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:
Refresh the page.
Go back to the previous page.
Exchange 500 Error: Fix
Firstly (let’s check the basics,) make sure all the services are up and running, (this can take a while).
Start All Exchange Services
[box]
Get-Service *Exchange* | Start-Service
[/box]
I can see that my ECP virtual directory is setup correctly
So the most common advice out there is to removeethe virtual directories, and recreate them, but when I attempt to remove them I get the error;
The operation couldn’t be performed because object ‘EX-SERVER-NAME\owa <Default Web Site>’ couldn’t be found on
‘DC-NAME.pnl.com’.
There are some posts that suggest (I simply re-sync my Exchange to my Domain Controller). But I’m not really sure how thats possible, (without a reinstall?). If someone would like to post below an alternative solution I’d be happy to publish it?
This is how I end up fixing it every time, which impractical because it involves downtime! Download the latest Cumulative update, mount the the CD image, and run;
YES I ACCEPT: That’s like using a sack of sledgehammers to crack a nut, but it works. As I’ve pointed out above, I’m happy to publish a more elegant solution, if someone posts one below.

While attempting to connect to a FortiGate firewall (with Firefox over HTTPS) you may see this error;
Secure Connection Failed
An error occurred during a connection to {x.x.x.x} SSL received a record that exceeded the maximum permissible length error code : SSL_ERROR_RX_RECORD_TOO_LONG
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem
Solution: SSL_ERROR_RX_RECORD_TOO_LONG
My colleague went all round the houses trying to fix this, then asked If I knew what was wrong, annoyingly one Google search gave me the answer;
You can only manage the FortiGate via HTTP when using an evaluation licence!

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 (mac OSX)
Try to execute the jnlp file again, but under ‘Open with” Select Other.
Select your hard drive, then System > Library > CoreServices > JavaLauncher.app > (Tick Do this automatically for files like this from now on.) > Open.
Now the file will get blocked by security (if you’ve done anything technical on a Mac you should know how to get round that) Click the Apple Icon (at the top of your screen) > Preferences > Security and Privacy > General Tab > Open Anyway.
You might get some further Java warnings but you should now be able to run the application.

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 product called Active Sync was involved?
Anyway I got a request from a client this week to have Microsoft Edge on their Citrix environment, there was some confusion (imagine that), because Edge does not work on server 2016, (and it’s not shipped as part of server 2016), but would Microsoft Edge work?
Installing Microsoft Edge on Server 2019/2016 (With IE11)
Why is Internet explorer still alive? Anyway If you want to install Edge on a modern Windows server firstly ensure you are fully up to date with updates! Then open IE. Internet Options > Security > Custom > Scripting > Enable Active Scripting > OK > Yes > Apply > OK.
The first test was, ‘would it run on Server 2016’, it detected the OS as Windows 10 (unsurprisingly), and installed fine;
Microsoft Edge on Remote Desktop Services
Well Citrix is really just Remote Desktop Services in a leather jacket, so the next test was,’ would it work in RDS?’ I span up an RDS farm on the bench, and was pleased to see I could select Microsoft Edge as a RemoteApp, (not that I needed to deploy it using RemoteApp, but it being detected was promising).
And in an RDS session it worked faultlessly.
Deploy Microsoft Edge on Citrix (Server 2016)
Here’s where we had a problem, it installed fine, but every time I went to open it, all I got was a ‘white screen’ for about 5 minutes, after this it burst into life, which I couldn’t really ask the client to put up with!
As this was happening when I launched the browser I ‘wrongly’ assumed it was a ‘first run‘ problem (for the uninitiated, previous Microsoft browsers got an annoying ‘how do you want to set the browser up’ routine, then finally dumped you on the MSN webpage, (does anyone actually use the MSN webpage?) While it didn’t cure my problem it’s worth mentioning how I stopped the first run dialog happening);
Controlling Microsoft Edge with Group Policies
If you are used to importing ADMX and ADML files then this will be a breeze to you. If you are really interested I cover the subject in great deal in the following post;
Computer configuration > Policies > Administrative Templates > Microsoft Edge
[/box]
Microsoft Edge: Stop Importing of Bookmarks/Favourites
Locate: ‘Automatically import another browser’s data and settings at first run‘ > Enable the policy, and select ‘Disable automatic import and the import section of the first run experience is skipped‘ > Apply > OK.
Microsoft Edge: First Run
This will disable the entire first run dialog;
Locate: ‘Hide the First-run experience and splash screen‘ > Enable the policy > Apply > OK.
As it was working in RDS and not working on Citrix, then the problem was probably Citrix*. Citrix is one of my weaker subjects, so credit for the actual fix should go to my colleague (Dan Brookes).
*After I had discounted existing group policies, and other installed applications.
Running Microsoft Edge while it was ‘hanging’ and looking at what was going on in ‘Process Monitor’ showed a lot of hook64.dll entries;
This pointed to the culprit, open the registry Editor (regedit) and navigate to;
[box]
HKEY_LOCAL_MACHINE > System > CurrentControlSet > Services > CtxUvi
[/box]
Locate the UviProcesExcludes REG_SZ value, edit it and add ‘msedge.exe;‘ to the end.
Theres probably one service you can restart, but I simply rebooted the server, (problem solved).
FSLogix and Microsoft Edge
If you are running FSLogix you should also add an ‘exclusion’ to the Redirections.xml file, (located in your \\{domain-name}\NETLOGON folder).
