Several suggestions for correcting this error:
  • Remote Registry Service started and set to automatic.

  • less than 15 ips bound to the NIC.

  • registry key HKEY_CLASSES_ROOTLDAPClsid presented and correct.

  • checked admin shares

  • replaced riched32.dll

  • Change HKEY_LOCAL_MACHINESystemCurrentControlSetServicesLanmanServerParameters AutoShareServer and AutoShareWks registry values to 1.
One of the solutions that solved this problem is from hidev.com Even though the description does not fit to our situation, our system is a standalone system with no network system attached, yet download the ldap_fix.zip , expand this ldap_missing.reg solved all the problem was mentioned above.
