Answer 1

As a follow up to my comment, and to show you that my commented commands work exactly as given, (to remove all lines within Scan-FtpOut.txt which contain the exact string /1001214955/ or which contain the exact case sensitive string /WENP/, and output those to Ftp_New.txt).
Here is an example Scan-FtpOut.txt file:
200 PORT command successful.
150 Opening data connection for /WENP/Faketest (467 bytes).
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
200 PORT command successful.
150 Opening data connection for /1001214955/Faketest (467 bytes).
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
Here are the contents of Ftp_New.txt after running #%SystemRoot%\System32\findstr.exe /R /V "\/1001214955\/ \/WENP\/" "Scan-FtpOut.txt" 1>"Ftp_New.txt":
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
Here are the contents of Ftp_New.txt after running #%SystemRoot%\System32\findstr.exe /R /V "[/]1001214955[/] [/]WENP[/]" "Scan-FtpOut.txt" 1>"Ftp_New.txt":
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec
Here are the contents of Ftp_New.txt after running #%SystemRoot%\System32\findstr.exe /L /V /C:"/1001214955/" /C:"/WENP/" "Scan-FtpOut.txt" 1>"Ftp_New.txt":
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec.
200 PORT command successful.
226 Transfer complete.
467 bytes transferred in 2.845 seconds. Transfer rate 0.167KB/sec
As you can see the results of each of my initially offered commands show exactly the intended results!

Answer 2

do it with 2 commands
Find /V "/1001214955/ | /WENP/ " Scan-FtpOut.txt > Ftp_New.txt send {Enter}
Find /V "/1001214955/ -o /WENP/" Scan-FtpOut.txt > Ftp_New.txt send {Enter}

The PowerShell that is available on all supported Windows systems has a much more complete implementation of regex than does findstr.exe. Using a PowerShell regex means you can use the many sources of regex information available on the net.
Based on https://stackoverflow.com/a/7801667/447901, here is how it could be done in a [cmd] script or command.
powershell.exe -NoLogo -NoProfile -Command ^
"(Select-String -Pattern '^(?!.*(/1001214955/|/WENP/)).*$' -Path .\Scan-FtpOut.txt).Line >'.\Scan-FtpOut-New.txt'"
It would be less convoluted and more easily understood if the script is written in [powershell] and not [cmd].
