General Parameter Registry Keys -- Non-Refreshable

The following keys control certain features or behaviors of Access Connect. The keys in this section are not refreshable, meaning that changes do not take effect until the Access Connect service is restarted.

These keys should be added in the following registry location:

\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ExtremeZ-IP\Parameters4\NonRefreshable

ActiveDirectoryComputers

Description: When configuring Access Connect to support Kerberos constrained delegation for network reshare volumes, if the computer object for the server that is running Access Connect is not located in the default “Computers” container in Active Directory, it is necessary to edit this registry key so that Access Connect can construct the correct distinguished name for the server's computer object.

The Access Connect service can identify the server common name (CN) and the domain component (DC) segments of the distinguished name, so the ActiveDirectoryComputers registry key is where the custom organizational unit (OU) segments of the distinguished name can be entered.

e.g. If the canonical name of the Access Connect server’s computer object is: yourdomain.com/Marketing/3rdFloor/importantComputer

The distinguished name would be: CN=importantComputer,OU=3rdFloor,OU=Marketing,DC=yourdomain,DC=com

Since Access Connect can identify the CN=importantComputer and DC=yourdomain,DC=com segments, only the OU=3rdFloor and OU=Marketing segments would need to be added.

In this example, it would be necessary to set the value of the ActiveDirectoryComputers registry key to 'OU=3rdFloor,OU=Marketing’ (without the quotes) in order for the Access Connect service to work with the importantComputer computer object.

• Default:
• Type: string
• Refreshable: No

AllowNonIndexedSearches

• Description: Specifies whether or not the server allows searches that do not contain "name" as one of the criteria. These searches can be very slow and can cause the server to use a great deal of CPU while the search is occurring. Turning this key off will cause the server to reject search requests that don't include "name" as one of the criteria, and the server will send appopriate warning messages to the user attempting to perform these types of searches.
• Default: On
• Refreshable: No

CheckNtfsLastAccessUpdate

• Description: Whether or not the server checks the status of the NtfsDisableLastAccessUpdate Windows registry setting when the server starts up. If this key is enabled and NtfsDisableLastAccessUpdate is off, Access Connect will log a warning to the Windows Event Log.
• Default: On
• Refreshable: No

ClientDisconnectTime

• Description: Specifies the number of seconds the server will wait for an unresponsive client to disconnect before ungracefully terminating the connection.
• Default: 30
• Refreshable: No

ClientDisconnectAtShutdownTime

• Default: '<installationPath>\ExtremeZ-IP dtSearch Indexes\'. It will be empty on a Cluster.
• Type: string
• Refreshable: No

SupportAFP3

• Description: Enables support for AFP 3.1 (disabling this feature forces Access Connect to support AFP 2.2 only). AFP 3.1 features include support for filenames over 32 characters, file sizes over 2GB, and Unicode strings.
• Default: On
• Refreshable: No

SupportAFP32

• Description: Enables support for AFP 3.2 (disabling this feature forces Access Connect to support AFP 3.1 if the SupportAFP3 key is enabled). AFP 3.2 features include support for Access Control Lists (ACLs) and extended attributes.

IPAddress

• Description: Specifies a subset of one or more available IPv4 addresses for use by Access Connect. If this key does not exist, Access Connect will function on all active server IPv4 addresses. This key is of type REG_MULTI_SZ (multi string) and must be added using "regedt32.exe". The value of the key should be a list of IPv4 addresses separated by linefeeds (e.g. "192.168.1.101"). This setting is honored on clustered servers running Access Connect 5.2.2 or later, but is ignored on clustered servers running earlier versions of Access Connect.
• Default: Does not exist
• Refreshable: No

IPv6Address

• Description: Specifies a subset of one or more available IPv6 addresses for use by Access Connect. If this key does not exist, Access Connect will function on all active server IPv6 addresses. This key is of type REG_MULTI_SZ (multi string) and must be added using "regedt32.exe". The value of the key should be a list of IPv6 addresses separated by linefeeds (e.g. "2001:1::6045:1ff7:ed9c:91b2"). This setting is ignored on clustered servers.
• Default: Does not exist
• Refreshable: No

