Cant Copy a Group Policy Object
KB ID 0001543 Problem Was asked this this morning, why couldn’t someone ‘Copy’ a Group Policy Object (GPO)? Solution At first I was confused, (I made the same mistake they had), look at what I’m trying to copy? It’s not a Group Policy Object, its a ‘Link’ to a GPO. (Note: There’s a shortcut arrow!’) Locate the actual GPO and you can copy it! Related Articles, References, Credits,...
Test Port Connectivity Through a Firewall
KB ID 0001541 Problem Test Port Connectivity: I was asked if I had a test Exchange server that someone could test TCP port 587 to this morning. Usually if I need to test a port I simply use Microsoft IIS and then set it to the appropriate port, add a ‘welcome banner’ and telnet to it. This time it didn’t work, so I found a small application that you can use for this very purpose. How to Test Port Connectivity Test...
Veeam: Error No Backup Proxy is Available
KB ID 0001540 Problem I was asked to take a look at this by a colleague; Unable to allocate processing resources Error: No backup proxy is able to process this VM due to proxy processing mode restrictions. Solution This is a pretty generic error to be honest, at first glance it would look like the proxy either needed more CPU/RAM, (or another proxy adding altogether). However and the root cause was the Veeam server was attached to...
Remote Connect to macOS
KB ID 0001539 Problem Remotely connecting to Windows is easy we’ve had RDP since Windows NT4, (yes I’m that old). But what if you want to remote connect to a mac? Well that has ‘Screen Sharing’ built in, (which it pretty much the same, but it uses VNC). If you’re unfamiliar with VNC, (Virtual Network Computing,) you can install it on both Windows and Linux. Normally you need a client, (to connect with)...
Windows Adding Firewall Rules With PowerShell
KB ID 0001538 Problem There was a question on Experts Exchange this morning, the asker wanted to be able to add a ‘Trusted’ network range to their Windows Server Firewall settings as a ‘allow all ports’ rule. Solution You can of course add this manually in the GUI, normally I’d simply Add a Firewall Rule with a Group Policy. but the problem with that is, that’s fine if you want to open a particular...
Safari – Download ZIP files (Not Open Them!)
KB ID 0001537 Problem I’d forgotten Safari did this, after replacing my mac a few weeks ago I was trying to download a ZIP file from Github, and was perplexed that it was getting extracted to a folder in my downloads folder, and not appearing as a ZIP file? Solution After about the third time, the penny dropped. Safari does this by default. You need to disable it. Safari > Preferences > General > UNTICK : Open...
You Have Exceeded the Maximum Number of Computer Accounts
KB ID 0001536 Problem A few weeks ago, this was asked in a forum, and while I knew what the problem was, I’d never seen it myself. So I recreated the problem on the test network to look at why it happened, and how to fix / get around the problem. The following error occurred attempting to join the domain {domain-name} You computer could not be joined to the domain, You have exceeded the maximum number of computer accounts you...

Review the log file at %WINDIR%\System32\Sysprep\Panther\setupact.log for details. After resolving the issue, use Sysprep to validate yout Installation again.

VMware: Fiber Channel HBA Reports Wrong WWN?
KB ID 0001534 Problem I was building some new ESX 6.7 U1 (HPE) servers this week, they had Emulex Fiber HBA’s in them. When it came to ‘allowing’ them access to the SAN, I went to get the Port World Wide Name; And was presented with this; Not only is that 19 Characters long, and not 16 characters, but BOTH VMHBA’s WERE THE SAME! Like MAC addresses they should be unique? So I’m guessing this is a bug....
Cisco IOS: Ether-Channel Trunks
KB ID 0001533 Problem This is a subject that every time I need to create an Ether-Channel I end up checking beforehand, so it’s about time I wrote it up. We are combining two different things, an Ether-channel, (an aggregation of links) and a Trunk (the ability to carry many VLANS). If you are NOT from a Cisco background then you might want to read though the following post first to avoid confusion about the world...
