The update process fails when you install the cumulative update package that is described in KB article 977349 on an Office Communications Server 2007 R2 server

SYMPTOMS
You install the cumulative update package that is described in Microsoft Knowledge Base (KB) article 977349 on a Microsoft Office Communications Server 2007 R2 server, this server is part of an Active Directory environment that has a large Active Directory database. In this situation, the update process fails. Additionally, you find the following error message in the QFE_DBSetup.log file:

Attempting to discover BackEnd SQL instance from AD.

LDAP Query (ConfigurationNamingContext): <LDAP://CN=Configuration,DC=DCName,DC=com>((&(objectClass=msRTCSIP-Pool)(msRTCSIP-PoolType:1.2.840.113556.1.4.803:=2)(msRTCSIP-PoolDisplayName=poolname)));distinguishedName,msRTCSIP-BackendServer;subTree

LDAP Query (RootDomainNamingContext): <LDAP://DC=DCName,DC=com>((&(objectClass=msRTCSIP-Pool)(msRTCSIP-PoolType:1.2.840.113556.1.4.803:=2)(msRTCSIP-PoolDisplayName=poolname)));distinguishedName,msRTCSIP-BackendServer;subTree

Could not locate SQL instance from AD.


Note
By default, the QFE_DBSetup.log file is located in C:\User\ User who installed the update \AppData\Local folder.
CAUSE
This problem occurs because of a time-out that occurs when the Dbqfeupdate.wsf update script runs the following LDAP query:
(ConfigurationNamingContext): <LDAP://CN=Configuration,DC=DCName,DC=com>((&(objectClass=msRTCSIP-Pool)(msRTCSIP-PoolType:1.2.840.113556.1.4.803:=2)(msRTCSIP-PoolDisplayName=ocs2007r2pool)));distinguishedName,msRTCSIP-BackendServer;subTree
The Dbqfeupdate.wsf script runs an LDAP query on the non indexed objectClass attribute of Active Directory. This query may take several minutes to complete on a large Active Directory database. Therefore, the time-out occurs.

Note The default time-out value in the script is 300 seconds.
RESOLUTION
To fix this problem, apply the following cumulative update:
