Please help - Can not use/export private key after domain change

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

I have a self signed certificate in Windows XP (private/pulic key
pair). Recently my company changed my login domain (keeping the same
user name, password and Profile directory). But after that I can not
use my
certificate (private key). Looking at the password manager, it shows
the certificate, also when I view it, it says that I have private key
corresponding to the certificate. But when I try to export it greys out

the option for private key export saying "The associated provate key
can not be found. Only the certificate can be exported." I guess the
reason might be that the key was encrypted based on password + domain
name. Just my guess, based on my limited understanding from what I
found on the net:

"Windows XP protects you against such attacks. Windows XP encrypts the
private key with a derivative of your password. If the password is
changed and you don't provide the old password, access to the public
key will be permanently blocked, and you or a thief can no longer
decrypt files with this key."

Is the only way to recover the key to ask for switching back to the old

domain ? Please advise, I would really be very greatful for any help to

recover my key.

Thanks a lot,
Sandeep
