Services For Macintosh (SFM) does not appear in the Registry until you install SFM using the Network icon in Control Panel. After installation, the SFM value entries appear under several Services subkeys: AppleTalk®, MacFile, MacPrint, and MacSrv. You should let the system maintain entries in the MacPrint or MacSrv service. However, the AppleTalk and MacFile services contain definable parameters described in this section.
You should use the Network icon in Control Panel to configure SFM, and use File Manager to administer file services, Server Manager to administer server services, and Print Manager to administer print services for SFM.
SFM is included with Windows NT Server and the AppleTalk transport service is on the Windows NT Resource Guide disk.
The values for the AppleTalk service are found in the following Registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AppleTalk
For changes to take effect, you must restart the File Server for Macintosh using the Devices icon in Control Panel.
The settings in the Linkage subkey and the TCP/IP settings in the Winsock subkey for AppleTalk are maintained by the system and should not be changed by the user.
The entries for AppleTalk that are specific to network adapter cards are found under the following Registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
\AppleTalk\Adapters\adapter_name
There is one subkey for each adapter that is AppleTalk-compatible on the computer. These entries are found in each Adapter_Name subkey.
For changes to take effect, you must restart the File Server for Macintosh® using the Devices icon in Control Panel.
AarpRetries REG_DWORD Number
Specifies the maximum number of AppleTalk address-resolution protocol packets to be sent by the AppleTalk protocol.
Default: 0xa
DdpCheckSums REG_DWORD 0 or 1
Tells the AppleTalk protocol whether to compute checksums in the DDP layer. If this entry is 1, the AppleTalk protocol uses sums in the DDP layer.
Default: 0
The MacFile subkey contains the main entries for the AppleTalk File Protocol (AFP) server. All configuration information for the file server is in the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MacFile
The MacFile\Parameters subkey includes Type_Creators, Icons, and Extensions subkeys. You should let the system maintain entries in the Icons or Extensions subkeys. This section describes value entries for the Parameters subkey.
The Registry path for MacFile parameters is the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MacFile\Parameters
The following value entries specify server options, which can be set from the Server Manager. All other entries are added to the Registry when changes to the default values occur.
For changes to take effect, you must restart the computer.
MaxSessions REG_DWORD 1 to unlimited (0xffffffff)
Specifies the maximum number of user sessions that the file server for Macintosh can accommodate.
Default: 0xff (255 in decimal)
PagedMemLimit REG_DWORD 1000K to 256000K
Specifies the maximum amount of page memory that the file server for Macintosh uses. Performance of the MacFile service increases with an increase in this value. However, the value should not be set lower than 1000 KB. It is especially important that you are well acquainted with memory issues before changing this resource parameter. You cannot change this value from Server Manager.
Default: 0x4e20 (20000 in decimal)
NonPagedMemLimit REG_DWORD 256K to 16000KB
Specifies the maximum amount of RAM that is available to the file server for Macintosh. Increasing this value helps performance of the file server, but decreases performance of other system resources.
Default: 0xfa0 (4000 in decimal)
