This article describes an issue that occurs when applications use Active Directory Service Interfaces (ADSI) APIs in Windows Server 2012 R2. A hotfix is available to fix this issue. The hotfix has a prerequisite.
Cause
This issue occurs because ADSI doesn't support time-outs when LDAP calls are made to domain controllers. Instead, a NULL value is passed in most of the API calls. This causes Wldap32.dll to wait until a response is received from the server.
Affected applications
The following applications are reported to have encountered this issue:

Prerequisites
To apply this hotfix, you must have April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) installed in Windows 8.1 or Windows Server 2012 R2.
Registry information
This hotfix introduces a default time-out at the ADSI (Active Directory Service Interfaces) level, it may cause application compatibility issues in which a legitimate LDAP query takes more than 10 minutes to respond in some rare scenarios. After you install this hotfix, all such LDAP queries will time out. Therefore, there is a registry switch to disable or enable the default time-out.
Registry key path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ADSI\Tracing
Registry key name: DisableAdsiTimeout
Type: REG_DWORD
Notes:
-
If the registry key is not present, global time-out is set to default of 10 minutes.
-
If the registry key is present with a value (0), global time-out is set to default 10 minutes.
-
If the registry key is present with a non-zero value, global time-out is disabled and it reverts to the previous behavior (there is no timeout and it is timeout indefinite).
Restart requirement
You may have to restart the computer after you apply this hotfix.
Hotfix replacement information
This hotfix doesn't replace a previously released hotfix.
Status
