Drive Mapping,Logon Script | Problem and Solution


This one comes after a real long time, I was busy shifting my residence & getting familiar with the new place where I stay. things have settled down now & time to be back with thing that I enjoy, writing about my latest experience dealing with issues related to Exchange & Active Directory.


I was asked to work on a logon script that enables the user to automatically map some network drives when they login to the domain. Being a core Messaging person I wasn't too familiar with the requirement, but like all other days I figured it out quickly.





First of all I need to know which drives needs to be mapped & to which drive letters, so for example say that i have two drives that i need to map to Drive Letters V & W








1. So i need to ensure there are no drive mappings with these dive letters that user has done manually, for this I use following command which remove any drive mappings with the letters V & W

NET USE V :/Delete
NET USE W:/Delete

2. Then I need to add my Drive Mapping to these drive letters, say that the drives that i need to map are

ECHO OFF

IF NOT %errorlevel% EQU 1 GOTO NORMAL_USERS

NET USE J :/Delete
NET USE K:/Delete
NET USE J:\\192.168.1.1\Sales1
NET USE K:\\192.168.1.1\Sales2

:NORMAL USERS

IFMEMBER NORMAL_USERS

IF NOT %errorlevel% EQU 1 GOTO QUIT
NET USE V :/Delete
NET USE W:/Delete
NET USE V:\\192.168.1.1\Share1
NET USE W:\\192.168.1.1\Share2

:QUIT

exit

This worked like a charm, only problem was when the users login to their laptops with the cached credentials, ( outside the corporate network) these drive mappings caused timeouts to these drives causing extreme slow performance logging in ...causing lot of frustration.....




.......So we modified the script to use non persistent mapping ( equivalent to uncheck the box "Automatically connect at the next logon)

For this we need to post fix every Net Use command that maps a drive with /Persistent:No , this resolved my final issue with this small but interesting task....
