Check remote file existence on multiple Windows servers - batch-file

Question

I need to check a file status (existing? or last modified date) on multiple remote Windows servers (in LAN). The files are accessible via UNC path. The remote PCs need a user name and password. It's best to be some sort of script.
I am not system admin, but asked to do this by my boss because each of these PCs are host of SQL Server and the file is a backup of database. I am a SQL Server database developer. I was trying to do it using T-SQL, but just found it not geared to do this (although maybe doable).

Answer 1

Create a batch file like (say check.bat):
#echo off
set list=server1 server2 server3 server4 serverN
for %%s in (%list%) do (
echo Logging in to %%s
net use \\%%s\shared /user:mydomain\myuser password
echo Checking file existence on %%s
if exist \\%%s\shared\file.txt (
echo File exist on %%s
) else (
echo File does NOT exist on %%s
)
echo Logging out
net use \\%%s\shared /delete
)
