problems after installing Windows XP SP2

I have just installed Windows XP SP2 and rebooted my Windows XP Pro
workstation and I get the following message when I click on my ID to login:

a problem is preventing Windows from acurately checking the license for this
computer. Error code: 0x8007007f.

Has anyone seen this before? or does anyone know what the solution may be?

Hi Mal,

Start the computer in Safe mode by hitting F8 at bootup. Logon as
administrator.

Start/run regsvr32 regwizc.dll
Then start/run regsvr32 licdll.dll

If this doesn't help try these steps:

Start/run regedit. Delete the following keys:

HKEY_USERS\.DEFAULT\Software\Microsoft\Cryptograph y\Providers
HKEY_USERS\S-1-5-20\Software\Microsoft\Cryptography\Providers

Exit the registry editor, restart normally.
