I have a server computer with windows 11 that shared some folders. This folder has security and network permissions to access.
From one computer, with windows 11 too, I give the credentials when I am prompt for it, but I get and error network that I don't have permissions for this user.
I try with another computer, with windows 11 too, I use the same credentials and I can access in this case.
If in this second computer I shared a folder, from my first computer I can access too, so it seems it is a problem only with the server computer.
I have never check to remember credentials, I prefer to write each time I want to access, but anyway I tried to delete all the credentials of the user, but the problem still persists.
I have try to access from another user account from the computer that has the problem, and I have the same problem, so it seems the problem is general problem, not a problem of a user account.
I don't know what else I could try, but I would like to know how to solve the problem or I will have to reinstall the system but I would like to avoid this solution.
Thanks.
Have you granted access to the user account on both the share permissions and the folder permissions? Or are you using "Everyone" to grant access?
Check the Security eventlog on the "server" computer. Do you see any errors when the other computer tries to connect?
Run the troubleshooters and see if they detect any problems.
Yes, the user has permissions in both, in security and in sharing options.
I am not allowing to everyone user, just a particular user, which credentials I use when I am prompted when I try to access to the shared folder.
If I use the credentials of this user in the first computer I get the error, but if I use this credentials from another computer I can access to the computer.
I have tried with another computer with windows 11 and another with windows 10, in both cases I can access with the credentials of the user that is allowed in the server.
From the first computer that has the problem, I have tried to access from another user account, a admin account, and the problem is the same, so the problem is not with a user account, it seems it is a general problem with the computer. So the problem wouldn't be solve if I create a new user account.
Did you check the security eventlog?
Did you run the troubleshooters?
Also in event viewer, under Applications and Services Logs, navigate to Microsoft\Windows\SMBClient and \SMBServer, check the various logs there for errors.
IIn the SMB Client I don't have errors, bu I have a warning which ID is 31018. It is related with AllowInsecureGuestAuth, that it says it is not configurated with the default value in the register.
In the SMB Server I have an error, with ID 1006. It says that they denied permission to computer with IP x.x.x.x. This has sense, because it is the IP with the computer with the problem, and how the IP is the same no matter which user account I use, it has sense.
It says that the shared resource denied the acess to the client.
I cannot find an SMB event id 1006 documented anywhere on the internet. Is there any other text included in that event that might explain the reason that it blocked the IP?
I reread your replies and you mention "server computer", "one computer", "another computer", and "second computer". Beyond "server computer", it is not clear which machine you are referring to.
PC1 is Win11 and has shares. This is your "server".
PC2 is Win11. This is the machine that has the main problem.
PC3 is Win11 and has a share.
PC4 is Win11.
PC5 is Win10.
PC2 is not able to access shares on PC1. This is the main problem that you need to solve.
PC3, PC4, PC5 are all able to access shares on PC1.
PC2, PC4, PC5 are all able to access shares on PC3. (Note PC2 listed here.)
Is that correct?
On PC1 did you run the "Incoming Connections" troubleshooter?
On PC2 did you run the "Shared Folders" troubleshooter?
Is the network connection on all machines configured as "Private"? Open a Powershell prompt and run this command.
(Get-NetConnectionProfile).NetworkCategory
Temporarily disable the Windows Firewall on PC1. Does that solve the problem?
Hello Dave,
I think that an example of this 1006 event is shown in full here: https://social.technet.microsoft.com/Forums/ie/en-US/399b3909-66a4-4593-8a25-7d8be79821e0/smb-server-security-error?forum=winserverfiles

Thanks Gary.
Got any ideas on this one? If I'm reading his replies correctly, he can access the share from another Win11 machine using the same account. So, I wouldn't think it was the permissions, but sadly, we can't see what he's doing. I was thinking an SMB1 related problem or one of the network access settings in group policy. (Local computer policy since he's probably not in a domain.)
Dave
Hello Dave,
Sorry for that terse reply - it was almost midnight here (in Switzerland) when I sent it.
The approach that I try to take with problems like this is to request "trace" data - that can sometimes be a simple network trace and sometimes a trace of ETW providers (Event Tracing for Windows).
Either type of trace would be a big help here.
The main problem with trace data approach is guiding someone through the trace data collection process and informing them about the risks, benefits and methods of sharing the data.
I don't think that this will turn out to be an SMB1 problem since the problem occurs between two Windows 11 systems.
