Consider the following scenario:
The network path was not found
Here are some sample LDAP-related applications that are affected by the issue:
Active Directory Users and Computers MMC snap-in
Active Directory Domain and Trusts MMC snap-in
Active Directory Sites and Services MMC snap-in
ADSI Edit MMC snap-in
Group Policy Management MMC snap-in
DHCP MMC snap-in
Microsoft System Center Configuration Manager 2007 Administration Console
Authorization Manager (AzMan)
The issue occurs because of a compatibility issue between LDAP and Remote Desktop IP Virtualization.
The LDAP module's hard-coded behavior is to use an internal socket that is bound to the IP address 127.0.0.1. However, Remote Desktop IP Virtualization rebinds the socket to a virtualized IP for the session or the program. This behavior causes a connection failure in the LDAP component.
Hotfix informationAfter you install the following hotfix and configure a registry subkey, the LDAP module will bind and connect an internal socket to any loopback address that is provided in the registry by a user. The address provided must be a loopback address (the address starts with 127) and should not be 127.0.0.1. A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
