XADM: Explanation of Exchange PCMTA's /Z Parameter

MORE INFORMATION

This parameter is stored in the Registry under the PCMTA instance created by the administrator:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
                            \<PCMTAinstance>\Parameters
				

The values DrivesUNC and DrivesWAN hold the connection information for the MSMail postoffices. The format is as follows:

   DrivesUNC:REG_MULTI_SZ:\\serverA\share1 /Z \\serverB\share2 /Z ...
   DrivesWAN:REG_MULTI_SZ:\\serverC\share3 /Z \\serverD\share4 /Z ...
				

Note: DrivesWAN connections are set by either disabling dispatch on the instance of PCMTA or selecting not to pick up mail for a particular postoffice.

When connection information is required, the /Z parameter will be followed by the encrypted Connect As information. For example:

   DrivesUNC:REG_MULTI_SZ:\\serverA\share1 /Z DOMAIN\user 742SF32JA234
   234J53AA001
				

Because all these parameters are automatically entered by the Microsoft Exchange Administrator program, there is no need to manually edit the Registry with this information.
