Take another look at your date. Make sure you have the right year typed in. Try going to the internet time tab on the clock window. Click &quot;Update Now&quot;. This will take a few minutes. If you get an error then the wrong date or time is set in the &quot;Date &amp;&nbsp;Time&quot; tab. <br />
Or, the timezone may be wrong. If the &quot;Internet Time&quot; tab populates, then check the time and date shown to the &quot;date &amp;&nbsp;Time&quot; tab to be sure they are set correctly.<br />
<br />
The Year was off on mine. That was what got me.<br />

<div>
Nope. I have tried that one. I have even gone as far as to put the wrong date in, then re-start, then change it to the correct date but still no luck

So delete your Temporary Internet Files and History, then delete the configuration files from the WindowsUpdate folder, and add Windows Update to the Trusted Zones Site. <br />
<br />
Select Start &gt;&nbsp;Run and type &nbsp; &nbsp;regsvr32 MSXML3.DLL<br />
<br />
Repeat for &gt;<br />
SOFTPUB.DLL<br />
INITPKI.DLL<br />
MSSIP32.DLL<br />
URLMON.DLL<br />
WINTRUST.DLL<br />
<br />
Also find your &quot;Review your update history&quot; page, and see if there are any failed updates showing.<br />
<br />
Select Control Panel &gt;&nbsp;Add/Remove programs.<br />
Check the &quot;Show Updates&quot; box; and see if any of your failed updates are shown. <br />
If they are, uninstall them and retest.<br />

<div>
Check your system time &amp;&nbsp;date in BIOS as well.

Hi All<br />
<br />
Fresh Install Of WinXP Pro on a customers Computer. Legit Disk, install went without any issues. I can surf the net and all seems to be working fine. However Windows Update throws up the Error above and other programs such as AVG Free will not Update.<br />
<br />
A quick look around the net and looking at MS's tips all suggest that I need to Make sure the time and Date Are correct, Both are and are being updated by Internet time (au.pool.ntp.org)<br />
<br />
Found a Post saying re-register Softpub.dll, mssip32.dll, and initpki.dll..............I<wbr /> did this, no good. I would really like to avoid re-installing WIndows on this customers machine as they have 200+Gb of Video files that I would need to move off before formatting. Any Help would be greatly appreciated.<br />

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
