Windows 2008 EventID 513

For a few days now I was getting error with id 513 on my Windows 2008 Domain Controller.

The error had the following details:

Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object.

Details:
AddCoreCsiFiles : BeginFileEnumeration() failed.

System Error:
Access is denied.

I searched for the System VSS writer and it was missing.

In that case you might be having problems with the permissions on the winsxs folder under the windows folder.

You may run the following commands to rough check:
cd /d c:\windows\system32
icacls %windir%\winsxs\filemaps\* > C:\acls.txt

In case the above command fails, you may run the following script in order to restore the necessary permissions:

takeown /f %windir%\winsxs\filemaps /a
icacls %windir%\winsxs\filemaps /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps /grant "BUILTIN\Users:(RX)"
icacls %windir%\winsxs\filemaps /grant "Administratoren:(RX)"
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant "BUILTIN\Users:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "Administrators:(RX)"
Takeown /f %windir%\winsxs\temp\PendingRenames /a
icacls %windir%\winsxs\temp\PendingRenames /grant "Administrators:(RX)"
icacls %windir%\winsxs\temp\PendingRenames /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\temp\PendingRenames /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\temp\PendingRenames /grant "BUILTIN\Users:(RX)"
Takeown /f %windir%\winsxs\temp\PendingRenames\*.* /a
icacls %windir%\winsxs\temp\PendingRenames\*.* /grant "Administrators:(RX)"
icacls %windir%\winsxs\temp\PendingRenames\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\temp\PendingRenames\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\temp\PendingRenames\*.* /grant "BUILTIN\Users:(RX)"

Domain Controller Machine Password Reset

Image
On my lab environment, I've configured two Active Directory sites since most enterprises have offices in more that one places. My lab however is not running 24/7 and the domain controllers in the second site are rarely turned on in order to save resources. This leads to issues with the Active Directory replication such as the "The target principal name is incorrect" error when I execute:  repadmin /syncall /AdeP. To remedy the issue, we have to reset the machine password of the domain controller that has been offline. First off, we are going to stop and disable the Kerberos Key Distribution Center (kdc) service on the problematic domain controller, in our case DC4. There may be some tickets in the cache so we should also clear them using klist purge Now it's time to change the machine password of the domain controller using the command netdom resetpwd /s:dc3 /ud:lab\administrator /pd:* Replace the "lab\administrator" with an account on your...

Managing Active Directory User Certificates using PowerShell

I first came across user certificates when I was working with email certificates a few years ago and I have to admit that I had trouble updating the certificates on the objects! Most organizations have a Microsoft Active Directory Certification Authority that issues the certificates used internally. When a certificate is issued to a user, the Microsoft Certificate Service saves the public key in Active Directory. The userCertificate attribute is a multi-valued attribute that contains the DER-encoded X509v3 certificates issued to the user. Although we rarely need to pay attention to this attribute, there are cases where we have to update it. To make things easier, I've written PowerShell functions to Get, Remove, Import and Export the certificates on that field. To get the list of certificates for an object, use the Get-ActiveDirectoryObjectCertificate function: PS C:\> Get-ActiveDirectoryObjectCertificate -UserPrincipalName cpolydorou@lab.local DistinguishedName  ...

Configuring a Certificate on Exchange Receive Connector

Today's article is about configuring Exchange receive connectors with specific certificates. Out of the box, Exchange uses self signed certificates to provide TLS secured mail flow. This will definitely be an issue if you expose the SMTP protocol to client computers since they won't trust the certificate. In this article we are going to configure a certificate that was issued by a third part authority to the Client Frontend receive connector. We'll start with getting the thumbprint of the certificate using the Get-ExchangeCertificate cmdlet: [PS] C:\> Get-ExchangeCertificate Thumbprint                               Subject ----------                               ------- 241B864DC82C664FECBA18B8D54987AAFB65B4C2 CN=*.lab.com, ...
