While working with server builds and configurations, one is frequently faced with a scenario where the system (as a client), needs to connect to a server at the other end and the process doesn't work. If one's lucky then an intelligent message is returned by the interface, hinting about the problem but more often than not, the [...]
Configuration of VRM Server (vSphere Replication Management Server) is one of the steps that one has to perform while installing SRM (Site Recovery Manager) 5.0. A prerequisite for it is to have a compatible database available and the VRMS appliance deployed in advance. However, when going through the configuration, one could sometimes see an error message while [...]
When upgrading a vCenter server from version 4.x to 5.0, you may encounter an error: "The Windows installer service could not be accessed. This can occur if you are running windows in safe mode, or if windows installer is not correctly installed. Contact your support personnel for assistance." You may genuinely have a broken Windows [...]
When sharing a printer on a Windows 2008 R2 machine (or on Windows 7 for that matter), the operation might fail with the following error message: Printer settings could not be saved. Operation could not be completed (error 0x000006d9) This could happen if the Windows Firewall service on the computer is stopped or disabled. Enabling [...]

As I've been asked about this several times, I thought I should post something about it as this doesn't seem to be common knowledge: VMware Tools can be installed on Windows 2008 (R2) Server Core. A common misconception is that since Server Core doesn't have a GUI (Graphical User Interface), it can't run the VMware [...]
We're using ADMT (Active Directory Migration Tool 3.2) these days as part of a restructuring exercise from a multi-domain forest to many single-domain forests. That requires migration of users, groups but also computers from one forest to another (verified two-way external trusts are in place). One issue we saw while migrating computers was that migration [...]
I know - you must be thinking why would anyone want to upgrade a vSphere 4.0 environment to 4.1 when version 5.0 is out now. Well, I can think of a couple of reasons why one might think of doing that. One is the fact that many organisations are still not ready to move to version [...]
Our organisation is going through a major restructuring phase these days and we’re converting from an “Empty Root with many Child Domains” to “Single Domain Forests” model.
