I'm trying to edit the hosts file on Windows Server 2008.

I right clicked on Notepad and Ran as Administrator, then opened the hosts file, but when I try to save it I get the following error message:

Cannot create the C:\Windows\System32\drivers\etc\hosts file.
Make sure that the path and file name are correct.

Next I checked the permissions for Administrators on the hosts file. The following are checked as Allow:

• Full Control
• Modify
• Read & execute
• Read
• Write

When I edit the permissions, all the check boxes are gray and not editable.

Next I check the file Owner of the hosts file. The Current owner is SYSTEM. When I try to edit the Owner I get the following message.

You only have permission to view the current owner on hosts.

The Windows documentation states

Ownership can be taken by:

An administrator. By default, the Administrators group is given the Take ownership of files or other objects user right.

In the Local Security Policy under the User Rights Assignment section, Take ownership of files or other objects is set to Administrators.

Why wouldn't I be able to change ownership to edit the hosts file?

I have a server with Windows Server 2008 Standard x64 Edition installed. This has been installed and running for several months and I have been able to successfully install previous Windows Updates. I have two pending updates that fail to install.

• (KB967723) Security update for Windows Server 2008 x64 Edition

• (KB976098) Update for Windows Server 2008 x64 Edition

Fails with Error code: 80070490

Followed this off Microsoft support site, which basically says to repair Windows with the install DVD. When I get to the step to select upgrade I get the following error.

Upgrade has been disabled. The upgrade cannot be started. To upgrade, cancel the installation and then choose to upgrade to a version of windows that is more recent then the version you are currently running.

So basically feel like I've hit a dead end with out doing a complete reinstall. Any ideas ?

Is there a way to reset the auto incrementing value of a field so it starts back at 1 ?

+-------+------------------+------+-----+---------+----------------+
| Field | Type             | Null | Key | Default | Extra          |
+-------+------------------+------+-----+---------+----------------+
| id    | int(10) unsigned | NO   | PRI | NULL    | auto_increment | 
| name  | varchar(45)      | NO   |     | NULL    |                |

Can a standard cat5 cable transmit at a speed of 1000 Mbit/s ?

I've asked several people I know in the networking field and received different answers. I know a cat5 "works" on a Gigabit network but does it give the same performance of a cat5e or cat6 cable ?
