If you want to create an NLB on Windows 2008 R2 Hyper-V, you will notice that all previous blog posts around this topic will do you no good.. Although you can setup the NLB, network traffic will halt no matter what you do.. change the mac to static, revert it back etc etc.. seems Hyper-V version […]

Query AD for information

So.. been busy lately.. but here’s a new topic.. Windows 2008? R2? Kerberos? No.. it’s scripting..

I had a customer who wanted to extract information from AD by a custom application. Offcourse we could open port 389 and have them extract the info.. but perhaps it would be easier to just query the Global Catalog (if the info you want is in there)..

Group Policy Preferences & Drive Mappings

When using GPP’s to map drives, some of you will notice that some drives are not correctly mapped on the clients.

Poor man's iSCSI

If you want to implement iSCSI it’s best to keep the normal network traffic and the iSCSI traffic apart from each other.

Administrator Lock-out?
