How To Remove A Printer From Active Directory

$
0
0

If your deleted shared printer is still listed in Active Directory, you can remove the deleted printer by:

  1. Opening Active Directory Users and Computers
  2. Search the root of your directory, but change the drop down from Users and Computers to Printers
  3. Find the printer and right click and deleted it

It’s kind of annoying that when you rebuild a print server, the old printers listed in the directory don’t match the new printers on the server – obviously this is because the printers listed were associated with a computer with a different SID (a different install of Windows). The only solution is to delete the listed printers and share the new ones out.

The Skype can’t connect error is a terrible error, but easy to fix.
According to Skype support, Skype can’t connect occurs if you need to upgrade Skype.

This is a terrible error. I don’t know why Skype didn’t just display a message saying “You need to upgrade Skype”.

However, as I mentioned earlier, it’s an easy fix:

To fix the Skype can’t connect error, just upgrade Skype to the latest version.

Your IMAP server wants to alert you to the following: Please log in via your web

When using GSuite GMail with Microsoft Outlook, you get this alert:

Your IMAP server wants to alert you to the following: Please log in via your web browser:
https://support.google.com/mail/accounts/answer/78754 (Failure)

If you get the Please log in via your web browser error, then welcome to GSuite hell.

The best I can suggest is to try each of the options on the following article: https://support.google.com/mail/accounts/answer/78754

I never managed to fix this problem, myself. I’m not sure why it worked for several days before having this issue. ❗ I’ve since managed to fix the Please log in via your web browser error here:

This Setting Is Managed By Your Domain Administrator – Less Secure Apps

I’m left wondering if this is going to happen again, and glad I’m not rolling GSuite out to a large organisation!

This Setting Is Managed By Your Domain Administrator – Less Secure Apps

An annoying feature of Gmail (GSuite) is that after a while it will stop you from logging into your email via Outlook (or other client app), and when you go to turn on access via Less Secure Apps, it will tell you that:

This setting is managed by your Domain Administrator.

For me, was working fine with Less Secure Apps turn off, then it stopped working after a few days (just when the free support ran out). Then it actually allowed me to turn on access from Less Secure Apps, but still didn’t work. A few days later, I then went back to the same setting, which was greyed out and I couldn’t enable access from Less Secure Apps. I was logging on as the Domain Administrator the whole time, but was told that I couldn’t change the setting because it’s managed by my Domain Administrator. Genius! 🙁

I fixed this, by logging onto the Admin Console (as the same Domain Administrator account as before!), then navigating to the setting to enable Less Secure Apps for everyone. After about 2 minutes, I was then able to use my Outlook client.

InstallScript Setup Launcher Unicode Has Stopped Working

When trying to install the OfficeScan Agent, you get this error:

InstallScript Setup Launcher Unicode has stopped working

A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.

To fix this, right click the AutoPcc.exe setup and use the Compatibility Troubleshooter. I found that it worked in XP mode, but it depended on which OS you were running it from.

Some computers didn’t work with compatibility mode (others with the InstallScript Setup Launcher Unicode has stopped working error did). I found that since the InstallScript Setup Launcher error occurred while doing the prescan, turning prescan off seemed to work.

Unable To Install The OfficeScan Agent. There Was An Error Copying VSAPI32.DLL

$

When trying to install the OfficeScan Agent, you get this error:

Unable to install the OfficeScan Agent. There was an error copying VSAPI32.DLL. Please contact your OfficeScan Agent administrator for assistance.

This is an unhelpful error message because the problem isn’t actually an error copying VSAPI32.DLL, it’s an error copying the OTHER installation files for OfficeScan.

To fix this error, find all the files that have been renamed to xxx_invalid in the PCCSRV (C:\Program Files (x86)\Trend Micro\OfficeScan\PCCSRV) directory on the OfficeScan server to remove the _invalid part of the filename.

To help you fix the error copying VSAPI32.DLL, here’s a PowerShell script (sourced from Trend Micro themselves):

cd “C:\Program Files (x86)\Trend Micro\OfficeScan\PCCSRV”
Get-ChildItem -Recurse -Include *_invalid | Rename-Item -NewName { $_.name -replace “_invalid”,”” }

❗ Note: You have to run the PowerShell cmdlet as Administrator.
❗ Note: Don’t forget to change the directory in the first line to the location of your PCCSRV directory on the OfficeScan server hosting the installation files.

Here’s more information on Trend Micro’s _invalid files.

