Here is an example of a VB script I used to set the domain suffix search list on a Windows machine. I just saved the following in a file with a vbs extension and executed the script.
SET WSHShell = CreateObject(“WScript.Shell”)
WSHShell.RegWrite “HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\SearchList”, “mydomain1.com,mydomain2.com”, “REG_SZ”
I made this modification on an HP DL-360 with dual 1.3 GHz processors, 2GB of memory, and RAID 1 drive (two drives mirrored). It made a huge improvement accessing a directory with a lot of files. According to Microsoft (, ), the setting is increased in Windows 2003. I set in my NT 4.0 server to 16,644.
The SizReqBuf value is stored in the registry under the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Value Name: SizReqBuf
Data Type : REG_DWORD
Data : 512 – 65535 (bytes in decimal, or 200 – FFFF hexadecimal)
Default : 4356 Specifies the size of request buffers that the server uses.
