Windows 7 Beta Homegroup (Sharing) Problem

January 19, 2009

If you refuse to create a homegroup during installation, it cannot be created later (even though your PC may be on a home network).

The solution that worked for me with the current beta version (as of writing this post) was to:

a) go to System > Device Manager and delete the network adapter

b) rescan for hardware changes

c) go to Network and Sharing Center and create a homegroup.


Virtual Server could not open its emulated Ethernet switch driver

December 1, 2008

If you’re here that means you’re probably having problems with MS VS 2005 R2.

I have a Broadcome NetXtreme GbE NIC (only one). Unlike blog posts found in top Google searches, my case didn’t involve any change of configuration that I know of. It just stopped working one day. I therefore used a less invasive approach:

a) Update the Broadcom GbE driver (broadcom.com)

b) Uninstall VM Network Services

c) Reboot the box and install VM Network Services again.

This worked for me. Maybe b & c alone would have sufficed.


Hardware Junkie’s Incremental Fix

May 28, 2008

This is totally irrelevant (yeah, I know, not different from the rest of the blog), but I blew few hundred bucks on few new toys for my home:

a) Even more Power Over Ethernet (PoE). I now have a dedicated home network for non-multimedia data.

b) A nice 24″ 16×9 monitor for … I don’t know for what, but I bought it and it looks great even when it’s powered off.

c) A “home” (read: el cheapo) GbE switch for the five data-intensive computers. Wow, I didn’t realize I’d use up all the ports the first day… If the thing had four ports (or if I had six computers), I’d go nuts.

What’s my point? Well, this was one of best investments in my hardware junkie carrier.

Benefits (so far):

  1. Can watch TV and movies over existing Power-over-Ethernet and at the same time copy ISOs or run backup over the new PoE network.
  2. My notebook backup that used to take like 6-7 hours over WLAN (during that time I couldn’t do much with it) now takes 2 hours. I do connect the notebook to GbE LAN now (for some reason the notebook connects to GbE switch at 100Mbps – maybe it’s the cable – but at least the backup server runs at 1000Mbps).
  3. The monitor is awesome. This was the most expensive of the three and I have to say I bought it “just like that” (snapping my fingers) – didn’t do any research, just pointed at the nicest & largest of the monitors in the shop… Ah well. Anyway, the benefit is that I can open like nine shell windows at the same time (of course, I mean without overlapping, cascading, etc.) . And when I start Excel and leave Excel Zoom at 100% I can still see up to column W and row 57.

Windows Live Messenger: Do They Analyze Crash Reports?

May 19, 2008

For close to a year (well, at least six months) I noticed that my Live Messenger crashes easily when network connectivity gets flaky (especially on wireless networks).

I’ve been diligently submitting crash reports, but it’s bene close to a year, so I can’t help but wonder:

a) Does anyone look at those reports?

b) As I’m (probably) not the only person encountering this bug (and to me it happens weekly), why is it taking them so long to fix it?


Windows XP x64 as Hyper-V Guest

May 4, 2008

After another late night of fruitless trying, I have to ask: has anyone managed to get Winows XP x64 to work (including network) as guest OS in Hyper-V?

Last night I tried for 3rd time (less than 3 hours before that I deleted the OS VHD from my HDD :-)), this time using a “Legacy Network Adapter”. The result was consistent with previous attempts (failure). The x64 display drivers seems to work, but others (most importantly, the NIC driver) don’t and after installation Device Manager shows a yellow exclamation mark. Maybe I should just trust the docs – not supported and can’t work.

Out of despair I previously tried the same guest OS on VirtualBox and VMware Workstation 6.x – neither support x64 guests. And this was on Windows Server 2008 SE x64 on which Hyper-V RC0 does support x64 operating systems. I ran that VMware test proggie to make sure and indeed my fairly new Intel Core Duo processor obviously won’t do. Luckily I’ve no this problem with Hyper-V.

Update (2008/09/28): In the meantime Hyper-V RTM (with Windows XP x64 SP2 support) shipped, but for some reason my OS didn’t get the update (http://support.microsoft.com/kb/95005) so I just wasted a day on  troubleshooting  this stuff…  Wonderful.


Getting Windows 2003 Service Pack into a Hyper-V Guest VHD

May 3, 2008

You install Windows 2003 Hyper-V guest and you can’t install add-ons required to get access to the network because it’s a pre-SP1 Windows OS. You can’t copy/download the SP to the VM because it’s got no network adapters.

Solution 1: the VHD mount script posted here. Shut the VM down, mount the VHD and copy the SP (and whatever you want) to that disk. I used the PowerShell version because it’s shorter and – of course – again got stuck with the unsigned PowerShell script problem. This time, though, I reused the “worst practice” workaround that I wrote about here. Done! To unmount, Save As… and add “un” before “mount” in the last line.

Solution 2: In your Hyper-V manager right-click on your (host) server and select Edit Disk.

So far I’ve been happy with Hyper-V although I’ve unnecessarily wasted too much time trying to get Windows XP x64 going (not supported).


No Hibernate / Suspend with Hyper-V

April 25, 2008

After reading few good experiences with Windows Server 2008 I decided to use it on my new workstation. I also enabled Hyper-V, but then I discovered that my power saving settings are gone. You can shutdown and that’s pretty much it as far as power saving goes.

Now I found out (here) that when Hyper-V is enabled, power saving actions such as hibernate and suspend are not available. Oh, well..  If it’s worth it, I’ll stick with it. If not, I might consider some other virtualization solution.
