cannot start exchange 2010 after installing updates

I installed microsoft updates on my exchange server last evening. The exhchange services will not start.  I had to disable the services in order to remote into the machine. I tried starting the services manually. I started MS Eschange Active Directory Topology but I get this error.
Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=3328). Topology discovery failed, error 0x80040a02 (DSC_E_NO_SUITABLE_CDC). Look up the Lightweight Directory Access Protocol (LDAP) error code specified in the event description. To do this, use Microsoft Knowledge Base article 218185, "Microsoft LDAP Error Codes." Use the information in that article to learn more about the cause and resolution to this error. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers.
