I have WSUS 3.0 installed on one of the Domain Controllers in our network.

Whenever I want to generate a report in Excel format I receive the following error:

An error occurred during local report processing.
An error occurred during rendering of the report.
An error occurred during rendering of the report.
This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

I passed by a Microsoft KB article: http://support.microsoft.com/kb/935434
I do not know if this applies for me.

Any help will be greatly appreciated.

Regards,

Sounds like your server is set for FIPS security compliance, is this required on your servers?
To turn it off you can change the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\fipsalgorithmpolicy registry subkey from 1 to 0. May require a reboot to work properly.

Hi sweeneya,

After I applied your fix, and worked with WSUS reports.
I found out that the same error popped up today when I tried to generate some excel report.
I went to the registry key, I found out that it was reverted back to its old value although I did not touch it.
Have an idea why might this have happened? How can I make the change permanent?
I do not want to restart the server every now and then to produce an Excel report.

Thanks

Check the local security policy, GPO's or domain controller policy for the following setting and see it is enabled there:
Local Policies -> Security Options -> System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing

Yes, I guess that will be the one. It was configure on the Default Domain Controllers GPO.
This does not need a restart actually.

I will try today after working hours and tell you.
Thanks again
