RDP error “The function requested is not supported”

8 Jun

I had the same issue. I found the issue has to do with a Windows Update patch that was pushed out to my work station in last nights Windows Updates. There was a critical CVE (CVE-2018-0886) for RDP which required a patch to fix.

If you workstation is patched, but your server isn’t, your workstation will fail to connect.

Quoting from the following blog website with information about the issue, you’ve got three options:

  • Patch your target computer for CVE-2018-0886 (Recommended)
  • Enforce the Vulnerable parameter on the source computer (Not recommended)
  • Disable NLA on your target computer (Not recommended)

I didn’t have alternative access to the server(remote access only), so I had to chose Option 2 so I could go do the updates on the server.

I opened the start menu on my work station, searched for “group policy”, clicked Edit Group Policy. Then following Microsoft spec, Go to “Computer Configuration -> Administrative Templates -> System -> Credentials Delegation”, then :

  • Setting Encryption Oracle Remedation set to “Enabled”
  • In Options below, set “Protection Level: to Vulnerable

Lets Encrypt – Freehostia Website Hosting

5 Jun

You can request the free SSL in the My Domains -> Hosted Domains section of your account. Click on Edit Domain and update the Shared IP to a Shared IP for SSL and then the SSL Certificate field will automatically update to Request Let`s Encrypt SSL.

Finally just click on Edit Domain and the request will be processed.

Note that the domain you are requesting the Let`s Encrypt SSL must be using our NS records, because the SSL validation procedure is DNS based, so the domain should be pointed to your account.

It takes about 30 minutes for the SSL to be issued and installed.

Once your website is reachable with https you can force a https redirection. To check if the SSL is operational clear your browser`s cache and try loading your website with https – https://your-best-domain.com/.

If you wish to force a https redirection you need to do it with a command in the .htaccess file, located in the main domain directory.

The redirection command should be placed in the beginning of the .htaccess file:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Outlook 2016

22 Feb

Issue: Outlook 2016 (which I am testing) cannot connect to Office 365 Exchange.

It is no longer possible to manually enter Exchange Server details. A valid Autodiscovery record is required. Use this site to find out which autodiscovery mechanism you are using.

Verifies that we do have a valid autodiscovery record and that we use the HTTP Redirect method. It also shows that Outlook tries several other autodiscovery methods before the correct (for my organisation) HTTP redirect method.

Solution

What is actually happening is that Outlook 2016 on the PC is hanging when performing the HTTPsAutoDiscoverDomain method. We can force it to use the correct method by the following registry entries.

If Outlook is slow finding the autodiscover records, you may need to tell Outlook to exclude the root domain or other records.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\AutoDiscover\
DWORD: ExcludeHttpsRootDomain
Value: 1

The other records you can exclude, also under the Autodiscover key are as follows. Use a value of 1 to enable, delete the key if you no longer want to exclude these checks.

DWORD: ExcludeScpLookup
DWORD: ExcludeHttpsAutoDiscoverDomain
DWORD: ExcludeHttpRedirect //I DON’T EXCLUDE THIS ONE BECAUSE I USE IT
DWORD: ExcludeSrvRecord
