CertInfoCacheSize

HKLM\SOFTWARE\Microsoft\MSMQ\Parameters

Data type

Range

Default value

REG_DWORD

0x0–0xFFFFFFFF ( certificates )

0x35 (53)

Description

Determines the maximum number of certificates stored in the certificate cache, which stores information about certificates found in incoming messages. This cache helps Message Queuing authenticate incoming messages more quickly.

If the cache is full (that is, the number of certificates equals the value of the CertInfoCacheSize entry) when the next certificate arrives, Message Queuing deletes half of the certificates in the cache. The oldest certificates are deleted first.

Note Image Note

Entries in the certificate cache are not subject to an expiration time. Certificates are deleted from the cache only when the cache is full.

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 the registry.
