xcopy fails to copy files when batch file is executed as seperate process

Question

Hi,

i have this batch file - myCustom.bat which has following code in it -

  set dest_server=\\myRemoteSrv\Builds

  set dest_build_loc=%dest_server%\%2%\

  echo %dest_build_loc% >> buildLocLog.txt
  echo Copying  %1\myTest.zip %dest_build_loc% >> buildLocLog.txt

  xcopy  %1\myTest.zip %dest_build_loc%  /D /F >> xcopyOutputLog.txt

when i call the above batch file from command line with - c:> myCustom.bat c:\Builds\123 123 then everything works fine - c:\Builds\123\myTest.zip is copied successfully to \myRemoteSrv\Builds\123\myTest.zip (the dest folder gets created if it is not there)

But the same batch file fails to copy the file when i am executing it as a separate process - when i do this spawn a new "cmd.exe" process by passing "/c myCustom.bat c:\Builds\123 123" as arguments to it -

note that - the batch file is receiving the correct inputs - when i check the buildLocLog.txt i see the following text in it -

\\myRemoteSrv\Builds\123
 Copying c:\Builds\123\myTest.zip  \\myRemoteSrv\Builds\123\ 

but the xcopy command fails- the xcopyOutputLog.txt contains following lines in it "0 File(s) copied"

could someone please let me know where i am going wrong ?

thanks,