Gary
I have this system:
Server, with windows 11.
Computer one, this has the problem. Windows 11
Computer 2: no problems, with windows 11 (fresh installation)
Computer 3: no problems with windows 10.
I have tried to set the ethernet connection as private and the problem persists. Anyway, the other computers with no problems has the network setting as public.
The problem it seems in the server, that for some reason it denies connection from the computer.
I have tried to change the IP of the computer, because in the description of the error in the event viewer it indicates the IP of the computer, but the problem persists. So it seems that the server don't accept connections from this computer for some configuration.
I have realize that I am not prompted for credentals when I try access to the shared folder, when I have never check the option to save credentials.
Also, in the event viwer of the server, I can see that the user that tries to connect is [NameServer]\UsuerComputer1. It is odd, the computer name is the server but the user is the user of the computer that has problems. This user doesn't exists in the server, it is what I want, I want t o be prompted for credentials when I try to access.
However, control panel, in users accounts, in credentials manager, I don't see any credentials related with the shared folder. So I don't know how I could delete the shared folder credentials.
If all of these machines are on your own private network, then their network should be set to private.
Did you run the troubleshooters?
Did you temporarily turn the firewall off?
yes, I have tried as private and I have disabled the firewall, it doesn't solve the problem.
For the last time.... Did you run the troubleshooters?
Yes, and it doesn't detect any problem.
So I don't know how I could delete the shared folder credentials.
Open one command prompt with "run as administrator" and another without "run as'. In both run the "net use" command. If you see any entries run a "net use /delete".
Thanks for your help.
Sorry, the syntax of "net use /delete" is incorrect and the help of the command is shown.
You have to add in whatever drive letter that you have mapped.
net use x: /delete
OK.
I don't have any drive mapped now, just put in the file explorer \x.x.x.x\MySharedFolder.
Do you get prompted for user/pswd?
If not, in the non-admin command prompt use the net command to map the drive.
net use x: \\server\share password /user:yourusername
don't have any drive mapped now
Does that mean that you had a drive mapped and you successfully deleted it?
Are now able to map a new drive and access the "server"?
In the past, when I could connect to the server, I had a mapped network.
But know I can't connect neither mapped network nor shared network folder. The problem is related with the permissions, no matter how I try to connect to the shared folder.
So grant the account access to both the share and the folder permissions. Verify the access with the Effective Access tab.
The user has permissions for read and write.
In fact, I use the same user to access when I try from the different computers, and I only have problems with the first computer. So it seems the problems is not about permissions of the user of the server.
Also I have notice that the problem is in the server, that it receives a user like \[ServerName]\UserNameInComputer1 instead of \[ServerName]\UserInServer. This I can see in the event viewer in the server.
Sorry, you must have done something in the past to cause this problem.
On computer1, define a UserInServer account with the same password as the account on the server. Log on to computer1 with that account and try to access the \server\share. You should not be prompted for a password.
Or, on computer1, define a new someOtherUser account. Log on to computer1 with that account and try to access the \server\share. You should get an access denied. Then try to map a drive with the UserInServer account. That will at least tell you if the problem is with computer1 itself or with the UserNameInComputer1 account.
yes, if create a user with the same name and password than the server, it works, but then I can't use my normal user.
And if I create a user in the server with the same name and password that I use in the computer, then it works too, but I don't want to avoid to have to create this user in the server, because it is not the behavior that I want.
I am starting to guess that the best solution it is to reinstall windows, but really I would like to know how to solve this problem, that it is true is the first time that I get it, but I wouldn't like to have to reinstall windows if it happens more times.
Create a SomeOtherUserAccount and log on with it. Then map the drive with the UserInServer ID. If that works then you know that the problem is centered around the UserOnComputer1 account. Copy it's Desktop and Documents folders to C:\Temp and then delete that account. Verify that it's profile (C:\Users\UserOnComputer1) got deleted. Then recreate that account. Deleting a user should be much easier than reinstalling the OS.
Are you sure that you checked the saved credentials?
In the computer with the problem, I tried with another user account, an administrator account, and the problem is the same.
Also I have delete all the credentials in the user that has problems, but how the problem happens no matter which user I use, I knew this is not the solution, but I deleted them anyway.
Sorry, I have no idea what you did to cause this problem or how to fix it.
Really it is an odd problem, so don't worry, I know you try your best and I really appreciate it.
Thank you so much.
