To use a mapped drive in SQL server make sure that the mapping is done using the xp_cmdshell procedure.
Before the extended procedure can be used it has to b enabled as shown below
EXEC sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
EXEC sp_configure 'xp_cmdshell',1
GO
RECONFIGURE
GO
thereafter map the drive so that SQL understands it
EXEC XP_CMDSHELL 'net use Z: \\192.168.100.36\nansql'
