Had an interesting one yesterday, my bosses Vista laptop booted as per normal, making all the right pictures until just before the log in prompt popped up, then a black screen in what looked to be VGA graphics with the white default arrow cursor. Corrupted graphics drivers, I thought. A quick boot into safe mode…but no, the same black screen and over-sized pointer. No problem, Last Known Good Configuration will save my day…except that LKGC points are set when the OS manages a successful boot, and Vista had, in it’s own opinion, successfully booted.

I was adding a shiny new domain controller to my server farm earlier today, we have just two Windows 2000 SP4 domain controllers on old kit and they are due to retire. With the hardware selected, purchased and a fresh copy of Windows Server 2003 R2 installed, I set to installing Active Directory. DCPromo.exe fires up and I go through the configuration steps until… "The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003.

If you’ve logged onto the properties for your IIS install and found that the ASP.NET tab has mysteriously disappered, you can try a couple of things. Firstly, try re-registering ASP.NET with IIS using the ASPNET_REGIIS.exe located in the .NET installation folder: c:\WINDOWS\MICROSOFT.NET\framework\\aspnet_regiis -i   Chances are though, that it won't work, and that you can try and number of command using aspnet_regiis.exe or even uninstalling and reinstalling .

When the Dell engineer said “they’ve asked if you can reinstall the OS” my heart sank. Not because I felt like he was weasling out of work - unusually they were very helpful. Not because installing XP is a hard task, I’ve done it over 100 times on all sorts of hardware. No, the reason I let out a sigh was because this particular laptop, the Latitude X1, has no internal CD/DVD drive.

Recently I found the need to retrieve the key from an existing Exchange Server for a reinstall - the software is legally licensed but the key was somehow lost. A trawl through my registry revealed that the key is stored in an obscure place: HKLM\SOFTWARE\Microsoft\Microsoft Integration\{GUID}\PID3.0 This was the case on a Windows Server 2000 install with Exchange Server 2003 installed, when I get the chance I will test this on Server 2003.

I’ve just removed a domain controller (DC) from my root domain, the very first server not only in the domain, but the forest. The roles were migrating to a newer server, far more up to the job, but it isn’t a job to be taken lightly. If you mess up the root domain, you’ve potentially got problems all the way down your domain hierarchy.   Let me explain; the primary domain controller in a domain (normally the first domain controller) hosts all the FSMO roles.

Incredibly irritating error when you go to install under your user account when you’re using mapped drives for your documents. All our domain users have a userfolder on the server, it’s mapped as z:\ and there is a folder redirection set up. It’s pretty standard in a corporate/domain environment, so why does it cause so many Vista installations to fail?   This is something I’ve run into time and time again and There are a couple of things you can try…sometimes they work individually, sometimes not!

It’s been a while since I’ve posted here, that’s for various reasons, one of which was that I have been preparing for, and taking, my MCSA exams. So here it is… MCTS Windows Vista, Configuring (70-620)  MCP Managing and Maintaining a Windows Server 2003 Environment (70-290) MCP Implementing, Managing and Maintaining a Windows Server 2003 Network Infrastructure (70-291) CompTIA Security+ (SYO-101) Which all add up to an MCSA Windows Server 2003 Security+.

I had an odd problem today, I logged on to begin my day’s work and plugged in my iPod as per normal. iTunes crashes, Vista tries to recover. iTunes closes. iTunes opens. iTunes crashes. Vista tries to recover. As you can imagine that gets tiresome, so I tried repairing iTunes, reinstalling iTunes, installing older versions of iTunes, all to no avail. The solution in the end was to remove Quicktime and do a fresh install.

I’ve finally cracked the installation problems with VS 2003 SP1 on Vista. The problem seems to be that the SP must be installed under the same credentials that Visual Studio was installed. I.e. I installed Visual Studio under the domain administrator credentials, but I run my day-to-day under a standard user credential. When installing the SP1 I was elevating my standard user credential rather than running as the domain admin. I don’t know what difference that makes to anything, but it’s worked!
