Login Script - System error 85

I am running a basic Login script in Sysvol to map a few mapped drives thru
the Net use: \\server\folder /persistent:yes command.

After the first logon, the next consecutive logons give me System error 85
has occurred. The local device is already in use. The mapped drive is
there, but there is an error in the script.

Is there a better way to re-map drives on each Logon?

What I did in situations with such a script, and is good practice, is to
delete all drives before mapping them to eliminate this error. This also
deletes mappings the users may have deleted the necessary share and mapped
anothe ron the same letter. This ensures all users get the proper mappings
whenever they logon.

net use d: /delete
net use e: /delete
etc.
net use d: \\server\share1
net use e: \\server\share2

I don't use the persistent option when I map drives in a logon script. That
may be causing the error.

Good point, Richard. I don't either. No need especially if deleting them
anyway before re-mapping them

So, is it good practice to use both suggestions:
1. First delete the "specific mapped drives first"
net use e: /delete

2. Can you use the Persistent command "without" adding Yes or NO.
Net use: \\server\folder /persistent
OR
Just don't even include the Persistent command
Net use: \\server\folder

The default is for the mapping to not be persistent, so don't include it in
the command. I would suggest either first remove all drive mappings, or (in
VBScript) trap the possible error when you map drives. If the mapping fails,
remove the drive and try again. That cannot be done in a batch file, so to
be save use the /delete.

After some further testing of the Logon Script using deleting mapped drives,
and removing the persistent, I had intermittant issues. The script would
stop and prompt to click Yes to delete one of the mapped drives. Not sure why
this occurred, but I don't want my users to go thru this.

If I don't add the delete mapped drives, and leave the persistant mapped
drives in the Logon Script...then the user gets the Login Script - System
error 85 ONLY when the drives are already mapped.

Is it any harm to just leave that alone? The error doesn't seem to hurt
anything. If the drives get deleted manually, at least the logon script will
re-add them.

If the users are getting prompted with a question, it may mean the drive
still exists and they are being prompted to map it anyway, or there is an
open IPC session with the machine, such as a current open folder. Maybe it
is a drive they have manually mapped.

Are you deleting ALL drives in your script? I had to in one case, set delete
statements for drives from F: to Z: for this one client to make the script
work. They had drives mapped all over the place.

Forget the persisitent switch. That is like checking the box when manually
mapping a drive to map it every time you logon.
