Using the Registry
To manually configure the DNS suffix search order, configure the following Registry value. Add
the DNS domain names in the order that they should appear in the search list:

[HKey_Local_Machine\System\CurrentControlSet\Services\Tcpip\Parameters\]
"SearchList" = REG_SZ:"< DomainName> ","< DomainName> ","< DomainName> "

■ Note In this case, multiple entries are separated by commas instead of spaces.

To configure the DNS suffix search order to use the Windows default, set the previous
Registry entry to a blank value.
To configure the connection-specific DNS suffix, configure the following Registry value:

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
Tcpip\Parameters\Interfaces\ {<Interface GUID>} \]
"Domain" = REG_SZ: " <DNS suffix> "

To prevent the computer from performing primary DNS suffix devolution in a name
resolution process, configure the following Registry value:

HKEY_LOCAL_MACHINE\System\CurentControlSet\Services\Tcpip\Parameters\
"UseDomainNameDevolution" = REG_DWORD: 0

Using VBScript
This code will change the DNS suffix search order to mycompany.com followed by east.
mycompany.com . Simply modify the arrNewDNSSuffixOrder array with the appropriate DNS
domain name values for your environment.