IPv6Enabled

• Default: On
• Refreshable: No

IPv6Strict

• Description: Controls protection level on IPv6 connection. The valid values are 10 (unrestricted), 20 (default), and 30 (strict). If the value is set to 30 (strict), only same site local IPv6 address can be connected. If the value is set to 20 (default), both same site local & external IPv6 addresses can be connected. If set to 10 (unrestricted), any IPv6 addresses can be connected including Teredo NAT Traversal address.
• Default: 20
• Refreshable: No

LogMemorySettingsNotOptimized

• Description: Controls whether Access Connect logs messages "Memory settings for this server are not optimized correctly".

For maximum search performance, assuming available system RAM, this is best set to be equal to or greater than total size of all search index files on the server. An index file containing 1 million files should be about 32 MB in size. Note that this setting is a maximum RAM cap. If your server only contains 20 MB of index files, Access Connect search will only use 20 MB of RAM, even if this is left at the default 200 MB setting.
• Default: 200
• Refreshable: No

MaxOutstandingTickles

• Description: The maximum number of tickles the client can fail to respond to before the server terminates the connection.

RenameLogAtStartup

• Description: Access Connect Debug Log will be renamed (saved off) at every service startup.
• Default: 1
• Refreshable: No

SupportAFP33

• Description: Enables support for AFP 3.3 (disabling this feature forces Access Connect to support AFP 3.2 if the SupportAFP32 key is enabled).
• Default: On
• Refreshable: No

SupportFileIDs

• Description: When enabled, the File Server will support file ID operations.
• Default: On
• Refreshable: No

SupportNetworkReshares

• Description: When enabled, the File Server will allow resharing of remote servers and shares.

ServerUsesDefaultTypeCreator

• Description: Prior to Access Connect 4.0.3, files with no type and creator information were given a default type/creator of text/dosa. In version 4.0.3, this default behavior was changed so that files with unknown type and creator received a blank type and creator. This change was made for performance reasons - this allows for greater performance when copying many small files, particularly over Gigabit. However, some customers may rely on the previous default behavior, where unknown files would appear as text. For these customers, the ServerUsesDefaultTypeCreator registry key should be enabled.
• Default: Off
• Refreshable: No

ServerRevertsToSystemForAFPInfo

• Description: Fixes a rare problem where the default mechanism for accessing finder info is extremely slow on particular systems. The problem would manifest itself as extremely poor performance - on the order of minutes to simply display the root of the mounted volume. Please contact GroupLogic Support before enabling this key.
• Default: Off
• Refreshable: No

StartFileServerAtStartup

• Description: Whether or not the Access Connect file server should be brought online at service start.
• Default: On
• Refreshable: No

StartPrintServerAtStartup

• Description: Whether or not the Access Connect print server should be brought online at service start.
• Default: On, unless Access Connect was upgraded from a previous version of Access Connect that did not a print server license
• Refreshable: No

SupportUNIXPermissions

• Description: Whether or not the server supports UNIX permissions.
• Default: Off
• Refreshable: No

StartupDelaySeconds

• Description: If this key is set, Access Connect will wait the specified number of seconds after its Windows service starts before actually starting the Access Connect file and print services. This can be used in cases where Access Connect is dependent on network or storage resources that take longer than normal to become available when a server is started.
• Default: 0
• Refreshable: No

ServerLogsPerformanceStats

• Description: Specifies whether or not the server loads the performance data helper DLL at startup and uses that DLL to output performance statistics to the log.

• Default: On
• Refreshable: No

TickleTime

• Description: Specifies how often, in seconds, the server will send a "tickle" packet to the client to keep the client connection alive. This packet will only be sent if there has been no other traffic on the socket on that time.
• Default: 30
• Refreshable: No

ThreadPoolDefaultStackSize

• Description: The default stack size of threads in the thread pool, in bytes. A value of 0 indicates that threads created in the thread pool should use the default process stack size (usually 1MB).
