Digital Signature Not Found...

[Mike]

When trying to install Symantec Anti Virus on a Windows 2000 Professional
PC, I keep getting the "Digital Signature Not Found" & "unknown software
package" error messages, which then rolls back & doesn't let me install. I
have read the KB article 269651, which explains this & gives a work around.
I'm already running SP4 (article says this was fixed in SP3) & even after
changing the group policy as the article explains, I'm still having no luck!
Any suggestions?

In my computer...properties, set it to ignore digital signatures on driver installation,
and logon using an account that has local admin rights.

It is.
Here's a rundown on it.
Win2k, SP4. Logged in as Domain Admin. I made the change you suggested & it
still doesn't work.
Other oddities, when it starts up, I get a "Windows File Protection"
message, asking that I insert the Win2k CD. I do & nothing happens.
When trying to repair Internet Explorer, it gives me the same "Digital
Signature Not Found" when trying to install IE, Outlook Express, etc!

I have also gone through the steps listed in
http://support.microsoft.com/?kbid=269651 & still get the message.
I really don't want to wipe out & reinstall, as there is software tied to a
large Docutech type printer...
