I had a strange issue everywhere in the server if I try to right clic and properties, nothing appear. In IIS, local users and groups ….

To fix it : open a prompt :

regsvr32 %systemroot%system32ole32.dll

Works.

After a clean install of Windows 8 I was not able to have sound from external speakers connected to a docking station.

Install drivers from HP, reboot.

From the HP website I downloaded the drivers IDT Sound drivers but the installation return : Not a compatible Hardware.

2 options.

Option 1 :
In device management / Sound Video and Game Controller I deleted the High Definition Audio
Inject a driver from softpedia,
http://drivers.softpedia.com/progDownload/IDT-High-Definition-Audio-Driver-61064290-for-Windows-8-x64-Download-188054.html

Option 2:
In device management / Sound Video and Game Controller I deleted the High Definition Audio and try the installation of HP.

All is good.

Hi,

To Regenerate the Self Signed Certificate for Exchange this might be a bit tricky.

Open the Exchange Power Shell.

For SBS Server the names of the certificates it’s sites, you need to get the certificate name to be able to regenerate.

Get-ExchangeCertificate -domain “Sites” | fl

Note the ThumbPrint Value.

Generate the New Certificates

Get-ExchangeCertificate -thumbprint “D1B3829EC891FD53C1F87FF8359FFBEE8E3FB412” | New-ExchangeCertificate

Answer A to All

Enable Exchange Certificate for all the services

Enable-ExchangeCertificate -thumbprint “D1B3829EC891FD53C1F87FF8359FFBEE8E3FB412” -services IIS

After the certificate renew, you might receive on the server and the workstation

“This Ca Root Certificate Is Not Trusted. To enable Trust, Install This Certificate In The Trusted Root Certification Authorities Store”

Go to the Default Web Site in IIS and remove the Self Signed Cert **** The old one **** Check the certificate Date. Right click the Default Web Site, Directory Security, Server Certificate, Next, and Remove the cert.

Open Certificates in MMC. Go to Run, MMC. File Add Remove Snap In, Add Certificates; Computer Account; Local Computer and Click OK.

Copy the new cert to the Trusted Root Certification Authorities Certificates.

Go back to the Default Website in IIS, Properties, Diretory Security, Server Certificate. Assign an existing certificate and choose the new cert that was created.

Open a prompt : IISRESET

Adding users to sudoers

We will be editing /etc/sudoers file for this:
sudo gedit /etc/sudoers

Look for the following line:
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

Add a lines as explained below:

If you have set default domain
username ALL=(ALL) ALL # Allow specific account to sudo
domain^admins ALL=(ALL) # Allow admin group
domain^users ALL=(ALL) ALL # Allow all domain users

if you are not using default domain then you have to include the domain name:
%mydomain\yourusername ALL=(ALL) ALL
%mydomain\domain^admins ALL=(ALL) ALL
%mydomain\domain^users ALL=(ALL) ALL

Add domain username to login screen user list

sudo gedit /etc/gdm/custom.conf
Add the greeter part at the end of the file. Add your domain username to include section and any other you want to exclude.

[greeter]
Include=domainusername,domainusername2
Exclude=administrator,guest,nobody
