OT:Enrolling with CA Problem

Dear Experts,

I am working on one of INE's security labs and finding one problem. I can't
seem to get a certificate from the CA. Note that I can authenticate the CA
(Get the self signed certificate by the CA) however I can't seem to get a
certificate for my router. I would appreciate any help!

crypto pki trustpoint IE1
 enrollment mode ra
 enrollment url http://10.0.0.100:80/certsrv/mscep/mscep.dll
 revocation-check none

crypto ca authenticate IE1
crypto ca enroll IE1

% Start certificate enrollment ..
% Create a challenge password. You will need to verbally provide this
   password to the CA Administrator in order to revoke your certificate.
   For security reasons your password will not be saved in the
configuration.
   Please make a note of it.

Re-enter password:

% The subject name in the certificate will include: Rack1R3.INE.com
% Include the router serial number in the subject name? [yes/no]: no
% Include an IP address in the subject name? [no]: no
Request certificate from CA? [yes/no]: yes
% Certificate request sent to Certificate Authority
% The 'show crypto ca certificate IE1 verbose' commandwill show the
fingerprint.
