MaxConcurrentApi

HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Data type

Range

Default value

REG_DWORD

0 | 1–10 ( API calls )

0

Description

Specifies the maximum number of simultaneous, logon-related, application programming interface (API) calls that can be transmitted across a secure channel at any one time.

API calls can be transmitted concurrently only on secure channels that are digitally signed or encrypted.

The default value is optimal for most installations, but you can add this entry to the registry to increase its value. Increasing this value can improve efficiency. However, larger values can exhaust the resources of the domain controller communicating on the secure channel.

Value

Meaning

0

One call at a time on member workstations and domain controllers, and two concurrent calls on member servers.

1–10

Number of concurrent calls. This limit applies to workstations, domain controllers, and servers.

Note Image Note

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits it.
