EXCEL Import into OUTLOOK calendar problems

Posted on 2025/03/05 by maoeh
  1. To make it more easy to create an Excel sheet to be imported into Outlook, make first an export of a few entries of Outlook. This will show all the possible options and how they are filled. You can add whatever you like at Excel as the import into Outlook allows you to select the options of Excel to match Outlook .

Here is a sample list:

Problems I had:

Problem: Outlook import greyed NEXT buttom

Import a CSV file ended with a greyed NEXT button. I did not recognize the little button left to the destination that I had to select.

Problem: Outlook import values in line not list

Map Custom Fields shows values to import in one line not a list. The problem was that Excel did not export to a CSV (Comma seperated Value) using comma but the region computer setting. You can see it when you open the CSV using a simple notepad.

To change it run Control Panel > Clock and Region > Change Date …. number format >

Additonal Settings > Numbers> List separater. Change it to comma “,” and apply it.

Now export again the Excel table to a CSV and you can select the values in Outlook. Or, manualy change the separators with an editor to comma before importing it to Outlook.

Then import worked excellent, all my problems where solved.

Set processor affinity for scom agent

Posted on 2019/03/23 by maoeh

Problem

SCOM agent tasks are consuming 100% processor time causing a slow reaction time on servers.

Solution

Force SCOM agent processes to run on one CPU-core so other tasks get processor time.
To achieve this add a scheduled task running the following script every 5 minutes to force processes to run on one core . Here on core 2.
You have to run this job frequently as SCOM is starting new processes every now and then.

This is a simple way to reduce load after max 5 Minutes

$processes = get-process
foreach ($process in $processes)
{
$procid = $process.ID
If ($process.ProcessName -eq "HealthService")
{
$ScomProc = Get-Process -id $procid; $ScomProc.ProcessorAffinity=2
}
If ($process.ProcessName -eq "MonitoringHost")
{
$ScomProc = Get-Process -id $procid; $ScomProc.ProcessorAffinity=2
}
}

Revoke certificate from Microsoft PKI

Posted on 2019/02/10 by maoeh

This solution is based on powershell module PSPKI . Here is a link to download it : https://www.powershellgallery.com/packages/PSPKI/3.2.7.0

Open Poweshell and run the following commands

Import-Module PSPKI
$sCAServer = "<FQDN of your CA Server"
# read certificates into a variable . This needs time
$issued = get-ca $sCAServer | get-issuedrequest
# find the certificate you like to revoke. Adjust the query so the result shows only certificates to remive
$issued | where {$_.commonname -like "Computername1"} 
# Finally run the query with Revoke command
$issued | where {$_.commonname -like "Computername1"} | Revoke-Certificate -Reason CeaseOfOperation

Here an other way using a list of certificate id’s

Import-Module PSPKI
$sCAServer = "<FQDN of your CA Server"
# read certificates into a variable . This needs time
$issued = get-ca $sCAServer | get-issuedrequest -Property CertificateTemplate,UPN,Request.CommonName 
$certids = "2766,16536,16537,16538,2848,2925"
 
foreach ($certid in $certids.split(","))
{
            write-host $certid
            # $certs  | where {$_.RequestID -like $CertId } | Revoke-Certificate -Reason "hold"
            $certs | where {$_.RequestID -like $CertId } | Revoke-Certificate -Reason "CeaseOfOperation"
}

Enable access to a file system share using dns alias

Posted on 2019/01/11 by maoeh

Out of the box Windows is not allowing access to a file system share exept using the server name. Example  \\Server\share or \\server.domain.com\share

To access a share using a dns alias do the  following.

  • create a dns alias pointing to the server
  • change the following regkeys on the server

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
“DisableStrictNameChecking”=dword:00000001

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
“SrvAllowedServerNames”=hex(7)
Add all names in fqdn format to this multistring  including the server:
example: server.domain.com alias1.dmain.com alias2.dmain.com

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
“OptionalNames”=hex(7):
Add  all names in short Netbios format to this multistring without the server name:
example: alias1 alias2
Info: Accessing a share using short names will result in password errors without this parameter.
example: dir \\server\share

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
“BackConnectionHostNames”=hex(7)
Add  all names in fqdn format to this multistring including the server:
example: server.domain.com alias1.dmain.com alias2.dmain.com

  • Restart the server (optional on a non productive server restart the service lanmanserver)

Switch to the failover or new system

  • apply all the settings above on your failover server
  • Lower DNS TTL settings of all DNS entries used as alias so a DNS change happens faster.
  •  
  • Change all dns aliases to your new server
  • Remove alias SPN on your old Server object in ADDS.
  • Add SPNs on your failover server object in ADDS
  • remove the settings above from your old server.
