[Samba] Share mappings with error 85

[Ricardo Campos]

Hi, all.

I have just installed a Samba AD-DC, with a file server. I know that this
is not ideal, but this is what I could do now.

I have many shares and now, with windows 10 clients I face a problem: the
first time the user logs in, all maps work. From this point ahea, no more
mappings and the error 85, which informs that the drive letter  has already
been used.

The mappings are in a logon.bat script, executed in login time, through a
GPO.

My first question is if someone has faced this error and what solution was
applied.

The second is what information I need to send in order to inform the
context.

Samba AD-DC version  4.15.13-Ubuntu is installed in a Ubuntu 22.04 LTS.

The windows client used is windows 10 (it works well in windows 7)

I cut a bunch of shares that seem to be unnecessary for the moment.

I'm not sure how I can send information on GPO.

I thaks for any help.
