0x80072ee7 when connecting over wireless network

For the past few days I have been getting 0x80072ee7 errors whenever I
attempt to do a scan on windows update. I have discovered today that if I
connect to my ADSL router (Netgear DG834) using an ethernet cable instead of
through wireless it seems to work. Both connections are protected using the
Windows firewall and no other sites have a problem. It was working until a
few days ago over wireless and I have not changed any settings on my router
or my computer. Does anyone have any suggestions that I can try. I rarely
connect by ethernet to my router and this will probably mean that I automatic
updates will not work either.

From the Windows Update v.6 Troubleshooter:

" Problem description
This error may occur when the client PC tries to resolve a URL for the
Update site and is unable to find the correct IP address.

Resolutions
1. Clear your local proxy cache on the machine.
Click on Start, and then click Run.
Type cmd in the Open box to get a DOS prompt.
Type proxycfg -d at the command prompt, and press Enter.
Type proxycfg -u at the command prompt, and press Enter.
Now try the site again.
This should work right away, with no other restarts needed.

2. Try using different DNS servers. It's possible that the ISP's DNS
servers are having problems; although if this is the case, it should
only be temporary as the ISP should be working to correct any issues.
Contact ISP or network administrator for more information regarding DNS
configuration.

3. A misconfigured Proxy/Firewall can cause this problem. Double-check
the Proxy/Firewall settings. For help configuring Proxy/Firewall refer
to documentation or contact the manufacturer.

4. Check your HOSTS file and make sure you do not have any static IP
entries for the Windows Update web site listed in the file
Depending on the operating system the HOSTS file can be found in:

Windows NT/2000 - C:\Winnt\system32\drivers\etc
Windows XP - C:\Windows\system32\drivers\etc
To view the HOSTS file, you may need to associate the HOSTS file with
Notepad. To do so, right-click the file, select open or open with, and
select Notepad from the list of programs. If the HOSTS file contains a
static IP address associated with Windows Update, comment the entry by
adding the # sign at the beginning of the entry or delete the entire
line and save changes to the HOSTS file.
Applications like web accelerators, Tweak Master DNS, Spyblockers, etc.,
can add static IP entries for the Windows Update site into your HOSTS
file, which cause Windows Update to fail. "

I forgot to mention, I have tried the remedies suggested by the Windows
Update troubleshooter, none of which had any effect. I also neglected to
mention that I am using a fully patched Windows XP SP2.

Thanks for the suggestion but no joy.

Hi

Can you send %windir%\WindowsUpdate.log (one word) from the client machine
that is encountering this problem?

Thanks,

Hi

I had the same problem.
For DNS server the ip adres of my router was filled in, i changed this to
the ip adres of my ISP this solved the problem for me.

I had the same wireless issue - no problem when direct connected but wouldn't
scan on wireless. I tried all the other suggestions that came up except the
MTU cahnge. Running wireless in DCHP mode didn't give the option to change
MTU on the router, but manually setting MTU to 1452 according to this
procedure from KB 900926 instantly fixed the problem PC. (Many other options
related to manually changing MTU can be found by searching: MTU XP
registry.)

Method 3: Set the MTU size for the network interface manually
If you set the MTU size for a network interface manually, this setting
overrides the default MTU for the network interface. The MTU size is the
maximum packet size in bytes that the transport will transmit over the
underlying network.

This method affects packets sent to all destinations and may significantly
affect the performance, depending on the MTU size that you set.

To set the MTU size for the network interface, follow these steps:1. Click
Start, click Run, type regedit, and then click OK.
2. Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\<ID for network interface>
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type MTU, and then press ENTER.
5. On the Edit menu, click Modify.
6. In the Value data box, type the value of the MTU size, and then click OK.
7. Quit Registry Editor, and then restart the computer.
