WMI Windows Updates Status Error after Server Update

Hello, we've got an error on some our servers after the last comulative Windows Updates.

The Error message:

"Der WinRM-Client hat einen Status in Bezug auf eine ungültige HTTP-Anforderung (400) empfangen, aber der Remotedienst hat keine anderen Informationen zur Fehlerursache bereitgestellt."

It's a little confusing for me since on Servers the WMI service works fine and on some we got this error message and we didn't change anything.

Thanks in advance.

Hello,

Is the probe running the sensor and the target device in the same domain? What permissions does the user has that is entered in the "Credentials for Windows" in the device setting? What do you use as the address of the device (IP, DNS, or FQDN)?

No, the're not in the same Domain, but it doesn't matter, since some of the other server w/o that error message are in the same domain like the server who got that error. The User has the full permissions. Mostly IP but some w/ DNS or FQDN.

However we solved this error by our self: go to regedit on the server(-s) and add those 2 lines in the following path:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters] "MaxFieldLength"=dword:0000ffff "MaxRequestBytes"=dword:0000ffff
