Now this may seem odd as you’ve also probably already got Administrative rights on the PC?

This is a new safety measure originally introduced in Vista to stop rogue (spyware) applications from modifying hosts and redirecting traffic to other sites.

However, you can still modify the file:

Right Click on “Command Prompt” icon, and select “Run as Administrator”

cd \windows\system32\drivers\etc

notepad hosts

You should now be able to save the file without any problems.

Believe it or not, it appears that the problem is related to smart card authentication (which isn’t even used on the site).   On the machine establishing the connection – go into the remote desktop properties, under the Local Resources tab, press the More button.   If you deselect “Smart Cards” – the problem is fixed

There is a long discussion of the problem with other possible solutions over at asp.net if the above fix doesn’t work for you.

Log on as another user with Administrative rights.

Start regedit and go to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Here you’ll see a list of SIDs for each user profile, and you should find there are two with the same SID, however one ends with “.bak”.   You need to swap these around – essentially restoring the backup SID.

Once swapped – set both State and Refcount to 0 and then reboot. Fingers crossed, everything should be back to normal!

For a good step through of the process – take a look at this walkthrough.

The most successful solution I’ve seen so far is to download each update and manually install it.   I’m still searching for a better solution as this could be very tedious for a lot of PCs!   I’ll report back when I have further information.

For now – here is some further reading:

The Vista PC in question had 6 Windows Updates all failing with the same error code : 0×80071a2c. After several attempts at rebooting and installing the updates, I decided to delve deeper.

Looking in c:\windows\windowsupdate.log I found the following errors:

WARNING: Got extended error: “POQ Operation HardLinkFile OperationData \SystemRoot\WinSxS\x86_microsoft-windows-help-browser.resources_31bf3856ad364e35_8.0.6001.18702_he-il_9475a540718490ed\browser.h1s, \??\C:\Windows\Help\Windows\he-IL\browser.h1s”

Now, from what I found, the POQ error is due to Windows Update creating a hardlink between the two “browser.h1s” file locations specified above.

But the source file above doesn’t exist in the winsxs folder?   At this point I had a guess..   The file mentions “browser.resources” and also “8.0″.    Could this be Internet Explorer 8.0?   If so – it isn’t installed on the machine and could explain the error.

So..   Installed IE 8 and the patches then went on fine!

Office XP will run on Windows Vista fine.

1) Start an Administrator command prompt (Start, All Programs, Accessories – right click on command prompt and select “Run as Administrator”).

2) Type “powercfg /hibernate on”   (without the quotes)

3) Reboot

The option should be available again now!

Try and run telnet on vista and you’ll be greeted with a “command not found”

It’s easiyresolved – can be added using programs and features (yup – premove programs with a different name).

But why has it been removed?  I can’t see it as a security flaw? A telnet “server” – yes, but a telnet client??

At least it’s still in there somewhere….
