Unable to log into Windows Server using ID and PW

I am running 3 private servers, all are Windows Servers, (All 2008 R2). A couple of days ago I went to connect to one of them and when I try to 'Go, connect to server' choose the relevant server, it asks me for my user ID and PW. As I am the only one who uses these servers I always use the servers Admin ID and PW.

2 Days ago, the login window started shaking and asking me to type the name and PW despite trying numerous times it will not let me access the drives.

A couple of things to keep in mind:

The other 2 Windows Servers I am having no problems with. (They are all running the same Windows 2008 R2.)

I have 3 Macbook Air's and one Mac Mini and none of them can connect to this one server, whilst they can all connect to the other 2.

I can also connect to this server using Microsoft Remote Desktop for Mac. (But I cannot access the drives using network.

I also have 2 laptops in the house running a Windows OS that can access all 3 servers without issues. I also have 3 Apple TV's that can access these servers with out issues.

It is only the 3 Macbook airs and Mac Mini that cannot.

All 4 mac Devices are running Sonoma 14.2.1

Any help would be awesome..
