System error 85 has occured in SQL Server 2005

Question

I'm executing a batch file from SQL Server using this code:

exec sp_configure 'show advanced options', '1'
reconfigure
exec sp_configure 'xp_cmdshell','1'
reconfigure

exec xp_cmdshell '" D:\network.bat"'

and the neywork.bat contains the below commands

rem disconnect and re-set upn network drive connection
net use z: /d /yes
net use z:\\mlisfile07

Here the z: is mapped to some other path, but in the output it is showing as

network connection could not be found
system error 85 has occured

Answer 1

You are missing a space between the drive letter and the network path:

net use z: \\mlisfile07
         ~~~

Answer 2

The possible reason is that your logged in SQL-SERVER user doesn't have administrative permissions.
