Configuration error setting up Xbox 360 as media extender with Windows 7 media PC

Anonymous

Currently running Windows 7 x32.

Until recent update to XBox 360, all was working fine using 360 as a media centre extender.

Now fails and when I try to resestablish a connection a configuration error arises.

Network connection seems fine as I can still stream media fine to Xbox dashboard. Media centre seems to find and install extender OK, just fails at configuration.

Have tried with AV and fiewalls disabled (Karspersky) with no success.

Frustrating as was working fine, now the functionaility is lost.

ANy help would be greatly appreciated

For months, I experienced a problem exactly like the one described here, but I've finally fixed it on my machine and I believe I've got to the core of it.

The fix (this is for Windows 7, may also apply to Vista):

Find your 'Users' folder (usually c:\users).
Under 'Users' folder, go to subdirectory 'Default\AppData\Local\Microsoft\Windows Live'.

Note: The directory may not exist, but I've seen the extender problem only on a computer that does have it.

Inside this directory, there are additional subdirectories (e.g. 'Bici' and 'SqmApi'). Inside, there are several files with .sqm extension. THE PROBLEM IS WITH .SQM FILE PERMISSIONS. Specifically, the profile service has no permission to access or copy the files when creating a new profile.
To fix the permission issue, perform the following actions on each of SQM files.

Note: Inheriting parent container permissions will grant Everyone read access to the files.

a. Right click on the file, select Properties.

b. Select Security tab, click on Advanced button

c. Select Permissions tab (selected by default), click on Change Permissions... button.

d. MARK THE CHECKBOX: Include inheritable permissions from this object's parent.

e. Press OK button several times to close all the dialogs.

Then, setup Media Center Extender per regular instructions.

While these steps successfully repaired my computer, they may not apply to every situation. My advice is to run the following diagnostics steps:

Use Control Panel to create a new user account.
Use 'Switch user' (or Log off/Log on) in an attempt to log into this new account. This attempt will fail (if not, you may have a different problem).
Examine 'Application' event log (under 'Windows Logs') for the relevant events.

On my machine, I've got several warnings with Event Id 1509 about the files that couldn't be copied from Users\Default to Users\TEMP due to access denied errors. These were .sqm files with incorrect permissions.

do you have fingerprint reader software on your computer? this is known to

interfere. you will need to uninstall it. other software that pops up a window

can cause this failure as well.

|The problem, as indicated in the Event Log, is "The Media Center

|Extender session was terminated because an unauthorized window opened

|in the session.

This seems to be my exact problem, but I do not know how to accomplish step 6.

To recap:

I linked my Windows 7 Media Center to my Xbox 360, and the setup completed. However, as soon as the xbox connects to the computer, it kicks out and says on the Xbox, "A program on your Windows Media Center PC has caused the Xbox 360 to disconnect."

The problem, as indicated in the Event Log, is "The Media Center Extender session was terminated because an unauthorized window opened in the session."

I have been fighting with it all night, and can't seem to find the solution. Any help to resolve this issue would be much appreciated.

I finally solved my issue. I was getting the error;

"Media Center Extender Setup cannot create an account for the Extender with ID: uuid:10000000-0000-0000-0200-xxxxxxxxxxxxxxx.

Error: Only part of a ReadProcessMemory or WriteProcessMemory request was completed."

This was down to the fact I had some banking security softwate installed called "Rapport". No errors were being thrown, just a question of trial and error. I knew it was something to do with account creation.

Uninstalled Rapport and everything is working!

I had a similar problem and was getting Event ID 545. I was also getting numerous mcx-1 accounts being created. After trawling the Internet and many days of searching I resolved my issue by removing a piece of software called Trusteer Rapport.

This software is being recommended by many banks. It seems reading the posts that it causes many issues.

On removing it and cleaning out all my mcx-1 accounts (using the Adminsitartor account in Win 7), I tried again and all worked perfectly.

Hope this helps.

Thanks for the tip on Trusteer Rapport,. Removing it got rid of the 545 error on my set-up and allowed the extender to install.

Trusteer is a good product, maybe essentail for secure banking etc, and Ive opened an incident with that company just to flag this to them.

Thanks once again, as I can see from all the inputs and efforts here, its not easy to get to the bottom of these type of problems
