OEM not working after windows patch KB2661254

See the following for more details:
http://blogs.technet.com/b/pki/archive/2012/07/13/blocking-rsa-keys-less-than-1024-bits-part-2.aspx
The above update will block the use of cryptographic keys that are less than 1024 bits. OEM uses a cryptographic key of 512.

The above article shows a workaround as follows:

1. open a CMD prompt,

2. enter the following command:
  Certutil -setreg chain\minRSAPubKeyBitLength 512

Alternatively, use Firefox instead of Internet Explorer.

Windows DBConsole internal stop. No OC4J admin passwd hence hard stop

 

Enterprise manager cannot be started. The status shows dbconsole is already started:

C:\>emctl status dbconsole
