Problem logging on Windows XP

[Michele Wallace]

After turning on the computer and clicking on my name the
computer states "logging on" but never connects. An error
msg is then displayed which states, " A problem is
preventing Windows from accurately checking the license
for this computer. Error code 0x800405aa. What do I need
to do?

Hi Michele,

Restart in Safe mode by hitting F8 at startup.

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\Cryptography\Providers
HKEY_USERS\S-1-5-20\Software\Microsoft\Cryptography\Providers

Exit the registry editor, restart normally.
