If you have strange name resolution on your network, it could indicate a DNS poisoning, DNS hijacking, or it could just be that you need to clear your cache.
First, check your DNS forwarders to make sure they are set up appropriately. If you don’t trust your DNS provider, or have any reason to suspect they may be having an issue, you can temporarily change your forwarders to a public DNS server (recently I’ve been really digging OpenDNS (208.67.222.222 and 208.67.220.220 – but there are certainly others out there). Once you get things straightened out you can always switch back to whoever you had originally.
A good place to start, though, is to clear out all your caches. Here are some of the places you might need to check for (and clear) the bad entries:
– Your local cache (ipconfig /flushdns)
– Your AD Domain Controllers (Go to the DNS console, turn on advanced view, right click on the cache and choose “clear cache”)
– Your ISA server (you must use the command line tool dnstools /c – you need to download this from Microsoft – search for dns cache tool for isa or look at isatools.org)
– Other proxy-like appliances installed in your enviroment
As always, when trying to solve this type of problem, “be the packet”: follow the path from you to the Internet and leave no stone unturned along the way.
Do your force the PCs in your office to shut down when not in use? If you do you can save money on the electricity you consume and pay for, but will lose some manageability of the PCs. Best bet is probably a hybrid approach – set the monitors to go to sleep and leave the PCs on all night – or at least most of the night.
Use this calculator to estimate your energy and dollar savings from activating power management on your computer monitors and your PCs. Enter the number of units to be power managed and the price of electricity (a national commercial average of 7.1 cents per kWh is the default).

Problems occur after installing XP SP3 or Vista SP1 with a Norton 2008 product installed.
Numerous registry keys are added when you upgrade to Windows XP Service Pack 3 or Windows Vista Service Pack 1 with a Norton product installed. Because of these registry keys, you may experience one or more of the following symptoms:
* Windows Device Manager is empty
* Missing Wireless network adaptors or other hardware devices
* Unable to connect using a wireless adapter
During the upgrade to Windows XP Service Pack 3 or Windows Vista Service Pack 1, a tool called Fixccs.exe creates a series of registry keys in many locations (some of them within the Symantec registry keys) but is unable to remove them.
Symantec has developed a tool to remove the registry entries that were added during the Windows XP Service Pack 3 or Windows Vista SP 1 upgrade. Download and run the tool to automatically remove the registry entries.

There’s a lot of OS religion out there – most of it based on purely subjective data.
Engadget posted a comparison chart of OSX vs. Vista features. Interesting that by their scoring OSX takes a win with a score of 46 while Vista gets a close 41. I don’t think they weighted important features higher than features that no one really cares about. For example, stereo Bluetooth and video editing get the same points-value.
Also interesting is that they include the fact that neither has antivirus built-in but don’t mention anti-spyware.
