something extra on the storage, so keep in mind that you need to have space available for that.)

SELECT DISTINCT 'ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);'
FROM sys.partitions p
join sys.objects o
on p.object_id = o.object_id
WHERE o.TYPE = 'u'
and data_compression_desc != 'NONE'
UNION
SELECT 'ALTER INDEX ALL ON [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);'
FROM sys.partitions p
join sys.objects o
on p.object_id = o.object_id
WHERE o.TYPE = 'u'
and data_compression_desc != 'NONE'

If the database have compression it will output with multiple SQL commands. Run these command against you database aswell

Example: (You should run what you rnu of the script output)

ALTER INDEX ALL ON [dbo].[MSSBatchHistory] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSChangeLogCookies] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSCrawlDeletedURL] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSCrawlDeletedURLLog] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSCrawlHistoryLocal] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSCrawlReportCrawlErrors] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);
ALTER INDEX ALL ON [dbo].[MSSCrawlURL] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);

Remote Desktop seesions – See sessions on all servers in Active directory

If you have enabled that a user get lock out in Active Directory, if the user type the password wrong X times.
Then you might have experienced, that yours admin account get locked out multiple times, just after you have change the password for the admin account.

It could be that you have left a session on a server in you Active Directory logged on, and that session now trying to authenticated it self, by using you old password.

You can run this script, to check all servers in Active Directory, to see where there are user session on it.

function Get-LoggedOnUsers ($server) {
    if($server -eq $null){
        $server = "localhost"
    }
 
    $users = @()
    # Query using quser, 2>$null to hide "No users exists...", then skip to the next server
    $quser = quser /server:$server 2>$null
    if(!($quser)){
        Continue
    }
 
    #Remove column headers
    $quser = $quser[1..$($quser.Count)]
    foreach($user in $quser){
        $usersObj = [PSCustomObject]@{Server=$null;Username=$null;SessionName=$null;SessionId=$Null;SessionState=$null;LogonTime=$null;IdleTime=$null}
        $quserData = $user -split "\s+"
 
        #We have to splice the array if the session is disconnected (as the SESSIONNAME column quserData[2] is empty)
        if(($user | select-string "Disc") -ne $null){
            #User is disconnected
            $quserData = ($quserData[0..1],"null",$quserData[2..($quserData.Length -1)]) -split "\s+"
        }
 
        # Server
        $usersObj.Server = $server
        # Username
        $usersObj.Username = $quserData[1]
        # SessionName
        $usersObj.SessionName = $quserData[2]
        # SessionID
        $usersObj.SessionID = $quserData[3]
        # SessionState
        $usersObj.SessionState = $quserData[4]
        # IdleTime
        $quserData[5] = $quserData[5] -replace "\+",":" -replace "\.","0:0" -replace "Disc","0:0"
        if($quserData[5] -like "*:*"){
            $usersObj.IdleTime = [timespan]"$($quserData[5])"
        }elseif($quserData[5] -eq "." -or $quserData[5] -eq "none"){
            $usersObj.idleTime = [timespan]"0:0"
        }else{
            $usersObj.IdleTime = [timespan]"0:$($quserData[5])"
        }
        # LogonTime
        $usersObj.LogonTime = (Get-Date "$($quserData[6]) $($quserData[7]) $($quserData[8] )")
 
        $users += $usersObj
    }
    return $users
}

$strCategory = "computer" 
$strOperatingSystem = "Windows*Server*" 
 
$objDomain = New-Object System.DirectoryServices.DirectoryEntry 
 
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher 
$objSearcher.SearchRoot = $objDomain 

$objSearcher.Filter = ("OperatingSystem=$strOperatingSystem") 
 
$colProplist = "name" 

foreach ($i in $colPropList){$objSearcher.PropertiesToLoad.Add($i)} 

$colResults = $objSearcher.FindAll() 

foreach ($objResult in $colResults) 
    { 
    If ($Err -ne $null) {
        Remove-Variable Err
    }
    $objComputer = $objResult.Properties;  
    $ServerName = $objComputer.name
    $isalive = Test-Connection -BufferSize 32 -Count 1 -ComputerName $servername -Quiet
    if($isalive -eq $True) {
        $wmi = Get-WmiObject -class "Win32_Process" -namespace "root\cimv2" -computername $ServerName -EV Err -EA SilentlyContinue
        if ($Err) {
         } Else {
            Get-LoggedOnUsers $ServerName | ft -autosize
        }

    }
}

 

 

You can change this last command:

Get-LoggedOnUsers $ServerName | ft -autosize

to

Get-LoggedOnUsers $ServerName | ? { $_.Username -eq ‘kda’ } | ft -autosize

to only see where KDA is loggedon
