I am trying how to allow Windows 10 smb client (pc1) login to Windows 7 smb server (pc2). It says “Password Invalid” even its valid, same issue on new account.
If i try to access Windows 10 smb server(pc1) from Windows 7 smb client (pc2), the issue doesnt happen. Which parameters on Windows 10/11 i must check to solve this problems? (both machines are configured as client/server).
I dont know if this issue happens with Windows Server 2012R2 smb servers login from Windows 10/11 smb clients.
pc1 to pc2 login = Password Invalid even its valid pc2 to pc1 login = Login Sucessfull
I recommend testing this out using lower limits and smaller file sizes. I also recommend testing by sending to a non-Outlook domain.
I went through this today, and partly used this site as a resource. I also realized through testing (by sending to a Gmail account, with a receiving limit of 25MB) that the response was being generated by Outlook.
I recommend lower limits because OWA has limitations on sizes documented by Microsoft and referenced in another comment.
As an example, if you’re sending a ~42 MB file, and using OWA Outlook, then the limit needs to be more like 60MB (not that it’s the correct percentage, only that I know making a similar change resulted in success).
My testing recommendation would be to send a file to a Gmail account that you know is less than the Outlook limitation but greater than the Gmail limitation. If you still get the 35MB response, then you know it’s Outlook and not Gmail.
“OWA, however, restricts the size of the message you can send to 25 percent less than the configured allowed maximum send size.”
I don’t know if the above is relevant (especially considering that 110 MB is right at the edge of 25% of 150 MB), but I tested this out myself and had to increase my limit because the file I was testing with was within that margin.
The “remote server” part of the response if probably throwing you off, but the important part to focus on is that it’s indicating that the message is too large for the sender and not the recipient. Typically, if the recipient rejects the message, you’ll get: “Your message wasn’t delivered because the recipient’s email provider rejected it.”
I need your help regarding the code with TFTP as you were added TFTP commands in last . Can you share the code with TFTP after editing i want to take configuration backup in config file format like TFTP take configuration backup and put this backup on TFTP directory. Appreciate if you can help me.
Kudos for publishing this method in Powershell. Years ago, I wrote the same app in Delphi, but use CRC32 as the hashing tool.
Part of that app is a non-recursive file search that starts at the specified parent directory, then searches all child leafs below. Each filespec is recorded in a TOPAZ (DB4) flat file database which is a source-code level toolbox for Delphi.
On the first pass, I keep track of all three file create/modified/accessed time stamps, the fully qualified file name, and the file size in the database.
The DB is indexed on file size and all identical-sized files are further examined. Those with different file extensions are skipped.
Those with identical extensions are then each calculated for CRC32 and stored in the database. This is a slow process when examining 30,000 to 50,000 files. I rewrote CRC32 into Assembler but got no appreciable boost in performance, as the Delphi compiler is very good at optimizing code performance. Profiling the code, the CRC32 is indeed the slow point.
Last, I don’t delete duplicate files, but rename them with a representation of their fully qualified file name, i.e “root-mydocuments-pictures-vacation.img1234.jpg”, then move them all as unique file names to a common directory called !Duplicate Files for safe keeping until certain to delete them.
Thank you so much for this. I was about to rebuild my WSUS servers because I could not get the “Basket” add-in to appear. It is a pain to add each one manually, but at least I have been able to add the patches I need to add the out-of-band patches I need for this month.
The are multiple techniques to find duplicates, but the most challenging part is scanning directories efficiently. Get-ChildItem is sequential and limited to 260-character path length (solved in PS7). In order to scan a disk with millions of files, I created a C# app, using p/invoke FindFirstFile thus solving the path length issue and using async functions and a channel. Scanning a 12TB disk for files over 1MB is less than three minutes (including the file system owner!). Most of the time, file name, date and size returns 90%+ of the duplicates. Hashing is an expensive operation on millions of files. Putting a threshold on the size helps with performance too.
De-duplication can also be used so you don’t need to care about duplicates. It has a ‘cost’ of course.
Thank you for this. Excellent. i checked your blog, too. Enough there to keep me busy for the rest of my life. I won’t need any other sources for what I want to know, looks like. I’ve got big problems with duplicate files, I know. But i also know from experience it is not a simple job fixing it. You have to be very careful, right? Blindly eliminating duplicates can wreck everything I think I have found in the past. But that may have been because my duplicate elimination software was too simplistic – perhaps not checking file length, calling files ‘duplicates’ merely because they had the same name. Which can destroy all your config.txt or similar in a flash. Whatever it was I know I created a real hell for myself in the past by trying to organise files and eliminate duplicates. ‘Organising’ meant collecting like files together in one place. That didn’t work. Moving them is the same as deleting them to software that expects to find them there. Part of the problem is hinted at here where you caution to make backups before doing anything. Well that’s just it. We make backups and then get interrupted before the whole task is complete – which can take a long time when using only ‘spare’ time – and with maybe as many as eight disks to work on, something greater than 10 Terabytes – and there we are during the process with now ‘extra’ duplicates created just for the sake of the exercise! I very much would like a workable technique for this. Currently I have lapsed into the ‘redundancy’ mode: i.e. I never delete anything and just keep buying hard drives. There’s gotta be a better way but it’s not simply running some duplicate finder/eliminator software is it? There has to be some kind of rigorous and careful and fool proof procedure. And I can’t devise it. But this stuff is good. I like it very much. I thank you for it. I
I had LAPS working on all our devices. However, recently I have swapped all devices for new Surface laptop 4 with Windows11 and now LAPS doesn’t work at all. Any ideas? DC is still Server2019, no changes in policies or whatsoever.
