Unable to Open Oracle 11g R2 OEM in Internet Explorer but works in Chrome

Today, when I entered in the office and tried to play with Oracle 11g R2 OEM then it didn't work in Internet Explorer while it was working in Google Chrome and after some investigation I came up with the following command:

C:\Windows\system32>certutil -setreg chain\EnableWeakSignatureFlags 8
Software\Microsoft\Cryptography\OID\EncodingType 0\CertDllCreateCertificateChainEngine\Config\EnableWeakSignatureFlags:

New Value:
  EnableWeakSignatureFlags REG_DWORD = 8
CertUtil: -setreg command completed successfully.
The CertSvc service may need to be restarted for changes to take effect.

C:\Windows\system32>

Finally, it worked great even on IE9.....!!
