Clients not receiving updates

Hi,

I have some issues with some clients here who are not receiving any updates.

When checking the ScanAgent.log and WUAHandler, i receive an 0x80024407 error which means according to the error lookup of CCMTrace " Same as SOAPCLIENT_SOAPFAULT - SOAP client failed because there was a SOAP fault for reasons of WU_E_PT_SOAP_* error codes.”

I have looked for this error on Google and i have tried the things they mentioned (changing a parameter in the web.config, check if SSL is disabled in IIS Server, doing a IIS Server reset afterwards), but to no avail.

I'm not sure if it's a network issue, as this happens with clients from different locations. Not all devices have this issues, but the list comes bigger with each day.

SSL is disabled on the SUP, management server as the IIS WSUS pool.

I have also done the following things on the clients with issues:

- Reinstall SCCM client

- Reset the WSUS client (by stopping the server and removing the content of SoftwareDistribution)

- Recreated the Registry.pol file

There is also no other errors found the IIS logs and SCCM logs.

I have already spended the whole week (combining with other urgent issues) looking at this, but i can't simply find an solution to this.

Last resort is redeploying those devices, but as those clients are spread across the globe this will take some times and management here starts to be annoyed because the numbers are incorrect.

Any idea what can cause this issue and how to solve it?
