I have just updated to Windows 11 and the WHS Connector has disappeared. Windows does not allow me to reinstall it. Does this mean the end of the road for this fantastic backup system or can anything be done?

I have not tried win11 yet but I would bet SMB1 is not installed.
GOTO Turn on windows programs and features if that still exists.
And see if SMB 1 is available to install.

Just found this after posting.

If it were me I would uncheck the automatic removal option.

For me I am going to wait till I get a nag to upgrade to win 11

I just added a Windows 11 laptop to my home mix. I am successfully using whs v1with W7, W8.1 and W10 clients. When I tried to install the connector on the 11 machine, I get past the MediaSmart app installation app and all the way through the connector software install until where you enter your password for the home server. This results in an error - "this operation cannot be completed at this time". From there, connector uninstalls. I am setup as Private network, file sharing turned on, smb1 is all turned on, and I can rdp into my home server. I also tried creating a simple password with no special characters. On one reinstall attempt, somehow (not sure the sequence), the connector actually got installed (greyed out icon in taskbar) -- however, when I tried to login by adding password, I got the same operation cannot be completed error. Also, sometimes, after the connector install unwinds, I get a "Wake on Lan configuration failed" error message. Must be something fairly simple - hoping W11 is not the end of the road ...

Adding some additional information about this issue. When the password is rejected per above, the event viewer has this error message: "Windows Home Server protocol mismatch. This computer uses protocol version 6.0.3436.0, but partner computer ServerXYZ uses protocol version 6.0.2423.0. A connection cannot be established."

This error has a history with the Connector install and backup issues going back to the early days of WHS. But I could not find a definitive explanation or resolution to this error. Some in fact noted that sometimes the connector installs even when this error occurs. So, doesn't really help. And the versions referenced are both valid software versions I believe for the latest updates. On my server 6.0.3436.0 is the version of the Remote Access program, and 6.0.2423.0 is the version for the Server Console, Backup & Restore and Drive Extender programs.

I also looked on the Server side and found this application error: An SSL connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed. I believe this is a SSL/TLS issue. Over my head here but I think Windows 11 drops TLS 1.0 support completely. I'm not clear why the client app can't use the protocol it needs but maybe Windows 11 forces a higher level protocol?

I thought I would add some more info to this thread in-case it inspires anyone to continue investigating. I still run WHS v1. It backs up several computers so I was sad when I discovered it would not connect with my new Windows 11 laptop.

Given that my Windows 10 21H1 machines still connect, I looked at https://docs.microsoft.com/en-us/window ... s-10-v20h2 and compared the CipherSuites in Windows 10 with Windows 11. There are two CipherSuites in Windows 10 that are not enabled in Windows 11; TLS_RSA_WITH_3DES_EDE_CBC_SHA and TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA.

You can use Windows Powershell to enable these. On my Windows 11 machine I used the Get-TlsCipherSuite -Name "<insert one of the above>" to confirm it was not enabled and then used the command Enable-TlsCipherSuite -Name "<insert one of the above>".

Full details of these commands are at https://docs.microsoft.com/en-us/powers ... ver2019-ps.

Regardless, it didn't work and I still have the same problem as the OP.

Maybe I missed something, or maybe WHS v1 with Windows 11 flat-out isn't possible??

Kind Regards

I just had to get a couple new laptops and I went with Win11. I have the same issue.

You can still access the folders on the server--but the connector software doesn't work. So unless a fix is made by the smart guys I'll have to upgrade one of my other servers. I'll see if any of the WHS boxes running other software are able to work. I'll post what I find out here.
