Windows Server – Fails Installing .Net 3.5
KB ID 0000924 Problem I needed to add .Net 3.5 to a Windows Server for an application install, but when I added it as a ‘feature’ it failed. Server 2016 The request to add or remove features on the specified server failed. The source files could not be found. Use the “Source” option to specify the location of the files that are required to restore the feature. For more information on specifying a source...
An Invalid Directory Pathname Was Passed
KB ID 0001338 Problem While attempting to delegate administration of an OU, I got this error; Delegation of Control Wizard The wizard cannot retrieve security information from the Active Directory. An invalid directory pathname was passed. Solution Took a while to figure out! The OU in question has a ‘slash’ in the name of it; Once I changed this to a hyphen, the error ceased.

Using LDP to Find an Objects ‘Distinguished Name’ in Active Directory
KB ID 0001337 Problem There are a few occasions when you need to know an objects ‘Distinguished Name’ (DN). For me it’s usually when I’ve got a device that needs to do LDAP/LDAPS lookups, (RSA Appliance, Netscaler, Cisco FirePOWER, etc). Today someone needed to ‘bind’ a Checkpoint firewall to Active Directory, and asked me to create user, and give them the DN and password. I’ve mentioned...
Windows – Unable to Move an OU
KB ID 0001336 Problem I was doing some AD redesign work for a client this week, and I needed to move an Organisational Unit (OU). However the domain had other ideas; Active Directory Domain Services Windows cannot move object {OU-Name} because: Access is denied. It wasn’t a rights issue, (I was an Enterprise Administrator). Solution As it turns out, it was the same problem I’d had back when Server 2008 first came out...
Windows Folder Redirection
KB ID 0000467 Problem Q: What is Folder Redirection? A: Essentially you can take folders that hold things like your “My documents” or your “Favorites” folder, and put them out on a network server, which is great if you want to back that sort of information up for disaster recovery. Q: What’s the difference between this and a roaming / roving profile? A: Folder redirection keeps information on a server...
Microsoft PKI Planning and Deploying Certificate Services Part 3
KB ID 0001312 Problem Following on from Part Two, now we have an offline Root CA, and a CRL server, our next step is defined by our PKI design, are we three tier, or two tier? (Look in Part One for a definition). Solution As previously mentioned, Microsoft just treats Intermediate CAs and Issuing CA’s as the same thing (SubCAs). So the next step is identical for either. But I would suggest one difference, If I was deploying an...
WannaCry – Protect Yourself
KB ID 0001311 Problem Last Friday, the IT world was hit by another attack, WannaCry is a Ransomware infection, that exploits a hole in the windows SMB Protocol. This hole was patched back in March, (Security update MS17-010) so if your, (windows update supported systems) have updates enabled, you will probably already be protected. Why were big organisations like the NHS hit? Primarily because they have systems that are no longer...
Microsoft PKI Planning and Deploying Certificate Services Part 2
KB ID 0001310 Problem In Part One we deployed our offline Root CA Server, now we are going to deploy a ‘Certificate Revocation Location’ server. Solution Before you start: Create a DNS record for ‘pki’ that points to the IP address, that you will have the CRL web server hosted on. I’m installing my CRL server on a separate web server because thats good practice. Starting with a domain joined member...
ADMT (Active Directory Migration Tool) Domain Migration – Part 4
KB ID 0001308 Problem On the homeward stretch now, back in Part Three, we migrated service accounts, groups, and users. Now we turn our attention to our machines. Note ADMT 3.2 Only support the migration of Operating Systems up to Windows 7, (that doesn’t mean Windows 8 and Windows 10 wont work, it just means they are not supported). Migrating Windows 8 and 10 throws a lot of security translation errors, because of the way it...
Microsoft PKI Planning and Deploying Certificate Services
KB ID 0001309 Problem “I don’t know what it is about Certificates, I just don’t like them, I don’t understand them, and I don’t like working with them” I hear this a lot, In fact I heard it this week, and as I’m usually the ‘go-to-guy’ for certificates and PKI, it winds me up! IT pros take the time to learn concepts like DNS, DHCP, Kerberos etc. But mention Certificate Services and...