Why Do Trend Micro Files Get Renamed To _Invalid?

$

There are a copy of reasons why Trend Micro’s OfficeScan Agent’s installation files get _invalid appended onto them:

  • If you do not shut down the Trend Micro service properly
  • If you are updating Trend Micro and run out of disk space
  • If you get part way through the Trend Micro install or update and it fails

According to Trend Micro, you can simply remove the _invalid part of the file name; Trend Micro even provide a handy Powershell script to do this for you:

cd “C:\Program Files (x86)\Trend Micro\OfficeScan\PCCSRV”
Get-ChildItem -Recurse -Include *_invalid | Rename-Item -NewName { $_.name -replace “_invalid”,”” }

❗ Note: You have to run the PowerShell cmdlet as Administrator.

CHAR(n) Vs VARCHAR(N) Vs Text In Postgres

$

Before I get into what is the difference between CHAR(n), VARCHAR(n) and Text data types in PostgreSQL, I’ll give you the short answer to what you want to know:

If you want to store some text with an unknown length, use the Text data type.
If you want to store some text with an unknown length, but you know the maximum length, use VARCHAR(n).
If you want to store some text with a known exact length, use CHAR(N).

There are some variations on that, but that will fit most scenarios.

Basically, VARCHAR(n) stores the text in the database as is, CHAR(n) pads the data out with blank space so it’s as long as the maximum size. Both are exactly as performant as each other, but some queries might take longer if you’re doing a text comparison (because you’re comparing more data in the padded CHAR(n) data).

I won’t go into how the Text data type works, but basically it has no maximum size and overflows the excess data into a Toast table in Postgres. So use VARCHAR(n) or CHAR(n) if you can.

HP Storage Discovery Service High CPU

The HP Storage Discovery Service seems to be using a large percentage of the CPU. I noticed that a backup was running on the server. I don’t know what the HP Storage Discovery Service does, but when I stopped the HP Storage Discovery Service it seemed to fix my high CPU problem.

I’ll report back if I get any issues from stopping the HP Storage Discovery Service.

DataGridView Cannot Clear This List

Sometimes you get “Cannot clear this list” when trying to clear a DataGridView using the Clear() method. If you get Cannot clear this list, that’s typically because the DataGridView is connected to a datasource. Try clearing the datasource instead, or disconnect the datasource from the DataGridView.

Use the following SQL query to show a list of linked tables in Microsoft Access:

SELECT MSysObjects.Name, MSysObjects.ForeignName, MSysObjects.Database
FROM MSysObjects
WHERE ((Not (MSysObjects.ForeignName) Is Null));

This query shows the linked tables in Microsoft Access, along with the location of the dated linked to.


Unable To Change Security Permissions On Printer – Greyed Out

$

This is a really dumb setting: If you are logged on as an Administrator, by default you will be unable to change the security permissions on a printer. It will be greyed out because you need to go to the General tab on the printer, then click the Change Properties button at the bottom. The security tab’s permissions will then no longer by greyed out and you’ll be able to change the security permissions.

A Better Google Site Search In HTML / Javascript

Here’s a nice javascript / HTML based Google Search box that you can put on your website. It’s much better than Google’s site search box because it uses the full power of Google to search, instead of the cut down rubbish search that comes with Google’s search box that’s full of adverts and doesn’t return very good results.

<script type="text/javascript">
function google()
{
var str=document.getElementById('googlebox').value;
str="http://www.google.com/search?hl=en&source=hp&q=site:itsupportforum.net " + str + "&aq=f&oq=&aqi=";
var replaced=str.replace(" ","+");
window.open(replaced)
}
</script>
<input id="googlebox" type="text" value="Google" />
<input type="button" value="Go" />

PCI\VEN_8086&DEV_15B8&SUBSYS_E0001458&REV_00 Ethernet Controller

Ethernet Controller with hardware ID PCI\VEN_8086&DEV_15B8&SUBSYS_E0001458&REV_00 is an Intel(R) Ethernet Connection (2) I219-V. I have tried all the drivers for the Intel(R) Ethernet Connection (2) I219-V that are available on the Intel website, including those for Windows 8, Windows 10 and the Intel OS independent Intel driver pack that (supposedly) contains all Intel drivers for all operating systems (about half a GB of drivers).

None of the above worked. I since found out from an Intel representative that Windows 2012 and Windows 2016 do not support the Intel(R) Ethernet Connection (2) I219-V.

Solution: Buy another network card or install another operating system.
