Unable to login to windows 2008 server locally or Remotely

All of a sudden, our Windows Server 2008 will not allow me to log in using the admin account (it is the only account on the server). We also have a server 2016 operating system that was working fine yesterday and now it does not allow me to log in this morning. I am not able to use a remote desktop to connect either. Some of the users in the building can connect to some of the shared drives between the two servers and others can not. Also, When I use Repadmin /replsummary in the CMD or Powershell the result shows the "Not enough server storage to process this command" error is displayed and when I restart, the problem is solved and I can log in to the server again. this problem occurred every 2 days.

Any help would be greatly appreciated.

    Please run;

    Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log
    repadmin /showrepl >C:\repl.txt
    ipconfig /all > C:\dc1.txt
    ipconfig /all > C:\dc2.txt

    then put unzipped text files up on OneDrive and share a link.

    Hello @Moiano

    As unpleasant it might sound you might be affected with some virus. My recommendation is to first bring the server down and scan it with an offline antivirus disc. If you're not infected with anything, then check your event logs for password change events and failed logins. You will be most interested in seeking the origins of those changes. However, in order to see the Event Logs, you still need to be able to log in.

    This issue may occur if the IRPStackSize registry entry on the server is set too low.

    To resolve this behavior, increase the IRPStackSize value in the registry:
    Click Start, and then click Run.
    Type regedit, and then click OK.
    Navigate to the following key:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
    In the right pane, double-click the IRPStackSize value.

    NOTE: If the IRPStackSize value does not already exist, use the following procedure to create it:
    In the Parameters folder of the registry, right-click the right pane.
    Point to New, and then click DWord Value.
    Type IRPStackSize.

    IMPORTANT: Type "IRPStackSize" exactly as it is displayed because the value name is case-sensitive.
    Change the Base to decimal.
    In the Value Data box, type a value that is larger than the value that is listed.

    If the IRPStackSize value was increased using the procedure described in step 4, the default value is 15. It is recommended that you increase the value by 3. Therefore, if the previous value was 15, type 18, and then click OK.
    Close the Registry Editor.
    Restart the computer.
    If the problem persists after completing the preceding procedure, try to increase the value of IRPStackSize even more to a maximum of 50.

    Hope this helps with your query!
