Microsoft Outlook 2016 hangs on the splash screen

When starting outlook the splash screen displays “starting”, but Outlook never starts.

  1. Close Outlook
  2. Start the “Run” command
  3. Type: outlook.exe /safe
  4. You may be prompted for your user credentials.  If so, enter them.
  5. Outlook should start fairly quickly.  It may take a minute or two to sync to the server.
  6. Close Outlook
  7. Start Outlook as you normally would.

Firefox: Your connection is not secure – certificate warning

When trying to access an internal secured url Firefox may warn you that the connection is insecure while IE works just fine.

This is due to the fact that Firefox uses its on certificate store and your company’s root CA is not a part of this.

To fix the issue do the following:

Start Firefox and type: about:config into the address field

Find: security.enterprise_roots.enabled

and set it to true.

You are now fixed.

You can deploy the configuration enterprise wide by doing the following:

  1. In the Firefox installation folder, go to defaults\pref\ folder and create a new file with the following:
  2. /* Allows Firefox reading Windows certificates */
    pref(“security.enterprise_roots.enabled”, true);
  3. Save it with .js extension, e.g. trustwincerts.js and restart Firefox. The entry will appear in about:config for all users.
  4. Push this out with AD or your favorite tool

Software: Dreamweaver sftp connection issue

If Dreamweaver errors on connecting to your SFTP site do the following:
1. Verify your username and password.
2. Test it manually from a putty or filezilla type program to make certain your credentials work.
3. Reenter the data into Dreamweaver’s site management – server section.
4. Try to connect from Dreamweaver – If the error still occurs, you will want to connect several times one after another.  For some reason Dreamweaver throws the error up before trying to make the connection.  I find that trying to upload a file several times in a row will finally force Dreamweaver to actually try to connect.

Wireshark: Extracting SSL certificates 

Here are the steps for extracting an SSL certificate.
1. Make sure the setting "Allow subdissector to reassemble TCP streams" is on in the TCP protocol preferences (This is selected by default)
2. Then go to the packet which contains the SSL handshake message "Certificate"
3. In the packet detail pane, expand the SSL protocol
4. Expand the "Certificate" TLS record
5. Expand the "certificate" handshake protocol
6. Expand the list of certificates. There is now a list of certificate length and certificates (the list could be only 1 certificate). The first certificate is the server certificate, the second it's signing CA, the third the CA that signed the CA, etc.
7. Now rightclick on the certificate that you want to export
8. Choose "Export selected packet bytes..."
9. Choose a filename and click on save
You can save it as certname.crt on windows and then open it up to look at it.

Citrix: Installing Citrix Receiver 13 on Ubuntu 14.04 (x64)

This was taken from a 13.04 install guide.  If you run into dependency problems when installing it on 14.04
be sure to use “sudo apt-get -f install” to correct any issues.

 

1. Download Citrix Receiver  64bit .deb package from Citrix website. Link

2. Modify the downloaded .deb package as shown in the steps below
dpkg-deb -x icaclient_13.0.0.256735_amd64.deb ica_temp/
dpkg-deb –control icaclient_13.0.0.256735_amd64.deb ica_temp/DEBIAN

3. Now you need to remove the ia32-libs and libasound2 dependencies by editing the control file. I use vim, you can use gedit. Look for the line “Depends: libc6-i386 (>= 2.7-1) ” and change to “Depends: libc6-i386 (>= 2.7-1), lib32z1, nspluginwrapper”
vim ica_temp/DEBIAN/control

4. Once done, repackage the file back to .deb
dpkg -b ica_temp icaclient_13.0.0.256735_amd64-modified.deb

5. Install the dependencies required
sudo apt-get install nspluginviewer nspluginwrapper libXp6:i386

6. Install Citrix Receiver modified .deb package
sudo dpkg -i icaclient_13.0.0.256735_amd64-modified.deb

7. Ignore the nspluginwrapper segmentation fault (if any)
