<div>
I followed the instruction and it doesn't solve the problem.<br />
I see two differences between the note and my case.<br />
1.- I didn't find any trace of the script that is supposed to interfere with Windows activation, so I didn't need to erase neather the registry subkey, nor the resetX and the other files.<br />
2.- When I get the 9th step it continues asking me for Windows activation, as before the first step.<br />
<br />
Any other suggestion PLS !!! ?

<div>
Yes call to Microsoft support &nbsp;and give your win2003 server productkey detials and request them to reactivate this product key and take the new product key in caseof any reinstallation.<br />

<div>
did you use something like xpantispy after the windows installation? since those tools can deactivate the windows activation routine. 
</div>


<div>
No, I didn't, and I'm sure there's nothing strange in the server.<br />
No mathers that, tell me what to do, because I still have SAFE BOOT option that let me login to the server without activation check.

<div>
you should try steps 4-7 of this guide, lets you reactive windows, maybe this will help with you problem.<br />
although you will definetly need to reactivate windows, this is no solution to just make the message disappear.<br />
be sure to have a full system backup before do stuff like this.<br />

you should be able to do those steps in safe boot mode.<br />
hope it works

I have the same problem described in the related question (23065400). I have a Wind. 2003 Ent. Ed. SP1. The difference is that I can't logon to the server. It says:<br />
<br />
&quot;This copy of Windows must be activated with Microsoft before you can continue. You cannot log on until you active Windows. &nbsp;Do you want to active Windows now? &nbsp; To shutdown the computer, click Cancel. <br />
It offers three options: 1.- Yes, 2.- No, and 3.- Cancel. &quot;<br />
<br />
If I click Yes it shows me the traditional &quot;Activate Windows&quot; windows, with grey dark and light backround, and the keys, saying: Windows Product Activation. Windows is already activated. Click OK to exit.<br />
&nbsp;When I click the OK button it logoffs, so I can't go forward.<br />
<br />
Urgent Help pls !!!
