Copying executable files from a network drive?

garlin · Jul 23, 2025

That doesn't mean it's not happening, you haven't tried temporarily disabling ESET and re-testing a file copy?

That was the first thing I tried.

The only fix is to give full access rights to the account you want to share the files with. If you are the only one using your network computers, you could even grant full access to Everyone (including Guest and anonymous logins) to the shared folder. Also exclude the shared folder in ESET in both the host and the other computer, so it doesn't scan while copying and doesn't block the transfer.

You've lost me there, I'm afraid.

I have an external drive plugged into the modem/wifi-router. There are several computers that can also access that drive, but they're all mine, so granting full access is not an issue. None of the computers are set up to have shared folders on the computers, just common access to the network drive.

Where do I "give full access rights"? ESET or windows and if the later, where and how? :)

See the settings in the Router. Who has access to the files? Create an exclusion in ESET so as not to scan the network drive and blocking the transfer.

I'd already tried excluding the network drive in ESET, that made no difference. Disabling ESET made no difference. Settings on the router are that all users have read/write access.

Looks like the router is blocking automatically any executable file for security reasons and of course there is no setting to disable it. You have to forget the router and just connect the drive on any computer and share it.

Except the router allows copying of the afflicted files on the drive to and from a WIn10 machine and I have tested it with another Win11 machine that was upgraded from Win10 and the files in question can be copied onto that pc without issue. That pc had the drive mapped in Win10 and was later upgraded to WIn11, with the drive continuing to work as expected.

What fails is copying most (but not all!) exe files from the networked drive into an new WIn11 pc, ie one that has not had a previous version of windows installed and then upgraded to Win11. All the pcs have the same ESET anitivirus installed.

Then it has to be some Windows security setting. See at Device Security or anywhere it might make sense. Also see Advanced Sharing Settings. Compare Windows 10 and 11. The culprit must be disabled in Windows 10 and enabled in Windows 11.

Ps: Just a thought! As far as I know SMB version 1.0 is disabled in Windows 11 by default. Try enabling it. Open Control Panel, switch from category to large icons, open Programs and Features and then Windows Features. Check the box to enable SMB 1.0

Sometimes just disabling your security program isn't enough if there's any corruption within it. You might need to uninstall it with the proper uninstaller then reboot. Windows defender then kicks in. Check if now working or not. Re-install ESET and re-register.

SMB1 is enabled. No obvious settings in Device Security, nor in Adv Sharing Settings. I agree it looks to be a win11 security setting and one that is not enabled if you upgrade but only on a fresh install. I'd come to that as the likely conclusion before I asked for help.

It's a brand new laptop. I'd completed the Win11 install (using a local account, not a MS one), then connected to the internet, ran win update, downloaded ESET & installed and then tried to copy over software from my desktop to install via the network drive. Ran into the exe problem, so posted here whilst continuing to install software using a plug in drive and renaming the 'exe' file type for transfers via the network drive.

I'll give that a try, but I'm not going to have the chance to spend the time needed for that for a few days .. but it's worth a try. ESET does an ongoing self-integrity check, so if there was any corruption it should pick it up and squeal for attention.

I have seen this weird issue before. Disabling a third-party antivirus (I had Norton Antivirus back then) is not enough and you have to uninstall it and reinstall it. Since it was long ago at Windows XP, I hadn't thought if that. Give it a try, you never know.

I'll give it a try, but I wont have a chance to do it for a few days.

Thanks for the suggestions!
