Can you Use ‘Let’s Encrypt’ on Hybrid Exchange?
KB ID 0001770 Problem A few months ago I wrote an article about getting free exchange certificates with Lets ‘Encrypt’. And that still works peachy, I implemented it on my test Exchange 2019 server (in Hybrid mode) and all appeared well. Some time later, (remember this is my test network so it’s not in production.) I noticed that mail was not getting forwarded from O365 to the on premises Exchange server. I’ve...

Exchange ECP HTTP 500 Error
KB ID 0001756 Problem This infuriatingly happens to me a lot! Every time the fix is the same, (but is a little impractical). Essentially you attempt to log in to ECP (Exchange Admin Center), you a prompted for your credentials, then you just get a ‘500 Error”. The website cannot display the page HTTP 500 Most likely causes: •The website is under maintenance. •The website has a programming error. What you can try: ...

mac OSX: Opening JNLP Files?
KB ID 0001767 Problem I needed to get onto a HPE server’s iLO at work today. I was using Firefox and the .Net extensions no longer work, so I was forced to use Java web start. Annoyingly that opened my Windows 10 VM (that runs in VMware Fusion), then it fell over! So the problem is, I need to be able to ‘RUN’ jnlp file on my MacBook, but there’s no Java application in the applications folder. Opening JNLP Files...
Microsoft Edge on Server 2019/2016 (and Citrix)
KB ID 0001657 Problem In a fit of lunacy Microsoft have called ‘their’ new browser Microsoft Edge, so we can spend the next few months confusing it with Edge. Plus every Google search for GPO settings, error messages etc will all now show search results for the old Edge Browser not the new Microsoft Edge browser! Perhaps the same doofus at Microsoft who called the Exchange sync Active Sync when Microsoft already had a...
Cisco FPR – Re-image from FTD to ASA Code
KB ID 0001766 Problem Note: This procedure is to re-image a Cisco Firepower device from FTD to ASA code, (in this example a Cisco FPR 1010). Why would you want to do this? Well to be frank FTD is bobbins, so if you have a device running FTD code you might want to ‘convert’ it to ASA code. If you tried to do this with an older firewall (ASA 5500-X) then you needed to go to Cisco TAC and try and get them to give you an...
Windows Server – Sysprep
KB ID 0000729 Problem I don’t deploy large amounts of servers at once, so Windows Server sysprep is not as important as it is with the client operating systems I deploy. But I do need to create virtual machine templates, (mostly for testing), but some clients like to have server templates. I prefer to manually sysprep and shutdown a server then either convert or clone it to a template. Thankfully sysprep is in the same place as...

The following is a run through of how to export from a mail store to pst files – Note on a live system this can take...
How To Open KMZ Files
KB ID 0001765 Problem Occasionally I get KMZ files sent to me, (usually from Telcos that are showing me the routes of comms circuits). Basically a KMZ file is a ‘Compressed Map File’. If you need to open KMZ files, then it’s simpler than you think. Open KMZ Files These files can be opened with Google Earth Pro, (it’s a free download and install). There you go.
