unmounting a network drive

A batch job does the following:

net use x: \\<servername>\e$
copy file.txt \\<servername>\e$\<directory>\
sleep 20
net use x: /delete


We find residual cmd and net processes left running after the "net use x:
/delete" however there is no sign of the drive. It's like it unmounted the
drive but for some reason did not close out the "net use" command. The drive
cannot be found mounted no matter how you look, and yet the same drive letter
can be re-used without reboot.
Not all our servers do it and and the ones that do it, don't necessarily do
it every time, but I have to clean out bunches of these since the bat file
runs every hour of every day.
What can be the cause of this and how do I fix it?
Thanks in advance

Perhaps you'll find out what's going on by replacing the line
net use x: /delete
with these lines:
echo %date% %time% %UserName% >> c:\test.txt
net use >> c:\test.txt
net use x: /delete 1>> c:\test.txt 2>>&1

Note also that if you run your batch file as a scheduled task then drive X:
is probably neither visible nor accessible. You must use UNC coding for your
scheduled tasks.

I would insert "net use X: /del" as line 1 in case the X: drive is already in
use.
Also use "net use x: \\<servername>\e$ /persistsent:No"

But if your need is a simple as you say just use
copy file.txt \\<servername>\e$\<directory>\
and get rid of the drive mapping.
