Finding a solution for the 0x8024502d error



This is a fairly common Windows Update error and hopefully this article will help you resolve the problems you are having.

The 0x8024502d error code typically occurs because an incorrect character exists in the proxy override settings.

But there are some other reason and these are listed below.

 

 

 

What causes Error 0x8024502d


# Incorrect character exists in the proxy override settings.

# A mis-configured Proxy/Firewall can cause this problem.

# You are trying to access Windows Update using VPN. The website and Automatic Update may not function properly.

# The corporate environment does not have autoproxy implemented.

# Your workstations sit behind a Microsoft ISA server.

To try and resolve the error 0x8024502d, use the following tips... After each tip test to determine whether the issue is resolved.



Resolution Suggestion One:

# Remove invalid characters from the proxy exception list and then clear the proxy cache.

1. Open Internet Explorer.
2. On the Tools, select Internet Options.
3. Click on the Connections tab.
4. Click on the LAN Settings.
5. Click on the Advanced button.
6. Please delete any entry in the Exceptions section.

Next, clear your proxy cache.

1. Click on Start, and then click Run.
2. Type cmd in the Open box to get a DOS prompt.
3. Type proxycfg -d at the command prompt, and press Enter.
4. Type net stop wuauserv at the command prompt, and press Enter.
5. Type net start wuauserv at the command prompt, and press Enter.
6. Now try the site again.

-----------------------------------------------

Resolution Suggestion Two:

# Reconfigure or update your firewall program.

Double-check the Proxy/Firewall settings. Add the following urls to the exception list within your Firewall/Proxy:

http://*.windowsupdate.microsoft.com
https://*.windowsupdate.microsoft.com
http://download.windowsupdate.com

For help configuring Proxy/Firewall refer to documentation or contact the manufacturer.

-----------------------------------------------

Resolution Suggestion Three:

# VPN and Proxy.

You are trying to access Windows Update using VPN. The website and Automatic Update may not function properly.

Autoproxy is not picking up the wpad.dat proxy configuration file to determine the proxy to be used for the target URL. Thus we are going with no proxy!

1. Try to access Windows Update while not using VPN connection.
2. Use the proxycfg tool to specify a proxy server to use (proxycfg.exe -p <proxy server>). (contact your network administrator to find out the name and port of this proxy.)

-----------------------------------------------

Resolution Suggestion Four:

# Run proxycfg to tell WU about your proxy.

The corporate environment does not have autoproxy implemented.

Automatic Update will always do autoproxy detection and thus if that returns no proxy, it will try to use no proxy. Use the proxycfg tool to specify a proxy server to use (proxycfg.exe -p <proxy server>). Please contact your network administrator to find out the name and port of this proxy.

-----------------------------------------------

Resolution Suggestion Five:

# Your workstations sit behind a Microsoft ISA server...

There appears to be a client side proxy setting incongruence...

# Other suggestions found in Newsgroup postings:

# ONE

I received the 0x8024502d error in windows update using XP home edition sp1.

My solution was this:

I had just before connected to another laptop using infrared, this connection was still 'active' in my network places\network connections. When I deleted that one windows update worked again.


#TWO

I resolved the error by enabling all of Norton Internet Security automatic startup options through msconfig.
